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

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

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

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…

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

Can you recommend a lightweight digital camera for backpacking? I was ready to purchase the Yashica T4 that you talk so highly of, but digital cameras are so compact and I don't need to carry all that film. Also do they make water-resistant digital cameras? Dan Hearty, Missouri

I looking into buying a soft-shell jacket and interested in the Cloudveil Serendipity, the Arc'teryx Gma, and another jacket from Salomon. What are your opinions on these jackets and are there any others that I should consider? Mike Kane Rock Island, Illinois

My girlfriend has had problems finding a boot for her narrow foot. In particular every boot she has tried so far has caused blisters on her heels due to slippage. Can you suggest a backpacking/hiking boot for women with narrow heels? Jon Rauer Charleston, West Virginia

I have an opportunity to buy a Tempest 23 tent from The North Face (retail $675) for $400. It is brand new and it looks bombproof. I have asked all over and searched the net for info about this tent and have come up empty. I heading to Mount Shasta in June and would like a good mountaineering tent. On the other hand, I also need to upgrade my old duct-taped, three-season tent. I not sure what to do, buy this single-wall tent and buy a good three-season, or look into a convertible tent. I don't want to miss out on a good deal. Brian Holt Detroit, Michigan

Do you have any recommendations for headlamps? I'm a casual camper intrigued by the new LED lights. The battery-/bulb-life is amazing, but are they bright enough to be worth the purchase? Michael J Ogden, Utah

I planning a trip to Belize this spring. I own a MSR Superfly and have already used it many times. Can I bring the stove—minus fuel canisters—on an airplane? I really don't want to purchase another stove. Brett Skraban Chicago, Illinois

I preparing to go on a seven-day backwoods trip to Glacier National Park, and I'm trying to determine what stove to use. As I like white gas (I have an old Optimus), how much fuel do I need if I'm cooking three times a day? I will probably upgrade to a Simmerlite or possibly a Zip Stove depending on your answer. John Cden, Maine

What's a good trail-running/adventure-racing shoe for an over-pronating runner like myself? I need to buy a new pair of shoes quickly! Rob Indianapolis, Indiana

My trusty 35-year-old Svea stove is in need of a new gasket for the cap. I've made one, but the material I used is too hard to effect a good seal. Is the real thing still available? I also need the cleaning needle. Is that available? Kent Tracy, California

In September I'm headed to a lodge in the stey Amazonian rainforest, so I'm looking for a poncho or raincoat that will be light, packable, waterproof, breathable, and cool. But everything I've looked at so far has liners and seems more suited for warmth in mountain winds than for a humid rainforest. What's my best bet to stay both dry and cool? Patrick Jonesboro, Arkansas

I need a waterproof tent. I spend most of my time outdoors in fall and winter, and two REI tents and one from The North Face have failed me. The problem isn't water coming in through the ses; it is coming through the fabric itself, including the rain fly. I've even tried, unsuccessfully, to spread silicone caulk on the rain fly. Can you recommend a tent that will stay dry even if a fire hose is turned on it? Jeff Moscow, Idaho

I recently saw The Seat from ERGO, LLC advertised. The makers claim that this seat does away with numb-butt syndrome and sexual dysfunction (real important). Can you confirm or deny these assertions? Dennis Hilton, New York

I'm looking to buy a fly-fishing rod for some of the smaller Rocky Mountain stres. Any suggestions on where I can get a decent rod that will break into small packable pieces? Matt Albuquerque, New Mexico

How can Limmer and other high-quality boot manufacturers send your boots to you sight-unseen, without ever seeing your "dogs," let alone sizing them? Jim Coeur d'Alene, Idaho

I contemplating through-hiking the Pacific Coast Trail, Continental Divide Trail, and Appalachian Trail in succession and need info on the packs made by GoLite (based on Ray Jardine's designs) and Wild Things, and the tents by Warmlite. I have not had the opportunity to test any of this ultralight gear. I know you have answered before about the philosophy behind the "Ray Way," but I after actual gear tests of these products. I feel GoLite's packs (the Gust or Earth for me) would be high quality but haven't heard anything about them. The Wild Things AT may give the Earth or Gust a good fight but the price is higher. Any thoughts as always would be absorbed and contemplated. Scott Running Springs, California

What's the best handheld altimeter for mountaineering? I have looked at the Suunto, Brunton, and Thommen models, but not sure which has the best features for high-altitude Alaskan climbing? Ron Toronto, Ontario

Checking out this season's gear, it's clear outdoor clothing is becoming truly high-tech; we can travel lighter and more comfortably than at any time in history. To tell the truth, I feel kinda sissy not having to grin and bear the cold and wet anymore. Are we reaching a point where technology only offers incremental returns beyond what it can do today? Will we ever see paper-thin insulating jackets, or do the laws of physics prevent a future of sci-fi outdoor clothing? Ross Reading, California

How do I get the nasty smell out of my old footwear? I like to buy quality boots and shoes that will last a long time, but inevitably, long before they are worn out, they start to stink (my feet tend to sweat a lot). Any suggestions as to removing the offensive odors and bringing these old friends back into service? Bill Charlottesville, Virginia

I currently own a pair of Tecnica backpacking boots that should be well broken in after 200-plus miles of use. However unless I pre-treat my heals with second skin, I end up getting heal blisters. I think this maybe due to my high foot bridge and the boot's lacing system. Any recommendation on a boot that might work better for me? No Name Given

After straining our eyes for years (and believe me, the years have gotten to me) my wife and I have decided to consider a spotting scope for our field trips. I new to scopes and confused at to the benefits between a straight versus angled lens and as to what optical power is most beneficial for nature viewing. Can you recommend a few bombproof spotting scopes (we take our fair share of spills and falls on the trail) with quality optics to view and appreciate nature with. Mr. Magoo Galveston, Texas

I need to buy a pair of boots that will work well on Mount Rainer and Mount McKinley. They need to be waterproof and crampon compatible. I don't need them to be overly heavy but they have to keep frostbite away in a storm. What are some options for both plastic and leather boots? Jeremy

Are soft shells for real, and can they adequately replace a 300-weight fleece as an insulating layer for mountaineering? Would they give me the benefits of a windproof, waterproof, and breathable layer before the hard shell is donned when the weather gets really nasty? Matt San Ron, California

What's the deal with siliconized nylon? Smaller companies like Integral Designs, Six Moon Designs, and Wanderlust Outdoor Gear are making extraordinarily light tents and tarps out of this stuff, yet the Sierra Designs and Mountain Hardwears of the world aren't using it. I understand it doesn't breathe well and thus condensation can be a problem, but is that a big deal? In other words, what are the arguments for not using it? Kevin Larkin Blacksburg, Virginia

I in urgent need of a warm sleeping bag for use on an upcoming desert running race I entered in, the Marathon des Sables in Morocco. Although this conjures up visions of heat and sleeping under wispy silk fabric whilst warm winds blow, the reality is that at night, temperatures can plummet to freezing. I'm not too concerned about cost and need a bag which is at least good for about 32 degrees, and most importantly, LIGHT!! It has to be carried and raced with for over seven days. Please recommend waterproof varieties or appropriate techniques as it can pour. Dio Wong Hong Kong, China

My summer bag is an Integral Designs Andromeda Strain (40-degree, Primaloft); my three-season sack is the North Face Cat's Meow (20-degree, Polarguard Delta). Both are sweet bags. My question: can these bags be combined (summer bag inside three-season bag) to make a winter bag? Will I gain much, or will the inside bag be unable to loft up and therefore not provide much additional benefit? Thanks! Bill Stell Charlottesville, Virginia

I was thinking about combining my expandable Mountain Hardwear Galaxy SL sleeping bag with the maker's 40-degree Down Upgrade bag. What do you think about combining these two sleeping bags for a Denali summit attempt? Rob Boston, Massachusetts

I want to buy some new cross-country skis that I can use for both touring and downhill, maybe something along the lines of the Karhu Catounts. While these seem to work well for touring on ungroomed trails, would these also suit for telemarking on blue-square trails? Rusty Cresco, Pennsylvania

Can you recommend a good cross-country skiing package that's suitable for both groomed trails and backcountry use? John Duluth, Minnesota

I looking to purchase a pair of snowshoes and wondering what length/style I should get. I'm five-foot, 11-inchess tall, and weigh about 180 pounds. I most likely will be using the shoes primarily for day hikes so I would probably be wearing a daypack and possibly carrying my skis. Scott Garvin Boston, Massachusetts

From what I've read, your gear reviews are right-on, so I seek your help finding a hydration pack that can hold ultralight gear for overnighters, as well as up to 100 ounces of water. I hope to use such a pack for mountain biking treks as well, so it'll need to have a tight fit and good suspension system. It's proving difficult to find something to meet all these needs, although I noticed you recommended the Ultimate Direction SpeeDemon to a trail runner in January 2003. Is this pack suitable for mountain biking? What about other possibilities like the Ultimate Direction WarpSpeed or the CelBak Peak Bagger? Todd Alpharetta, Georgia

I'm planning to do some solo hiking this summer and would like to take along more than a bivy bag for shelter. I'm looking for a three-season tent that maximizes room (I'm six-feet tall) and minimizes weight. Perhaps a Walrus Microswift or the Sierra Designs Ultra Light Year? I'm not finding too much information or many reviews on the Net, and those that I do find are outdated. Any advice? Don Sherwood Park, Alberta

My girlfriend is hoping to go on a ten-day wilderness orientation trip for UC Santa Cruz put on by Outward Bound. The problem is that she has a bulging disk in her lower back. The sports medicine doc she's seeing says that she should be OK, but I'm not so sure. What are your recommendations for a pack? External-fre packs put more of the load over your hips, right? (She's five feet, three inches and weighs about 100 pounds) Colin Wood Colfax, California

Dear Gear Guy, can I extend the life of running shoes by using Dr. Scholl's gel insoles? Will they improve the comfort of hiking boots? By the way, I use orthotics. Gary Goins Denver, CO

What types of materials in gaiters are best for snake protection? I know of Teflon, but is a heavy canvas also suitable? (If you're wondering how my question has any relation to where I'm from, it doesn't. I'm moving to Australia.)—Karen, Vancouver, British Columbia

I'm wondering if you know the difference between all the soft-shell fabrics, specifically Power Shield and Schoeller Dryskin. Also, what's the deal with the ultralight rain shells like Patagonia's Microburst or Arc'Teryx's Sirrus SL? REI's Web site used to say that Sirrus SL is "truly an ultralight shell, thus should not be for everyday use." Are they suggesting the ultralight jackets are not that durable? Does it make sense to carry both a soft-shell and an ultralight rain shell on a long backpacking trip? Jenny San Diego, California

I'm looking for a good underwater and above-water digital camera. Any suggestions for what I should look for? Margaret Hilo, Hawaii

Are there any materials that can offer reasonable rain protection and still breathe well? I can't use Gore-Tex in anything but the coldest conditions without getting significantly dp. How does REI's Elements line stack up? Ken Johnson Hollister, California

I'm going hiking on the West Coast Trail and I have boots with Vibr soles. They are very slick on wood in wet weather. Since it constantly rains on the West Coast and you have to traverse many wooden bridges, ladders etc., I was wondering if you could suggest a boot with a more water-friendly sole. Dan Anstey Ottawa, Ontario

What is the stiffest material that a road-racing bike can be made of? Also, what's a good compromise between a really stiff bike and a really light bike? Justin Seattle, Washington

Oh Gear God, I've eschewed "wind-blocking" fleece over the years in the belief that something like Marmot's Driclime Windshirt is more efficient. But then I went to Patagonia and discovered their oh-so-tempting R4 jacket. Of course, having disdained wind-blocking fleece for so long, I know nothing of the advantages and disadvantages of Gore Windstopper, Polartec Windbloc, and Windbloc-ACT. Can you enlighten me? And, while you're at it, do you think the ever-so pricey Patagonia version is worth the extra dough? Finally, is it gilding the lily to put a windbreaker over one of these wind-blocking whatchacallits to keep them dry in a light rain? Mark San Francisco, California

Tent versus tarp? Scott Gillette San Jose, California

My wife and I are looking for a canoe, to use mainly during weeklong trips on flattish water: something sturdy enough for rocks and beaver ds, yet light enough for long portages; large enough to carry our packs, yet small enough to be nimble in narrow creeks; stable in wavy conditions without feeling as though we're paddling a tugboat. Can you help us navigate these compromises and suggest some good all-round tripping canoes? Rob Calgary, Alberta

Can you recommend some easy ways to reduce condensation inside a tent? In what sort of conditions should I expect the most condensation? Carter Virginia

OK, call me a masochist, but I love winter camping. However, when I try to convince some members of my family to go with me, the answer is always the same: "Too cold." So I spy the Zodi Hot Vent II ($135), which uses a propane cylinder to provide heat to the tent. This could be just the ticket! But does it work, and is it safe? Only the great Gear Guru knows for sure. Jeff Minneapolis, Minnesota

Up until now, I've been content with either picking a wilderness that allows backcountry campfires for cooking dinner, or eating cold food for the duration. Now I'm starting to feel like my choices are limited and/or my dinner sucks. What kind of backcountry stove should I be looking into, and what is the difference between the different fuels? For the stove, my most important prerequisites are that it's lightweight and reliable. Mark Brick, New Jersey

What's the advantage of wearing mountain bike-style shoes with pedal clips, versus regular, all terrain-type shoes? Also, how does one escape from the clip? Jes Greene, New York

My wife's extremities get very cold on winter backpacking and ice climbing trips. I'd like to get something to help her out. I was looking specifically at the Moonstone Sauvage Glove. Any other recommendations? Chris Ralph Mountain View, California

Oh Great Gear Guru, I have a simple question. I recently ce across "directional clothing" by a manufacturer called Paro. Have you heard of it, and more to the point, have you had the opportunity to try it out and rate it? I would like your opinion on this stuff. Andrew London, England

During the winter I run in the early morning hours when it's dark and cold. What do you recommend for a good reflective winter running outfit? Lance Delafield, Wisconsin

We recently acquired a German shorthaired pointer who loves to swim in the ocean—not just play around in the surf, but really get out there and swim past the waves. Trouble is that with her short hair, she is freezing cold before she's tired out. We'd like to purchase a "doggie wetsuit," so to speak. Since we live in the self-proclaimed surf capital of the world, it seems a logical idea. Should we purchase one of those hunting-dog neoprene vests? Or are we just acting like overly-protective, wussy Californian dog owners? Thanks for not laughing too hard. Deb Encinitas, California

My husband and I are neophyte campers who need a tent that is reasonably priced, waterproof (Florida's thunderstorms are sudden and legendary), roomy, well ventilated (humidity here reaches 99 percent most of the year), and useful for both forest and beachside camping. Did I mention that we have only $150 to spend? Lynn Orlando, Florida

With "just in case" in mind, I like to pack extra food when preparing for a day hike. Pound for pound and calorie for calorie, what's the best emergency trail food? Carrol Phoenix, Arizona

In case I get a big heel blister, what should I pack in my first-aid kit? Charity San Diego, California

My 1994 old-school Nishiki Backroads has no suspension and I'm starting to weekend-warrior on single-track off-road. Should I upgrade components on the existing fre, or go new with a hardtail or dual-suspension bike? My budget is less than $1,000. Marc Richardson Oakland, California

Could you please tell me what you figure the efficiency of slicks versus knobby biking tires is? A local dealer says it is insignificant, and I figure it is ten to 15 percent. Bill Invermere, British Columbia

Any recommendations for a two-person backpacking tent big enough for a six-foot, five-inch, 250-pound camper? I already have a Sierra Designs Clip Flashlight two and it seems a bit small for just one person (me), especially after more than two nights of foul weather. Jim McGowan Charlotte, North Carolina

I'm planning on hiking Vermont's LT, and because of past knee problems I'm trying to pack as light as possible. I've been considering buying the Mountain Hardwear Phantom sleeping bag, but I'm concerned about its down fill. Any thoughts? How effective is the water-resistant coating used on the superlight bags? Neil Westport, Connecticut

I am looking for a tent that will repel dew, especially as I hate the damp feeling that comes from wet grass. Which tent do you recommend? I don't do much camping, but I do like to be comfortable when I do. Tara Bowler, Wisconsin

Are there poles that could do double duty for downhill skiing and trekking? Or is that too much to ask from a set of poles for around $100? Dan Pittsburgh, Pennsylvania

My family of five—myself, wife, and three decent-sized kids—plus the dog would like to go snow camping, and I think I've got everything covered except the tent. As for cost, we'd prefer to be comfortable and broke over rich, frozen, and miserable. Unfortunately, I can't seem to find a suitable five-person tent—MSR's StormKing comes close, but only allows 12 square feet per person. I have concerns about splitting the family into two tents in potentially nasty weather. Do you have any advice? Nathaniel Nevada City, California

What's a good internal-fre backpack for someone just getting into backpacking (two- to four-night trips)? I don't want to spend more than I need to, not knowing how much I'll end up liking backpacking. (I've strictly been a day hiker in the past.) However, I don't want to buy junk that won't work properly and will ruin my trip. Kris Newbury, Ohio

What is the best hat for summer backpacking? Cotton baseball hats are too hot, too sweaty; synthetic caps are a little cooler. But how about a straw hat? In particular, the L.L. Bean Summer Straw Hat that supposedly folds up and packs easily? By the way, your reviews are probably more useful and readable than all the others. Congratulations, and thanks! Marshall Atlanta, Georgia

I'm in need of a bigger climbing backpack, but I'm facing two problems. First, I also need a bigger backpack for weeklong trips; my climbing partner says just get one huge bag, just don't fill it up. So, one bag or two? Second, how big? I a five-foot-six, 130-pound female, and I think I require at least 3,000 cubic inches for my climbing needs. Kendra Boise, Idaho

I've been moving slowly into the lightweight crowd and trying to get my week-long, summertime load below 30 pounds (I live in the Midwest, so a good portion of that is DEET!). I can make it, except for the pack itself. Are there any good lightweight packs? Is this a good place to save weight? Most that I've tried may weigh less, but they make the load seem heavier to me. Tim Taylor South Bend, Indiana

What's the best audio device that I can clip onto a pair of shorts when running and doing other multisport activities? Ceron Christchurch, New Zealand

Any idea where I might look for prescription sunglasses that I could use at high altitude? My local optician says the lenses he could sell me "might" block both ultraviolet (UV) and infrared (IR) rays, but he's not sure. Is blocking both UV and IR really important? Andy Billings, Montana

I have been looking for a three-season alternative to my mountain tent, which has proven bulletproof for backpacking and climbing expeditions in mild conditions. The North Face Tadpole 23 seems to be a lightweight, good-looking choice, and since it's from The North Face, I have no questions on quality. What do you think? Christian San Diego, California

I bought a pair of leather Scarpa hiking boots, but I'm having trouble breaking them in. The soles feel too rigid and it hurts to wear them, even for a short hike. I think they are too sturdy for my weight of 116 pounds. Some people have told me to get them wet and then hike in them. What do you suggest? Janet Payson, Arizona

You have mentioned in the past that you are lukewarm on single-wall tents as in some circumstances they are neither as warm (winter) or as cool (summer) as double-wall tents, and prone to condensation issues. But you have also recommended the single-wall Bibler Ahwahnee, especially when weight is an important factor. I'm also curious if single-wall tents make a similar two-way compromise to that of modern membrane clothing—neither letting perspiration out perfectly nor keeping very heavy rain out perfectly. You have mentioned half of the clothing equation as an issue with single-wall tents. What about the second half—do they also leak in very heavy rain? Stephen Piper Alexandria, Virginia

I'm trying to decide whether or not to shell out on a bunch of new equipment for a scuba diving course in Turkey this summer. What does the all-knowing Gear Guy say: buy all and be ready before I go, or rent equipment once I'm there? Grant Washington, D.C.

Can you wash waterproof gear? I was taught long ago that when I come home from a camping trip, I should wash and air out my tent and backpack, wash my sleeping bag, and wash the dust and grime off my boots (I usually wax them, too). That way the items would last longer. My boyfriend, on the other hand, thinks that washing things like waterproof gear, his bike trailer bag, or even his CelBak will "ruin" the waterproofing. As a result, his gear is smelly and dirty and I don't want to share it. Miriam Boise, Idaho

I have read that wool clothing is better than any synthetics made. Is that true? Smartwool is coming out with a 5.2-ounce lightweight shirt in August-could this be possibly the best shirt out there for backcountry travelers? Also, is there a pair of lightweight pants that perform well in a wide range of climates? I would prefer convertibles, but regular pants are okay as long as they breathe well. Peter Portola Valley, California
