As a beginner skier living just one hour from Mount Hood, I'm trying to decide whether I should buy or just rent skis when I go; if I do buy, what equipment won't zero out my bank account? John Portland, Oregon

I'm looking for a bike to do a bit of everything: commuting year round, several short rides in spring, and some off-road racing in early fall. What's your opinion of the Gary Fisher 29er bicycles, and how exactly do they differ from other high-end hybrids (for exple, the Cannondale Bad Boy HeadShok or the Kona Dr Dew)? I currently own a Trek 1200 road bike for racing and a worn hybrid for commuting and bad-weather training, but would like something fast, comfortable, and durable for all-around use. Can one bike do it all? Jarle Bergen, Norway

Any recommendations for a beginner's telemarking setup (skis, boots, skins, bindings) to use on groomed downhill runs and backcountry trips? I also recently bought a used Mountainsmith sled in the hope of taking my toddler up and down some trails at a local ski resort. Can this sled handle this type of use or I putting my kid's life in danger? Wayne Cleveland, Ohio

Way back in the late '70s, like many of my generation, I put aside my trusty old Kelty pack in favor of one of those newfangled internal-fre packs: first a Lowe, later a Gregory, and currently a Dana ArcLight. But as geezerhood creeps up on me and I spend more time on trails than off, I'd like to return to my roots and enjoy the better weight transfer and coolness of an external-fre again. My choice is between the Kelty 50th Anniversary Pack and the Dana Loadmaster Terrafre, discontinued but still available on closeout on the Web. Price is not an issue. There's no way I can try them side by side—if you've used them both, which did you think was the better pack? David Portland, Oregon

During a recent backpacking trip my friend insisted that we all wear blaze-orange vests to prevent hunters from mistaking us for ge. My faith in a hunter's ability to correctly ID a target is a bit stronger than my friend's and I resisted his suggestion. I have no desire to be mistaken for an elk and shot by a high-powered rifle, but I also did not want to wear that vest. How valid were my friend's concerns and was I putting myself at risk by not wearing blaze orange? Pete Littleton, Colorado

What's the deal with trekking poles? I seem to be the only one hiking without them. Are adjustability and shock absorption really worth the extra money? Or can I get away with using the beat-up downhill ski poles I bought at my neighbor's garage sale for $2? Kristen Seattle, Washington

My friend and I are planning a one-week ice climbing trip north of Lake Superior to an area known as Agawa Canyon, where the mean daytime temperature is less than zero degrees Fahrenheit. I would like to get a pair of mountaineering boots for the trip that will keep my 41E feet warm, so I was considering either the Scarpa Invernos or Alphas (both plastics). Is my foot width too wide for the Alphas? Having the extra feel of the lighter boot would definitely be a plus in my book. Are there any single-boot alternatives that might suffice, or are doubles my best bet? John Toronto, Ontario

I a strong trail/road runner and interested in doing some snowshoe racing this winter. I would like to buy something that I can use for training as well as racing. Could you give me a few options? Robert Grandville, Michigan

I'm planning on climbing Mount Rainier, so I'm trying to find the best clothing setup. I'm interested in combining a soft shell with a lightweight hard shell, but having a hard time sorting through all of the options. I'm partial to gear from Patagonia and Marmot, so is there anything I should consider between these two companies? Is Marmot's PreCip enough for this type of climb if I use it in combo with a soft shell, or do I need to go with a more substantial waterproof-breathable jacket? Bob Sterling, Colorado

Last year I separated my left shoulder while taking a test run on my son's mountain bike (after "fixing" his front brakes). The physical therapist said I could only use an external-fre backpack in the future. Other friends, and some outfitters, disagree. What's your opinion on the external- versus internal-fre issue? Any specific packs of either ilk that will help keep the weight off my injured shoulder? Michael Front Royal, Virginia

I'm trying to find a pair of cross-country skis that I can use on and off groomed trails. Does such a pair exist? Thanks! Jenni Juneau, Alaska

I've bought the upper-body clothing in preparation for some winter backpacking near the SoCal beaches, followed by Yosemite next summer. But what should I get by way of pants? Would The North Face's Apex's or Arc'Teryx's Gma LTs be too warm? Or should I just pick up some plain or convertible nylon pants? Matthew Claremont, California

Not so much a question, more a comment about ski helmets. I'm a ski instructor and the following is my mantra: If I'm skiing normally, I don't really use a helmet. If I plan on skiing in the park, I wouldn't go without it. However, when it's 20 degrees below and I still have to teach, the helmet keeps me way warmer than any toque, any day. Generally, you know it's cold if I'm teaching in my helmet. Also, helmets for snowboarding are a must. Sometimes, a person just falls way too fast to prevent cracking your head on the hard pack. ber Toronto, Ontario

You recommend the Marmot Equinox as a three-season tent, but will this work for winter camping when temps hit the mid-20s and 30s? I'm looking at some convertible tents (Mountain Hardwear's Skyview 2, Marmot Swallow 2, and The North Face's Nebula), as well as non-convertible options like the Equinox and TNF's Roadrunner 2. Thanks, I just started reading your column and really appreciate the insight. Alexis Syracuse, New York

With all the to-do about soft shells, what's the best way to keep your noggin dry given that most soft shells seem to come sans hood? Eric Fayetteville, Arkansas

I'm an improving intermediate skier who will ski practically everything on the mountain—though not always gracefully! I'm looking for a pair of skis that won't hinder me as I progress, but that won't be too advanced for my current skill level. What do you recommend? Joel Manhasset, New York

Do you have an opinion about panniers versus a B.O.B. Yak for long, self-supported bike touring? I ride a Gold Rush Replica LWB recumbent and planning a solo coast-to-coast ride. David Portland, Oregon

I have very narrow feet and even narrower heels. I have tried just about every boot; my heels slip too much in Lowa's Lady Sports, my feet swim in Vasque Sundowners. I currently trying L.L. Bean's Cresta Hikers, though the first order I made were too small so I'm awaiting larger sizes. But, do you have any other boot suggestions for very low-volume feet? Or are there other ways (other than insoles, thick socks, and lacing techniques) that may help in attaining a proper fit? Debbi New York City

You hear so much about rainjackets, but what about a good pair of rain pants? I'm open to both a lightweight pair like the Marmot PreCip or Sierra Designs Peak Bagger, or an expedition-worthy pant like the Arc'Teryx Beta AR. But what do you think, your gearliness? Jay Northwest Oregon

I having ACL reconstruction surgery next week and thought I'd purchase an indoor bike trainer to supplement my rehabilitation. However, I'm confused by the different resistance mechanisms: magnets, wind, fluid, who knows what else. Are there particular advantages to one over another? Is there a particular make or model you'd recommend? Rob Calgary, Alberta

Four years ago I bought a pair of Limmer Light-Weights, assured by a local in the store that they'd last me 20. I have a habit, though, of wearing them in snow and on glaciers, which has caused the leather at the rand to separate from the midsole, effectively making the boots VERY permeable to water. I'm told that Limmer will fix this problem and resole the boots for $75. Should I fork out the cash or simply buy a new pair of boots? Jacob New York City

Sala, Gear Man! So, you've hooked me up with advice on altimeter watches (I'm very happy with my Suunto, by the way) and Pac NW raingear (which ce in handy when I got reassigned to Ft. Lewis). Now, however, I have a more pedestrian question. Socks, actually. It is rather warm here in the scenic Middle East and my feet are sweating like crazy. I started out with the basic, military-issue black wool socks and got fed up in a few weeks. I've tried the newer poly-something socks they gave us, and they weren't bad. The only problem was that they tended to stretch out over a few wearings (laundry opportunities can be few and far between here) and gave me blisters on long walking patrols. So, any advice? My feet are in your hands. Larry Somewhere hot, Iraq

Why display your ignorance on recumbent bikes? Everyone with first-hand experience on these now thinks of you as an ignorant fool. "Save your hate mail"? Well, quit displaying your obvious ignorance, basing your assessment on the experience of some third-party rider. And, if recumbents are really slower (according to your uninformed belief), how many upright bikes own land speed records? Have you seen many uprights hitting speeds of 81 mph on level terrain with no wind? I've only seen videos of recumbents doing that. Two of my six bikes are recumbents, so I know what I'm talking about. However, I don't own any airplanes, so I wouldn't try answering a question on airplanes. Bet you would. Brian Albuquerque, New Mexico

I seek your vast wisdom in selecting a small pack for the upcoming ski season; something comfy but lightweight that can pull double duty for lift-access skiing and limited backcountry use. I'd prefer a low profile pack under 1,800 cubic inches, with some sort of attachment point for skis as well as hydration-bladder compatibility. Also, do you think a panel loader would be better suited for this type of pack, thereby eliminating the need for a top pocket that might flop around when not completely filled? I asking for too much here? Joe Victor, New York

All I want for Christmas is a good headlp for winter use, but things have gotten complex. Voltage regulators, duo headlps, multiple settings, alkaline versus lithium batteries: these have all muddied what should have been a simple choice. Basically, what's the perfect headlp for an overnight or multi-day winter backpacking trip? Scott Maple Valley, Washington

I need some of your sage wisdom: As a pretty serious mountain biker and alpine skier looking to the approaching winter, I want to score a hard shell that will serve me both on the trails and the slopes. I've looked at Patagonia, Cloudveil, The North Face, and Lowe Alpine, but I'm lost in the many options. I want something that breathes well, keeps me dry in wet conditions. Insulation ain't important (got a great Patagonia fleece already). Please, point me in the right direction! Nathan Washington, D.C.

What do you think of the newer mountain bikes with 29-inch wheels? I'm thinking of upgrading my 1989 Fisher Hoo Koo E Koo for something more roadworthy, but that can still take the abuse of dirt trails. I was thinking of getting a cyclocross bike, but perhaps a 29-inch wheeler might be more suited to the kind of riding I want to do. Booker Kensington, California

These days it seems pretty much everybody's wearing bike helmets. Why can't you say the se for skiing helmets? And, do you think it'd be wise to shell out on a ski helmet? I've just booked up for a one-week ski trip to Colorado next February. Not having done much skiing before, I want to enjoy myself but also stay safe! Andrew Charlottesville, Virginia

I've seen quite a few hikers with two-way radios on the trail. What's your take: recreational gimmick or worthwhile piece of equipment? Our family of four hikes together a fair amount, so I can see their worth. But, then again, does trail etiquette mean this is akin to using a cell phone on the bus? Philip Burlington, Vermont

I recently completed a fantastic trip to Yellowstone and Glacier National Parks, but unfortunately my stove was confiscated by airport security on the way home. I'd emptied the stove and attempted to air it out, but still wasn't allowed to travel with it because I'd used it less than 24 hours beforehand. Can you recommend a method or product to clean out a stove that will completely eliminate any fuel odors and make it safe for air travel? Additionally, I'm now in the market for a new stove. I had a Peak-1 Apex II, reliable as the dawn though maybe a little heavy. Can you recommend a lighter yet equally reliable replacement? Dave Boston, Massachusetts

Every time I wake up in my new Marmot Swallow tent the condensation is so bad that my sleeping bag and clothes get wet, so much so that I'm considering taking the tent back and exchanging it for a Mountain Hardwear Skyview or MSR Fusion. I have searched the Internet and read many positive reviews about the Swallow, so is this just a common problem in three- to four-season tents, or did I just get the one defective tent in the batch?

Douglas Gantenbein, better known to many as the Gear Guy, has been hiking, biking, skiing, and climbing in Washington State and the West Coast for 25 years. During that time he’s endured leaking tents, back-breaking packs, balky stoves, and freeze-dried food so bad that even his always-hungry beagles would likely…

I own a long-sleeve Kodiak Light cycling jersey from Pearl Izumi. While nice, the jersey is too permeable to the wind, so I get chilled on colder days. Can I spray the front of the jersey's arms, shoulders, and chest with Scotchgard to improve its windproofing without trashing the piece? Or, is there some other spray-on product that would do the trick? D.J. Potomac, Maryland

I'm considering buying a recumbent bike for exercise on country roads, having had enough of the sore ass and shoulders I get when out riding my regular bike. What recommendations do you have about style and prices? Jerry Chpaign, Illinois

As an avid reader of your column, I knew I could come to you for advice. Does anyone make a waterproof backpack? I commute to work on my bike and need my stuff to stay dry. Specifically, I would really like to find a weatherproof pack that can carry my laptop. (And we get a lot of weather over here in Iceland.) I've seen courier bags from Timbuk2 and Chrome, but nothing really sings out to me. And, while we're at it, why doesn't anyone make a bag out of Gore-Tex XCR or something similar? Douglas Keflavík, Iceland

So, the winter snow will soon be upon us. As a snowboarder, my feet always seem to get extremely cold. I wear SmartWool socks, and I sometimes need to wear two pairs of socks (though not necessarily both SmartWool). Do you think my feet are just overly sensitive to the cold, or is there something else out there to keep my tootsies cozy?

I plan on doing some winter backpacking in New Hampshire's White Mountains for the first time. I need some help with sleeping bags—there are so many to choose from! Should I go for down or synthetic? What's a good temperature rating for this kind of trip? Mark Boston, Massachusetts

Fall's new casual boots feature a tried-and-true friend: durable leather. X-Ray 'em, however, and you'll find athletic-shoe cushioning and the sole and support of a hiker. Because you know what they say: real beauty is more than skin-deep.

Like travel itself, the latest gear for the road is full of wild surprises

I have some questions about a backpacking trip around India, where weight will be a consideration. We need a unit for recharging digital camera batteries (possibly with surge protection), as well as a lightweight but intimidating-looking lock and chain to secure our packs to seats and poles on trains. One more thing: I'm looking for a multi-climate sleeping-bag liner. Thanks much! Sue Boston, Massachusetts

Last year I bought a Specialized Sirrus Sport hybrid for road biking, with which I'm very happy. My brother's looking for a new bike, so how does something like the Marin ALP line of bikes, particularly their Highway One, stand up against the likes of my Specialized Sirrus? A bike mechanic told me that Marin's star is waning, and that you are paying for their ne. Thanks for your insight. I've actually set up my Internet browser to open your column as my personal homepage, and have used your advice more times than I can remember! Patrick Chicago, Illinois

So everyone I know agrees the Marmot Oracle is a fantastic storm protection jacket. But sometimes you have to take the advice of longtime friends... and throw it away because they are not the Gear Guy. I want an ultralight jacket to throw in my pack while hiking. I bought my wife the Marmot Oracle, which she loves, but what do you think about products using PacLite such as the GoLite Phantom Jacket, or the Marmot Osprey? I already have an Arc'teryx Beta AR, but is that light enough, or would PacLite be worth it? Jeremiah Eugene, Oregon

Now that the venerable Patagonia Ice Nine ski bibs have been discontinued, what do you recommend in their place? I want something similar: waterproof-breathable, light but durable, great features. However, I've read not very complimentary things about The North Face's Gore-Tex XCR bibs. Richard Oak Ridge, Tennessee

Which do you think would be better for a backcountry winter camping trip in Yosemite: snowshoes or a ski like the Karhu Morph (which looks like L.L. Bean's Boreal and features a built-in climbing skin)? Tom Marina del Rey, California

I planning a climbing trip to the Yosemite Valley in a few weeks, and I was wondering if you have any recommendations for a hydration pack I could use while climbing. I would use it to also carry a small headlp, rainjacket, and a few energy bars. I looking for something low profile that will not get in my way while climbing. Anything fit the bill? Alan Locust, New Jersey

Lieber Ausrüstungmensch: Looking at the change of seasons and your report on the latest and greatest in the gear world, I'm trying to come up with a clothing strategy that maximizes economy of budget and weight. I'm a keen hiker currently living in Germany (near the Alps), but who will be moving back to the East Coast of the U.S. (Smoky Mountains!) soon. I want a system that will cover me when it's warm, cool, and wet. Should I go with a fleece-plus-shell combo, lugging around the deadweight when I'm not using it, or should I buy one of the do-it-all soft shells? Patrick Frankfurt Main, Germany

I do quite a lot of bushwalking in the Japan Alps and have been carrying my Canon SLR with standard lens, and occasionally an extra telephoto lens—all told, a hefty load. I'm not such a serious photographer to need all that extra weight, but I would like better photos than a disposable or compact can produce. After some research I had decided to splurge on a Contax T3, but then I saw a new Pentax SLR—the "*ist"—that weighs only 335 grs (presumably that's the body only). So, with a matching lens, it still comes in at about half the weight of my current camera. I presume the optics are plastic, hence the low weight. Which would you choose? Excellent fixed lens or zoomable plastic? Dian Tokyo, Japan

For the last five years, I've been lugging around a seven-pound Dana Design Stillwater pack. But recently, I've seen the "light" and have gone lightweight. Can you recommend a solid, 4,000-cubic-inch pack that weighs less than four pounds? I was looking at the Osprey Aether 60 and the Mountainsmith Auspex, but which would you recommend? Thanks for always being the "go to" guy when it comes to gear. Jake Irvine, California

If a guy was headed to Denali in May, and asked you to compare the Marmot 8000 Meter Parka with the Feathered Friends Rock & Ice Parka that you used, what would you say? And, since I very good-looking, would you like to use my photo at the head of your column and tell people it was you? Bob Reno, Nevada

Dear Gear Guru, I'm thinking about bringing my Labrador camping with me, but don't know if he needs special gear. I have a two-person tent, and there's no way my wife and I could fit him in there with us. I don't think he'll be satisfied sleeping in the tent's vestibule either. What should we do to make sure he's happy and safe? John Bloomington, Indiana

During a week's hiking around the High Sierra Cps of Yosemite, my backpack began to reek! Even though I washed myself and my clothes regularly, my husband, who is normally a very sweet man, insisted I hike behind him so as not to be asphyxiated. How, oh how do I get the stench out of my backpack straps?

What's the deal with "fly-only pitching" options with tents? My partner wants a roomy, comfortable double-wall tent for two (she likes The North Face's Roadrunner 2). However, I also want a lightweight single-wall tent that's easy to pitch for solo camping and just traveling light (something like a Bibler Megid or GoLite Den 2). Will a tent with fly-only pitching meet both needs? Jes Sydney, Australia

I recently completed a two-week, 96-mile trek in Alaska's Brooks Range. I thought that I was traveling as light as possible until I encountered a couple of wandering hikers who were carrying external-fre backpacks fashioned with titanium fres and Kevlar fabric. Their packs, from Cp Trails, weighed at least half of my Longbed pack, and mine was smaller. After returning to civilization I immediately visited the store where they told me such packs could be purchased, but the sales staff gave me that "what planet are you from?" look upon hearing my tale. Assuming they are the ones from another planet, can you help me find a super-lightweight pack weighing less than four-and-a-half pounds, with up to 6,500 cubic inches of capacity? Is there such a creature still being made out there? Fred Kodiak, Alaska

I'm headed to the Okavango Delta in Botswana for six months through a job with Conservation International. I not a very experienced photographer, so can you recommend a reasonably priced camera that'll take great wildlife photos? Todd Baltimore, Maryland

I have a medical condition known as Raynaud's, which basically means that I have real problems staying warm in temperatures below 50 degrees. This past winter was a killer for me. Unfortunately I can't hole up inside during the winter as my 100-pound insulated dog needs to walk (and loves the cold). What do you think would work best for me? I assume down, but the women's down parkas don't seem to be that warm. Faith Reston, Virginia

What does one do when his hero lets him down? Last fall you spoke highly of the St. Moritz Pathfinder TI watch. Well, let me tell you, the Gear Guy is fallible. This watch has been a huge letdown. The "glow factor" of the numbers is terrible, the alarm is barely audible, and the service is less than acceptable. I sent it in for warranty repair for its water resistance, being sure to mention the other factors, and the service was very slow and they never even addressed my other concerns. I think you may have made an error! (I know, hard to believe.) Tim Moose, Wyoming

Thanks for asking the Gear Guy a question. Stay tuned to the Gear Guy’s column for your answer. He should get back to you in about a week. Of course, while he’d love to answer everyone’s questions, he’s so busy testing equipment that he…

I was rock climbing in Australia earlier this year when I fell and wrecked a lumbar disc. I'm having surgery to decompress the spinal nerve in a couple of weeks (a lumbar microdiscectomy), and I'm itching to get back into trping (you call this "hiking") and climbing and so on. Since physiotherapists don't know much about backpacks, I'm wondering if you can help me: Is there a backpack that is better for your back (i.e., one that doesn't compress your lower back too much)? I currently use a fairly simple 60-liter New Zealand-made pack by Cactus Climbing. Karen Wellington, New Zealand

My husband and I are having an argument about our 20-year-old down sleeping bags. The bags in question are Blacks Icecap XL mummy bags. I've recently being doing some fall camping and find that I get quite cold some nights, leading me to surmise that these sleeping bags have reached the end of their days. My husband says it's just my age, as he doesn't find them cold. Now I know I shouldn't bother arguing with him and just go out and buy myself a new sleeping bag, but I want you to tell him that down sleeping bags do "die" eventually. Can you back me up? Carol Port Moody, British Columbia

In one of your long-ago columns, you gave the scoop on the well-known Cascade Designs Chair Kit and the Therm-a-Rest Chair Lounger. But in the spirit of "discovering" unknown, neglected products, does the Gear Guy have a take on the Sling-light chair (naturally, at slinglight.com)? Does this alternative, lightweight product deserve our consideration? Marshall Atlanta, Georgia

I have been searching for a backpack for extended trips, and it seems like all the local shops vacillate between Osprey and Dana Design packs. If you were going to buy a pack today, would you buy an Osprey Crescent or Dana Design Glacier? If so, why? Matt Albuquerque, New Mexico

I recently bought a secondhand Osprey backpack. Every time I use it and break a sweat, I'm overwhelmed with odorous memories of someone I've never met. Is there a way to rid the suspension of the previous owner's "scent"? Stan Gainesville, Missouri

All-knowing Gear Guru, I intrigued by Dana Gleason's concept of separating a backpack's suspension and pack into two separate components. Is this idea worthwhile? Also, Kelty is "the first licensee" of Gleason's Mystery Ranch System, and Kelty's line is significantly cheaper. Is there any difference? Dion San Francisco, California

I have Scarpa T1 boots and have noticed that my ski edges are going to massacre my boots if I don't protect them. A solution I have heard of is to wear "supergaiters" with either Kevlar or other sturdy material on the instep to protect the inside of the boots. Unfortunately Black Diond (she on them) no longer makes a supergaiter and the Outdoor Research X-Gaiter is overkill in that it is expensive and so insulated that it will cook my feet. Any advise? Bill Hirshberg New York, New York

I'm staring down the barrel of a long, cold, wet winter, which will put a crimp on my outdoor bicycling. Now, I can't afford a house big enough to install a velodrome, so I'll need to purchase either a trainer or rollers to ride my bike inside. Should I fear the rollers? Will I need to put fo padding all around them? Will true believers mock me if I buy a trainer instead? Glen Novato, California

Oh, Gauis Gear Guy (bet you haven't heard THAT one before), I have a multitudinous problem. I wrote to you years ago about detached toenails, and you delivered the goods shiningly. My problem is still with my feet. The last two trips I've taken in my Zberlans boots have left me hobbled, with huge Susan B. Anthony pus-bubbles on either heel. I went to a clinic and was informed that my feet were "problematic" and that I was wearing the wrong boot. My right foot while standing is about a quarter inch longer than the left. My feet are wide and low profile, with anemic arches and narrow heels. Oh yeah, I also have weak ankles. Now I have June trips planned in the Grand Canyon and the Sierra. I've bought the Superfeet shrink-to-your-dogs prosthetic insoles, but I need a new boot. What do you recommend, outside of foot-transplant surgery? Thanks, Thomas Perkins Alexandria, Virginia

Your Gearness, I planning to drive cross-country this summer, hiking and camping wherever the road takes me. For the driving portion, I was thinking of investing in a GPS system to help with the "figuring-out-where-the-heck-I-am" moments. Do you have any advice as to the value of GPS for this? (I will not need it for hiking, using the old-fashioned technique of map, compass, and trail blazes) Realistically, I'd like to stay under $300, but will go higher for an exceptional device—one that does the navigating, driving, AND laundry. Charles New York City, New York

Oh Great Gear Voice of the Heavens, What's a nice, dry, two-person, three-season tent with two doors and vestibules? My current tent is a Sierra Designs Orion AST. It's a very well built tent and stayed completely dry in a very wet trip to Deer Lake in Olympic National Park. I like being able to use only the rain fly and ground sheet as well as the window in the fly. The problem is that the very slanted door lets stuff collect in the tent entrance and makes zipping and unzipping tough. It also makes the vestibule useless for anything but boots. I hope to get a new tent with two doors that are straight up and down, but don't want to lose the high quality and rain-proofness. I willing to give up a little in weight if I could get a ground sheet that covers the floors of the vestibule as well. Chris Barnes Bremerton, Washington

I've been skiing for years and haven't needed to buy new thermal underwear in a long time. But now that I'm ready to replace it, several new materials are on the market. I know I don't want cotton, but what about silk? Wool? Or should I just stick with polyester? y Kuntz California

I'm looking for a mountaineering boot for tackling some of the Lower 48's fourteeners. I've reviewed the Koflach Degre and the Asolo Guide, but I'm also interested in some of the newer leather boots, like the Scarpa Cerro Torre Thermo. Have the new insulated leathers finally become an acceptable solution, or should I stick with doubles? Matt San Ron, California

Are candle lanterns safe to use in tents for light? Obviously you'd want to keep an open fle away from the tent walls, but are they as safe as a battery-powered lantern? John Bergquist Corvallis, Oregon

I'm 55 and like to ride bikes. Here near Lake Michigan in late spring, it's often sunny and cool. I see a lot of die-hard bikers wearing tights, but I'm not interested...is there anything else I can wear? I tried tennis warm-ups, but they're too slippery on the bike seat. Stu Highland Park, Illinois

What's the best crampon for the LaSportiva K3 boot? Can I use semi-rigid crampons with them to climb vertical ice? I need crampons for that and glacier approaches but am afraid that if I get a fully rigid crampon I will get to much balling-up effect with the snow. Joe Roop Prescott, Arizona

I have a 15-year-old Peak 1 stove that still works great. I was wondering if I could use cheaper unleaded gasoline (about half the price of Coleman fuel) without blowing me or my friends up. Or do I need to get a newer model made for both white gas and gasoline? J. D. Craft Lancaster, Ohio

I have a simple question. I dried my jacket on a high temperature in the dryer. Everybody tells me I shouldn't have done this, but how will it affect my jacket? Adrien Lancaster, United Kingdom

G'day Gear Guru, I've noticed a couple of innovative water-purifiers that incorporate the filter mechanism directly into the cap of a light, convenient, and squeezable water bottle. Models by Orinoco and SafeWater Anywhere make lofty claims of filtering and purifying the nasties better than traditional pump-style filters; the SafeWater model even has a filter cap that fits onto Nalgene bottles. Is there any point to lugging around our old pump filters anymore? Lange Sydney, Australia

Oh Gear Oracle, I have a problem with a build-up of moisture within my mittens, not from rain or snow, but from my own perspiration. This is especially true during snowshoeing trips. I was wondering if there are any shells that have little or no insulation, allowing me to layer them inside and increase the breathability of the mitten. Dennis Portsmouth, New Hampshire

Oh Gear Guide, you have failed us! Over and over I have heard you espouse the quality of the Yashica, so I decided that the T4 was the camera for me. Unfortunately, after hours of searching, I find out that the T4 has not been made for years! Just recently, you suggested the camera but didn't mention that it would be impossible to find. With the T4 no longer on the market, what kind of camera would you suggest? Mike Newark, Ohio

At what point, if ever, should your boots be replaced? Is it a question of mileage, time, or condition? I've had my boots (L.L. Bean Knife Edge, leather) for a number of years. They are well maintained and comfortable. Is there a point where the boot does not perform its support function and the trade off between comfort and support (in favor of comfort) is not worth it? Jim Comerford Wyncote, Pennsylvania

Your Gearness, I'm in desperate need of your expert advice. After two major knee surgeries involving saws, metal plates, and screws, I have suddenly become an advocate of trekking poles. I own a set of Master Kompressor poles with comfortable handles and a useful shock-absorber option. However, I've been tempted by a pair of Leki Ultralites, which are six ounces lighter but without the shock absorbers. At five-foot-one and about 120 pounds, do I really need poles with shock absorbers, or is it a waste of money for me? I have my sights set on the Grand Canyon this spring and would like to have time to "road test" a set of poles before then. Paula San Diego, California
