I'm discovering that my late-fortyish feet are inexorably growing longer and wider, and the hiking boots that served me well two years ago are now giving me blisters and scrunched toenails. Companions on a recent Sierra backcountry hike were wearing low-cut trail shoes that looked only slightly more rugged than running shoes, and which allowed their wearers to pretty much dance over the rocks and scree without twisting ankles. For hiking relatively rugged trails without a backpack, what sort of characteristics should one look for in such shoes? And, while I'm here, can one backpack in 'em? Richard Truckee, California

Enlighten me, as I confused. We are planning a 12-month trip and I still looking for the "ideal" water filter. And I in doubt. Which to buy, the MSR Miniworks or the Katadyn Pocket Filter? Aside from the obvious differences (price, weight, flow rate, capacity), the carbon-core element of the MSR is the main difference. But why would I need a carbon-core element? Hans Janssen

It is better to have a full-suspension mountain bike or will a hard-tail with a suspension seat post be sufficient enough for a smoother ride? Paul G. Fort Wayne, Indiana

I'm completely new to backpacking and worried about buying gear from just anywhere. Here in Canada, MEC (Mountain Equipment Co-op) supposedly carries nothing short of the best quality equipment and the thought of going to just one place for all your needs sound really nice. Would you, with all your experience, trust MEC for all your needs as much as everyone here seems to? Or do I have to shop around for everything separately, looking for reviews and such, and then spend tons of money in U.S. stores due to the crappy exchange rate? Your answer is greatly appreciated. Tatiana Calgary, Alberta

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

A friend and I are planning an attempt to summit Mount Shasta this summer. Neither of us owns an ice ax or crampons and we plan to rent those items when we get to the area. But recently I've been looking at Kahtoolas, which are kind of "crampons light." They're aluminum with no front points and touted as compatible with everything from hiking boots to running shoes. Looks like they might be adequate for a trek up Mount Shasta. Also, I might get some use out of these in future winter hikes. But they are north of 100 bucks (in the same territory as some entry-level crampons). Do you have any experience/insights on Kahtoolas? Mitch Thompson Shaker Heights, Ohio

As the years go by, my wife and I find ourselves looking for lighter and lighter hiking and camping equipment, especially in terms of our shelter which takes up a significant portion of our pack weight. What's the word on Henry Shires' Tarptents? Their Squall weighs only 24.5 ounces and offers two people a roomy 44 square feet of space. Could this be the lightweight remedy to aching backs and our three-season shelter needs? V. Tran Galveston, Texas

Raichle's Mountain Trekker backpacking boot is the best boot I have ever owned, and I would like to purchase another pair. However, I can't find anyone that carries them anymore. Could you help me out with information on where I could get a pair? Trevor Calgary, Alberta

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 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

Are there any leather boots that will hold up on the "big peaks" like Denali or Everest? I planning a trip to Denali and would really like to go with leather boots as I've never liked plastics. Any thoughts? Jeff Norfolk, Virginia

Where can I buy climbing/hiking knickers? I used to wear them in the '70s, but styles have unfortunately changed. Now I don't know of a single outfitter that carries them. Anything from European sources, perhaps? David West Monroe, New York

I just recently returned from a failed Mount Rainier attempt feeling deflated because my Koflach boots chewed up my feet before we even got to Cp Muir! I've been reading about the Asolo AFS Guide boots and they sound great. Where can I purchase these and will they work with a smaller, narrower woman's foot? (Living in North Carolina, I will have to play mail order.) I also tried some Lowas to no avail. I'm going back for another Rainier attempt next summer and would hate to fork out another $800 and not even make it to base cp. Karla Greensboro, 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

For multi-day trips to the Sierras, I've been using an REI Wonderland external-fre pack, 5,000 cubic inches of cavernous, organized, old-school pack. Everybody I see these days, though, has internal-fre packs that look so comfortable (maybe they're fooling me). I still living in the '80s with my Wonderland? Is it time for an internal-fre pack? If so, any suggestions? Alex Chino Hills, California

I'm fortunate enough to live a half-hour from Shenandoah National Park. Often I'll drive out there after work, park by the side of the road somewhere, walk into the woods, and sleep there for the night. My little travel alarm wakes me in the morning in time to get to work. If the weather is dry, I sleep under the stars, but I like to carry a light tent or tarp for sudden showers. So I looking for a one- or two-person tent that is: 1) Quick and easy to set up; 2) Weather-tight enough to keep me dry in a thunderstorm; 3) Moderately light; and 4) Fairly roomy. Any suggestions? Would a single-wall tent be a good choice? I've looked at the Integral Designs Siltarp too—would that accomplish my purposes? Bill Stell Charlottesville, Virginia

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

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

Sage of swag, I'm in the market for a road bike, and looking for direction. Initially, I'll be using it for fitness riding, but I anticipate riding in local road races in the future. I'm a family man with a limited budget for recreational toys. That said, I want something that's going to stand up—a bike that I won't have to replace or extensively or upgrade as I get into the sport in a bigger way. Is a bike equipped with Shimano 105 group the "minimum" I should be looking at? Which models should I be considering, and at what price point? Greg Basky Saskatoon, Saskatchewan, Canada

I wear prescription lenses in my sunglasses and want to get a similar custom-made pair of glasses for paddling at night. I've heard that a yellow tint on the lenses helps to bring out objects. Is this true? Is there anything else I should consider when ordering this pair of glasses? Dennis Milton, Florida

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

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

What are the pros and cons of jackets made with Ventile? Is this material worth the money? What about Nextec? Alex Strongsville, Ohio

What's the best two-person tent for under $300? Tom Ireland

What's the best two-person tent for under $300? Tom Ireland

Recently a couple friends and I attempted a 14-mile backpacking trip alongside a Class II-III river, with 90 percent of our time spent boulder-hopping, the remaining 10 percent waterborne. Unfortunately, we only managed to go three miles before the small recreational rafts we had to transport our packs got ripped up by the rocks and all the bushwhacking. In light of this, do you know of any companies who sell floating backpacks? Or is there some kind of easy-to-pack inflatable for transporting gear through water. We'd like to complete the se trek next year, but need a better way to float our backpacks. Travis Roseville, California

Is there a watch out there that is a dive watch and also an altimeter watch for skydiving? Ryan St. Petersburg, Florida

My 2003 hiking season shall henceforth be known as the "Summer of the Bee," for all the stings I got. The long spell of dry weather was suggested to me as a reason, which I liked better than bad karma! Anyway, I quickly used up the three sting wipes in my first-aid kit and now own both REI's Sting Eze and After Bite. To my surprise, these two products use completely different active ingredients. Which one works best on stings? Chris Silverdale, Washington

What tools do I need, and how do I build a good snow cave for winter camping in the Colorado Rockies? Daniel Denver, Colorado

I read the article about the Crawford Survival Staff in the 2000 Buyer's Guide, but I wanted to ask if it's really worth the $225. You're the only source of reliable information I have! Did you actually field-test the staff? Alex

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

What are the best boots for snowshoeing? I've tried winter boots and cross-country ski boots, but none of these fit well enough in my snowshoes. Jean San Francisco, California

What sort of cookware will I need on two- to four-night backpacking trips in the Appalachian backcountry? Kenny Birmingh, Alabama

What sort of cookware will I need on two- to four-night backpacking trips in the Appalachian backcountry? Kenny Birmingham, Alabama

"I just got through watching reruns of the Eco-Challenge, and was wondering what those competitors (and us less adventurous hikers) can do for very wet, muddy, and slushy hiking conditions? How about Gore-Tex socks and some strips of duct tape around each calf to keep the water out?"

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

I looking for a boot that can do just about everything, including hiking, backpacking, mountaineering, as well as a little bit of climbing and bouldering. I would also prefer a crampon-compatible boot that can handle the snow and cold. Any suggestions, besides going out and buying five different pairs of boots? Jeff Midland, Michigan

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'm planning a through-hike of the Continental Divide Trail this summer, and I want to go ultra-light. What's the best tarp to use—the easiest to set up, the best in wind, and so on? Syd Seattle, Washington

I'm going to Alaska's Denali in June, so are there any particular jackets out there that you would recommend? Would the Marmot Parbat Parka be sufficient on a breezy day atop Mount Denali? Eric Maryland

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

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

What are the best winter socks for snow skiing? When I ski, I rent boots and skis, but I find my feet always get cold. What socks should I get to make sure my feet stay warm? Should I use sock liners in addition to high quality wool socks? Brad Chapel Hill, North Carolina

I'm in the market for a new sleeping bag and would like to give a down bag a try, mostly because of space and weight issues. I'd be using it primarily as my summer bag, so a 30-degree rating should be enough. Do you have any advice for a good down bag? Andy La Crosse, Wisconsin

Have you heard about the latest craze in the U.K.? It's called Paro clothing, and the claim is that you'll be throwing away all of your Gore-Tex outerwear when you start using it. What gives? A friend of mine who is a guide in Scotland lives by the stuff. Do you have any thoughts on the stuff? Is it all that it says it is? Arthur Long Valley, New Jersey

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

Your Gearness, what boot do you think I would need for a four-month trek across the Indian Himalaya? I have a pair of Montrail Torre GTXs, but will these suffice? Tony Baltimore, Maryland

I recently purchased an Annapurna tent from Mountain Hardwear, because I'd like to start getting outdoors on more than day trips. However, the guy at the shop was reluctant to sell it to me, saying it was "junk" because it's a single-wall tent. What's the difference, and what are the advantages and disadvantages of this style tent? Lucas Denver, Colorado

I enjoy weekend hiking and overseas travel. At the se time, I want to look good when I dress casually. Because of this, I spent $400 on a Patagonia XCR Gore-Tex jacket when Patagonia opened its first branch in Hong Kong last year. It's a very expensive outfit, but I do like it. However, after reading all your gear recommendations, it seems I could have bought something similar or even better. So, I'm now thinking of buying a fleece jacket for cold weather. Do you have any cheaper recommendations? June Hong Kong

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

I've finally decided to buy a GPS unit. My problem? I don't know which one. Your last review that I can find is three years old, but obviously a lot has changed since then. Rick Lebanon, Tennessee

I'm planning a 14-day backpacking trip down Utah's Escalante River next month, and puzzled about the ideal footwear to pack. The route involves lots of wading, often over rough riverbeds, as well as slickrock hiking, all while lugging a big pack. Is there a boot out there that can provide good drainage as well as some serious support? David Grinnell, Iowa

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

Dr Gear Guy, please realize that you are completely indemnified from any liability as to the efficacy of your answer, but I'm wondering what gear you'd specifically recommend for a hiker who has undergone a total hip replacement and refuses to cast a deaf ear to the call of the wild? I have a pair of good trekking poles. Anything else come to mind? Keith Columbus, Ohio

I going kayaking in two week's time to Big Bend. As I've never done it before, I'd like to know what gear is needed so that I don't freeze in the water. Luis San Antonio, Texas

Long time read, first time question. I'm a skinny guy. I love to ski, mostly at resorts but a little OB. My question, then: Is there a jacket-shell combo, or maybe just a jacket, that would keep me warm when it's zero degrees and windy, breathe when it's not that cold, and not make me feel like the Marshmallow Man? Timothy Rockaway, New Jersey

Are you sure about your advice (February 5, 2003) that it's OK to use the Coleman BlackCat heater in a tent? Coleman's Web site shows that one of their BlackCat models has electronic "ignition," so that no matches are required. It also says that it's safe to use them indoors "with proper ventilation." Maybe it would be worth calling someone at Coleman and asking their opinion. Michael Vancouver, British Columbia

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 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

Great burning bush of the gear desert, Marmot Precip hat or urban sombrero? I want to buy a good waterproof hat; hoods are cool and all, but they're sometimes a pain in the fanny pack. I have read that you often prefer hats to hoods. So, would you choose the Marmot Precip Safari Hat, the Outdoor Research Seattle Sombrero, or something different altogether? Please help me before I do something dumb—like ask someone else. Jay Eugene, Oregon

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

How do you know when it's time to replace your running shoes? I have been road running on a pair of New Balance 804s for about a year. I weigh 200 pounds and run about two to three miles five days a week. Any suggestions for new shoes? Craig Portland, Oregon

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

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

My wife and I will travel overland from Vietn to Turkey in 2003. We cannot decide what sleeping bags to take, as it will be very hot and wet in Vietn during the monsoon season, but cooler and dry when we are in Central Asia. Space, weight, and price are all issues. What do you think? Is there a light, extremely compact bag that will work when hiking in the jungle and also keep us warm in colder, alpine conditions? For the record, the tent we plan to use is a 1.3-pound mosquito net, with a fly and pegs if things get a bit windier. Andrew Darwin, Australia

Boy would I like your job! Anyway, next year I plan on doing some multi-day trail runs, so wanted some pack recommendations. These will most likely be overnight excursions, and there'll be two of us, so we can distribute tent components. So, what pack would you recommend to carry all my gear (half the tent, lightweight sleeping bag, some light wet-weather gear, food, water, sundries)? I was looking at packs around the 26-litre mark, but wondering if that'd be enough. Rob London, United Kingdom

I interested in purchasing a multi-functioning watch, such as the Suunto Vector, something with an altimeter, barometer, and the like. I'd be using it when hiking, camping, or mountaineering; I'd even like to swim with it on. Is Suunto the only company that makes these watches? Is there a hiking watch that can do it all, even when it's freezing and underwater? Tony Detroit, Michigan

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

Most high-end down sleeping bag manufacturers state that THEIR shell material is the best for both breathability and water and wind resistance. After reading the specs on all the different shell-fabric brands, I'm left feeling dizzy. A friend says that Gore DryLoft is best, but then other reputable companies say Conduit, Hyvent, G3, Pertex, or Epic is better. Help! Which one would you choose? David Sparta, Michigan

Can I use a standard tarp as a footprint instead of the manufacturer's footprint? Are there any significant differences between the two options? Ne Withheld Bangkok, Thailand

Man, I confused! I want to purchase a synthetic-fill jacket for an upcoming canoe trip in Big Bend National Park. But it seems that all the major brands employ a different type of fill, running the gut from Polarguard HV and 3-D to Heatshield and Primaloft. So, Doug, I turn to you for expert guidance. Which is the best synthetic fill for warmth and compressibility? If there is not a "best", then what are the advantages of each? Finally, what jacket would you take? Steve Hurst, Texas

Do you know where I can buy one of those Mountain Hardwear sleds? Who else makes sleds for hauling gear? Thom Salt Lake City, Utah

Luckily, my company is relocating to a place where I'll be able to ride to work! What will I need to commute by bike three or four times weekly? I already have road and mountain bikes, plus the gear, but I don't think my racing garb will work for the daily commute. Loehr Athens, Georgia

How do I get Christmas-tree pitch out of a Gore-Tex jacket? Karen Gresh, Oregon

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

Would you recommend a waterproof poncho for backpacking? My friends and I are thinking of doing the West Coast Trail on Vancouver Island this summer. I have heard that even the best Gore-Tex fails under the onslaught of seven days of heavy rain. Previous trail users have suggested carrying a waterproof poncho to cover you and your pack. What are your thoughts on this idea? Chris Barnes Silverdale, Washington

Is Gortex XCR a form of Activent that has been taped and se-sealed? Activent is a great product, totally windproof and highly water resistant, but wouldn't this have been waterproof too if it had been se-sealed? Herb Morganville, New Jersey

In the piece on Sno-Seal you said, "I'm confident it's the only product to appear in both the 1943 and the 2003 REI catalogs." I wonder if that's true. I think it would be really cool to see a listing of the items that were in the first REI catalog that are still in the current one, and the price differences. Don Denver, Colorado

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

I'm curious to hear your opinion about Osprey's line of Ariel backpacks, particularly their Ariel 75. I can't seem to find any reviews on anything other than the Aether 60. I loved the Osprey Luna 75, but I'm looking for something slightly lighter. My main concern is whether the suspension of this smaller pack will hold up under a 40-pound load. I don't want to sacrifice good load transfer and stability simply for the sake of a lighter pack. Erica Boston, Massachusetts
