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 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

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

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 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

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

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

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

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

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

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?

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

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

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 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

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

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

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 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

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

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

You've helped me choose backpacking and mountaineering gear in the past and I'm counting on you again. I'm set to shop for a kayak this spring, and want some advice. My plans call for mostly day trips with some two- to three-night trips on mostly flat rivers, never more than class II/class II+ whitewater. I want a comfortable boat that tracks well, is maneuverable for those class II stretches, and that can hold me (six feet, 210 pounds) and my gear for those three-day trips. I'm thinking a boat in the 12-foot range. I'm hooked on Wilderness Systems Phase 3 seating, but open to suggestions Mike Baltimore, Maryland

A couple years ago I bought a Condor tent from The North Face, being informed by the salesperson that it was a four-season tent, although I have since discovered that may not be the case. I planning a June mountaineering course in the North Cascades that requires a four-season tent. Will my TNF tent suffice? I haven't used it for a while and lost the instructions, so do you know how I can contact them? Russ Frostburg, Maryland

I do much of my hiking in northern California's poison oak-covered hills. Usually I can avoid getting oaked, but after a day of tromping through this toxic weed, just how long do its oils remain active on my boots, gaiters, and trekking poles? Has science determined a half-life for poison oak's poison? Carter Napa, California

I use a 1968 Pinarello road bike. So, I was on a nice ride when I heard this "boing" noise; before I knew it, the derailleur (I think it was the original) had tangled in the wheel. The derailleur is now in two pieces, so I need to replace it. Are there any brands or models you could recommend? Can I put new gears on such an old bike? Could this have been prevented? Anthony Green Bay, Wisconsin

I thinking of upgrading my steel fre road bike to a carbon fork. I have tried a carbon fork in the past, and found it to be somewhat unsteady at high-speed (40 plus mph) descents. I weigh 185 pounds-does weight have a lot to do with the choice of a fork? Any suggestions? Should I just save the money and stay with my tried-and-true steel fork? Steve Weinberger Spokane, Washington

I've been doing some research on altimeter watches and have come across a lot of bad reviews for watches that I thought were good. Which watch would you recommend between the Casio Triple Sensor Pathfinder, the Timex Helix Works, and the Suunto Vector (some guy told me the workmanship on this was terrible and it fell apart)? Nadav Jerusalem, Israel

Are there any one-person tents that you can combine to make into a two-person tent? Denise Centennial, Colorado

In search of the Golden Boot over the years, I've owned disappointing Danners, Limmer mid-weights that ate up my right heel, and a forgettable pair of Meridians. I have a fairly low-volume foot, and while my current boots—a pair of Vasque Sundowners (Gore-Tex old style)—work pretty well, my feet still get hot spots and ache after a 12-mile walk. What's the boot for me? Stephen Decatur, Alabama

I'd like to invest in a pair of waterproof-breathable pants for one- or two-week treks where I might encounter rain and snow. Ideally, the pants would not be too bulky as they might spend quite some time in my backpack (I hope). If possible, please note any brands that I can find in Europe! Nicolas Heverlee, Belgium

My Boy Scout troop is planning to buy some rappelling gear, but we need some advice first. Eric Shelbyville, Indiana

I'm looking for info on bike trailers, having checked out some B.O.B. models, the Yakima Big Tow, and Burley's Nomad. Any insights as to which one would be best for city commuting? Also, any suggestions for where I might look for a used one? Linda Olympia, Washington

I currently have an older version of the Tubbs Sierra snowshoes, but I find them to be too bulky and heavy for those trips where crampons are also required. How does the MSR Denali snowshoe compare to its competitors, and what is the "floatability" factor of the MSR snowshoes? It seems they're very narrow, so I'm curious if they will keep you from sinking in soft, deep snow. Scott Newmarket, New Hampshire

Will a pair of electric socks, worn inside waders, work when I'm steelhead fishing? More importantly, will these be safe if I'm wading in water? Ed Pawling, New York

I've got a Bibler Betid tarp, and looking for some extra protection for my Mountain Hardwear sleeping bag (down with Conduit SL shell). I don't want to carry the Betid's floor since it is a bit heavy, and doesn't offer the protection I want. Please suggest a sleeping bag cover or bivy that will allow my bag to breathe, yet shed any moisture from condensation or the occasional exposure to rain. I'd prefer not to break the bank on this, as well. Dennis Staley Englewood, Colorado

What are the alternatives to Gore-Tex? Are there any that stand out from a protection as well as breathability perspective? I would love a Gore-Tex shell, but cannot afford to drop $400 on one. Alex Charlotte, North Carolina

Do you know of any evidence that pepper spray is an effective defense against a mountain lion attack? Mike Rapid City, South Dakota

I have an aging Columbia anorak shell that I'd like to replace. The problem is that I'm having trouble finding any new anorak-style jackets. I don't mind pulling the thing over my head and love the big front pocket. Any suggestions for a replacement, something I can use when hiking, climbing, and skiing? Chris Albuquerque, New Mexico

Where can I buy a hip belt to use as a harness for pulling my homemade gear sled? Bruce Easton, Pennsylvania

Dear gear swi, I'm looking to get back into mountain biking but have absolutely no clue about mountain bikes these days. I haven't ridden one nor done any research in about six years. If you could reach into the vast knowledge that you call a brain and offer some advice on bikes in range of about $1000, I would be in great debt to you. (And I would prefer a hardtail.) J.R. Venice, California

I have a few trips planned in bug-infested territory. The problem is that I hate DEET. I just don't like using the stuff. And citronella-based products are useless. Is there anything new out there that is effective, safe to use, and won't melt plastic? Jake Santos Chicago, Illinois

In November I'll be doing the Hong Kong Trailwalker (www.trailwalker.org.hk), a 100-kilometer race with a lot of big ups and downs. I will probably do in about 25 hours. Last time I did it in Reebok DMX10's. I liked that they were lightweight and I think the cushioning helped my knees a lot on the downhills, but I developed large blisters and lost three toenails, which was rather unpleasant (I didn't get feeling back in one toe for six months.) I'm thinking that maybe the DMX's were just too flimsy for the trail and let my feet move inside them too much. What are your suggestions for other shoes to consider this time around? Mike Luechtefeld Dallas, Texas

After spending all my life camping in the mountains of the eastern United States, I've fallen in love with the southwest Texas desert, and I'm in the process of learning about those techniques and equipment that will work in that very different environment. No trees, blazing sun, the ground too hard to set stakes, fairly constant strong winds... The first problem to solve would be creating some shade... My Integral Designs Siltarp, which works great in the forests of Virginia, is useless as a sunshade, being almost transparent. Are there any tarps out there that would be suitable for sunshade duty, or is a piece of black six-mil poly my best bet? Bill Stell Charlottesville, VA

What is the absolute cheapest sleeping bag that the Gear Guy would recommend for summer backpacking? Some of us have several thousand dollars to spend on our gear—the rest of us are in college. Doug Chicago, Illinois

What's the best and most reliable lighter to take on a camping trip? The top candidates seem to be Colibri and Windmill lighters. Is there much of a difference? John New York City

I looking for information on free-standing tents before heading into the Everglades, where I'll be sleeping in the chickee huts along the waterway. Can you point me to some particular manufacturers or Web sites? Jeff Naples, Florida

I've been reading your archived responses regarding water-resistant sleeping bag shells with great interest as I'm trying to decide between down bags from several of the companies. After your initial (and maybe continued) ambivalence about Dryloft, I was surprised by your negative view of Epic. Especially since many manufacturers seem to have jumped on the Epic bandwagon as having better breathability. On what basis do you believe that Epic is "a condensation trap" in sleeping bags, and why do you think so many are suddenly using it if indeed it doesn't breathe well? Is it just a fad, too early to tell, or should I stick with Dryloft? I look forward to your reply, if you care to go another round on this topic. No Name Given

As a bowman on a racing sailboat crew, I called upon to climb various things. The usual practice is to wear a climbing harness rather than use a bosun's chair as it saves time on the racecourse. My problem is that salt water is corrosive, and our usual sailing area off the south coast of the U.K. is particularly so. I'm not too comfortable going up the mast wearing a harness where the buckles are showing signs of corrosion. Is there a harness with buckles made of stainless steel? Or what other solution could you suggest? Edward London, England

I have been told that Sierra Designs & MSR's new range of four-season tents (in particular SD's Tiros AST and Stretch Dome AST) have floors that are not suitably waterproof for Australia's wet and windy winters. Is this true? Can a waterproofing agent be applied? Also, do MSR's continuous pole sleeves allow adequate ventilation between canopy and fly? What's the verdict on these tents? Justin Trevorrow Darwin, Australia

I'm a road and occasional trail runner. Given the current season, I'm looking for a pair of shoes with a waterproof component to keep my dogs dry when I'm "on the run." However, everything I've looked at so far seems to lean toward trail running in design. This is fine since I'll be traversing ice, snow, slush, and road crud, but the treads on these shoes seem too aggressive for the road. Any suggestions for a good compromise? Ben Marlborough, Massachusetts

I looking for a new lightweight backpack. I never carry over 30 pounds and had decided on the Gregory Reality until I found a new Mountainsmith backpack called the Mountain Guide at a local store. The salesperson told me it was brand new and can't find any information about it. She weighed it for me as the specs didn't include a weight and it ce out about two pounds lighter then the Reality. Does two pounds makes a huge difference in a pack? Kjaristy Salt Lake City, Utah

I recently purchased quite an expensive digital camera. As I'll be backpacking in Montana's Crazy Mountains this June, I'm wondering if it's practical to bring the camera along. If so, what type of bag or protection should I purchase, and where is the safest, yet most accessible spot in my pack to store the camera? Kristin Eden Prairie, Minnesota

If I want to go mountaineering up here in the Northwest, is it enough to slap some crampons onto a pair of Scarpa Rios? I know Rios are great for just about everything else and that they stopped making the Edwardo climbing boot (why, I don't know). Or, should I try some other boot? Jim Trueworthy Coeur d'Alene, North Idaho

Backpacks are a bit of a problem for me because I rather well endowed and the straps get pushed out onto my arms when walking—with all the consequent chafing. Can you recommend a pack with front crossover straps, or an alternative that leaves me unchafed? Deborian Boca Raton, Florida

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

Could you recommend some shoes for water-based activities like kayaking, rafting, and even canyoneering? Water socks are great inside a whitewater kayak, but they don't lend enough support for side hikes and portages. Mike Tempe, Arizona

I'm going overseas for approximately two years. Unfortunately, there'll be no camping opportunities the whole time. Before finding out I was off, I purchased a new tent, sleeping bag, and backpack. What's the best way to store this gear so it's as good as new when I get back? Gil Beaumont, Texas

What do you know about the "Stealth Can" and its effectiveness? From what I read, it's impenetrable to bears and seals in odors to throw animals off the scent. I like the idea of pre-empting animals from entering cp, rather than "teasing" them with food they can smell but not reach. Mark Ewing, New Jersey

Will boiling or adding chlorine dioxide to water neutralize all organic chemicals (i.e., industrial waste)? Also, should you filter water after using iodine or chlorine dioxide to purify it? Does ViralStop (from SweetWater) kill anything other than viruses? Basically, what's the simplest, lightest way of neutralizing EVERYTHING? Seyil Toronto, Ontario

My sweetie and I are going to Everest's Khumbu Icefall this December, where it's likely to be numbingly cold. I'd like to buy her a toasty parka for this trip and have homed in on Feathered Friends' Icefall and MEC's Frobisher. But will those jackets be significantly warmer than our current 550-fill REI parkas? Should I pay for the 800-fill down or Nextec Epic (apparently the best thing since somebody figured out how to shear a sheep) if I go with Feathered Friends? Or should I be looking at other parkas? Robert Fairview, Oregon

I've noticed a strange paradox in my personality. When I go out to the woods, sitting in some remote beautiful locale I often in want of one thing: a margarita. I've often theorized different devices that I could construct to make a blender but nothing ever made sense. And then I found the GSI hand-cranking Vortex Blender. While I would never take this backpacking (OK, maybe on a day trip to be fancy in front of my exhausted friends) I would definitely be interested in it for kayak camping and car camping—so long as the ice lasts. But does the thing actually work? Or is this really a doomed fantasy of mine? I'm skeptical about the amount of effort this thing would take to crunch up ice. I'd love to pop this out and be a hero. Brian McCarthy Glendale, California

Long time reader, first time questioner: I have long been a fan of liquid-fuel stoves, but recently read your advice about the difficulty in obtaining white gas products abroad ["Do they sell white gas for stoves in Europe?"]. I about to head out on a nine-month round-the-world trip, so would like to take along a reliable canister stove. Do you have any information on which canister stoves will mate with the multitude of international propane canisters that I'm likely to find? Europe and Oceania are my probable destinations. Aaron Green Bay, Wisconsin

I'm interested in testing the triathlon "waters." Can you suggest any good bikes for a beginner triathlon biker, say, for under $1,000? Gary Quito, Ecuador

Do you have any tips for taking a dog on trail? I'm taking my dog on her first trip and want to protect my gear without constantly worrying about it. Are those packs dogs wear a good idea? Will she dage the inside of my tent? Kieran Hosey Frankfort, Kentucky

I'm looking for a pair of Gore-Tex mountaineering pants that I can use snowboarding in the Alps, climbing in rainy Scotland, or cross-country skiing in Norway—all without maxing out my credit card. Any suggestions? Jakob London, United Kingdom

I recently unpacked my tent to be hit by a powerful smell of chemicals and mold, so bad that it gives me headaches and I can't sleep in the tent. Could I just wash it with some mild soap to get rid of the stink? I believe that the ses were sprayed with some sort of leakproof sealant, so I think that's why it smells. Janie Kuala Lumpur, Malaysia
