I recently started taking my dog with me while backpacking, and he loves it. But, should I worry about him drinking from lakes or stres? Should I filter his water for him? Kevin Mississauga, Ontario

I have been looking at jackets and vests from GoLite, and they all seem pretty cool. Logic tells me that their stuff probably doesn't keep one as warm as the heavier stuff other companies offer. Can you confirm that? Matthew Sattah Chattanooga, Tennessee

Do you know of any fully waterproof/breathable gloves made of two- or three-ply Gore-Tex? I'm looking for a glove that I can use for mountain biking when it is 40 to 50 degrees outside and raining hard. I'm not looking for a full-blown expedition climbing-type glove because I won't be out when it's 0 degrees. I've seen the Seal Skinz waterproof gloves but the outside material will retain water pretty much like a sponge. Steven Fleisig Upper Montclair, New Jersey

I've heard that deet will destroy nylon and nylon-blend materials such as tents and quick-drying garments. Is there an effective insect spray that can be used on these materials? Mike Tpa, Florida

There is a well known canoe camping writer that advocates using a plastic ground cloth on the INSIDE of your tent. He says that not only will you be drier in a downpour, but that it will protect the tent floor just as well as if it is placed underneath the tent. What are your thoughts on this subject? Dave Cbridge, Minnesota

I'm really getting into ultralight backpacking, and I hope to do a through-hike of the AT or PCT in the next few years. I do all of my backpacking in the summer, but my Marmot sleeping bag is too heavy (and warm). What choices are there for a light, compressible bag costing less than $100? If there are no bags in this range, would you recommend removing some of the down from my Marmot bag to make it lighter? Tom Bellevue, Washington

Why don't sleeping bag manufacturers make the outer shells on their bags from the se materials used in waterproof-breathable jackets? Thanks for your time and answer. Steve Youngsville, Louisiana

My wife and I like to share a cozy sleeping bag while kayak camping, but we both own "pre-marriage" bags that don't zip together. What we want is one bag wide enough for two, made from synthetic material (since it might get wet), and with a temperature rating of about 20 degrees. Also, as we're both about five-foot-five, it would need to be on the short side. Is our only choice to have a bag custom-made? Andy Kirkland, 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 often ski and snowshoe in the Adirondacks backcountry, but my back always gets soaked under my pack whenever I'm going uphill. I have tried different layers to avoid the wetness, all to no avail. What do you recommend to keep my back comfortable? Ian Lake Placid, New York

Despite the current trend towards light-and-fast hiking/backpacking gear, no manufacturer besides Eureka has looked at the rolled up size of even ultralight tents. They're still 5 feet by 18 feet or longer. Why not 6 feet by 12 feet? Or 6 feet by 10 feet? I've seen tents I'd really like to purchase but their packed size is too long to fit a small pack. Why is this? Ken Johnson Hollister, California

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 have a five-and-a-half-year-old son who likes to hike with dad. Our problem is that we can't find good hiking boots for him. He has a pair of fine Salomon boots we purchased from Cor two years ago, but he has since outgrown them. His feet are a wide size two, which complicates our quest to outfit his feet. Bob Penfield, New York

I've heard that under non-extreme conditions my hiking pole can be used as a self-arrest tool when crossing steeply inclined snowfields. As much as I would love to buy an ice axe and add it to the chaos of my gear closet, I don't want to purchase an item when an existing tool would work just as well. Should I indulge my gear habit or stick with what I've got? PG Hancock Littleton, Colorado

Yes, as an overpronate runner weighing in at 210 pounds, I probably should take up a less impact-prone sport. But I'm still running, so I need some shoes with torsional stability and impact-absorbing capability. For the past year, I have been running in a pair of Brooks Beasts, which have worked pretty well, but not perfectly (Spenco insoles helped some). Can you recommend several running shoes that are suited for a runner of my build? Charles New York City

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

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

My son is travelling to Costa Rica. He wants to take a small camping stove with him. Do you know what kind of fuel is available in Costa Rica and can you recommend a particular stove? Debbie Walker Vancouver, British Columbia

I interested in buying rappelling gear and I unsure as to what I need. Is there anywhere that I could find a list of must-haves for rappelling? Todd E. Clyde Hurricane, Utah

I looking to buy my first mountain bike and the more I look, the more frustrated I get. I've read some reviews in biking magazines, as well as Outside's March 2003 review of full-suspension bikes. Anyway, I'm looking for a full-suspension model with smart or rear-suspension lockout and good components (disc brakes would be a plus). Here's the kicker though: I looking to spend around $1,000, give or take a few hundred. I don't think that's unreasonable, so do you have any suggestions? Alex Hayward, California

I have been unsuccessfully combing the Internet for a pair of boots that possess a few specific features: full grain leather, a waterproof-breathable membrane (e.g. Gore-Tex), and a gusseted tongue. If you can help me find a pair of such boots for under $150 please tell me where! Lucas Mead, Washington

Help. After a winter of commuting by bike, my helmet stinks. I wear a helmet cover in the cold so sweat tends to accumulate and my head sweats a lot. I have tried washing it with antibacterial soap, but that only helps a little. I afraid of spraying Febreeze or other chemicals on the helmet's interior because I don't know if they would effect the safety of the helmet. And now my wife says that my head is beginning to smell as bad as my helmet. Before I either have to get a new helmet or sleep in the garage, is there anything I can do to get the smell out? Kevin Dalton Calgary, Alberta

I've recently been in some heated discussions with fellow campers over whether it's warmer to sleep naked in a sleeping bag or to wear some loose clothes. Logic would seem to suggest that more layers equal more insulation, but a surprising number of acquaintances swear they're warmer naked. Can you give me a definitive answer?

I'm a woman with very small wrists and have had great difficulty locating an altimeter watch that I can actually wear. Are there any smaller altimeter watches out there designed for women? Tally Rockford, Illinois

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

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

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

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

Is it sometimes desirable to hang your stove, for cooking in your tent? If so, who makes the devices to do this, and is it specific to stove model or is there a generic one? I own a Peak Apex II. Ron Starrett Vernon, Connecticut

Dear Gear Guru, Here is a question that no one ever talks about: the dreaded first aid kit. Of course, you'd never get injured, but in case you did, what do you recommend packing in the way of first aid for weeklong wilderness trips? I have looked around and can't find a pre-packed kit that seems very comprehensive. Andrew L. Salt Lake City, Utah

I'm going to a mountainous part of New Mexico this summer. On a previous six-day trip I took a pair of Asolo 535s, but this time I'll be trekking for about 12 days, in addition to a couple of shorter hikes to get acclimated. Since my old pair will need to be put to pasture (they deserve it), I'm wondering if the Asolo 535 will be tough enough for a longer trek, and also whether a pair of thicker Montrail Vercors boots might get too hot in New Mexico. Dave Charlotte, North Carolina

I was out hiking in the west Texas desert a few months ago during a delicious spate of rainy summer weather. I was wearing a light pair of boots and found myself slipping and sliding all over the wet rocks. Crawling on my hands and knees over boulders is not my idea of fun, and it really ruined my week. I'm now in the market for a pair of light "day hikers," with soles that'll give me some traction on wet rock. Any suggestions? Paul San Antonio, Texas

What do you think of the Yashica T4 Zoom camera? In the past, you often recommended the now-discontinued non-zoom Yashica T4 Super; the T4 Zoom is advertised as its replacement. What is your verdict on the T4 Zoom? Worthy successor to the T4 Super, or an imposter with a trendy zoom lens that has unfairly appropriated the respected T4 moniker? Jock Washington, DC

I'm looking for a pair of waterproof, breathable pants that will keep me dry and also withstand the rigors of off-trail bushwhacking (K-9 search-and-rescue work). The cheaper the better, ideally less than $200. Durability is key and full-side zips would be nice. I'll be using gaiters, so built-in gaiters on the pants aren't necessary. Thanks for your insight, Gear Guru. Eric Portland, Oregon

Do suspension seatposts significantly alter the seatpost height? I currently own a 1997 Cannondale hardtail and I would really like to prevent my spine from someday poking through the top of my helmet. But I'm worried about altering that sweet-spot seat height that has so graciously prevented knee pain thus far during long rides. Preston Fall Vancouver, British Columbia

Please help! I recently bought a new lead climbing rope (Bluewater Accelerator 60m 10.5 mm) and I did what I have always done: mark the middle with a Sharpie marker. Then the other day someone told me this significantly weakens the rope at the marking, enough in fact to cause the rope to break in a relatively mild fall. I wasn't sure about this, because I thought it only marked the sheath and didn't affect the core of the rope. Should I throw the rope out? I would rather not due to the expense, but I will if it's gonna cost me my life! Mike Pittsburgh, Pennsylvania

The principal of "one pound on your feet equals five on your back" seems to be treated as Gospel, but I don't buy it. I moving in the direction of an ultralight pack but loath to give up the fit and support of my heavy Limmer boots. Where do you stand on the matter? Steve Kennewick, Washington

I want to buy new liner socks to use for backpacking. Since my last purchase of these, many more choices of fabric type and combinations have become available. What have you found to be the best buy? Dennis Bender Hilton, New York

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

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

Hailing from sunny California, this is my first year in college in Boston. Here's my situation: New England weather is windy, chilly, and often wet. I need a jacket that will get me through the winter but also look good around town. However, once I buy this jacket, I'll still need money to eat. What can you recommend that won't break the bank, i.e. as close to $100 as possible? Kyle Boston, Massachusetts

Not yet having gone digital, I have a standard 35mm camera with extra lenses, a detachable flash, and the requisite rolls of film and cleaning cloths. So, I'm looking for a backpack-style camera case with plenty separate compartments and padding. Ideally, it'll be sling-style, with small compartments on the front for ease in changing films, lenses, and so forth. I've already checked the local stores and a few large Internet sites, but they seem to make bags only for digital cameras now. Any suggestions? Sarah Tulsa, Oklahoma

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 planning a two-day, one-night hiking trip along the Appalachian Trail and looking for a gear list. Could you suggest what to pack and a couple of menus (with per person measurements)? The last time I took a trip, my girlfriend and I lugged so much food we could have fed five. Seth New York City

My wife has been using a pair of Asolo AFS Ridge boots for our backpacking trips, typically extended ones through rugged terrain. The Asolos blew out a se in front of the laces and need to be replaced. We are considering the Montrail Moraines or the Asolo 520 GTX boots. Is the Moraine too much boot? Is the Asolo 520 enough boot? Any other suggestions? Louis Oregon City, Oregon

I'm hiking the Grand Canyon rim to rim this spring, and I'm wondering what footwear to use. I like the lightness and cushioning of the trail runners that I've been using for my ten-mile training hikes, but I'm wondering if I need something a little more burly for my unsteady legs over the course of the 24-mile hike. Any thoughts on the Lowa Tempest? Jay Phoenix, Arizona

I want to upgrade from a cheap pair of compact binoculars. Assuming I had a pile of money burning its way out of my pocket, would I see much difference between a pair of Nikon Travelites and Leica Trinovids? Also, are there any other models I should look at (through)? Joe Lawrenceville, Georgia

Much of my clothing made with high-performance fabrics, such as Coolmax, states that you should not use fabric softeners or dryer sheets. Why is that? If they are accidentally dried with a dryer sheet will they return to normal after the next wash or are the performance aspects ruined? Joe Helm Canal Winchester, Ohio

I have a narrow foot (11B), and find most hiking boots are D-width or wider. Any suggestions for boots that come in narrow widths? John W. Stafurik Los Alos, New Mexico

I recently heard about a new water bottle for hikers that doesn't slosh. I can't remember who advertised it. It was a bottle with a baffle type device inside it. I called everywhere, and searched the Internet, but couldn't find it. Can you help? Dean Willis Boise, Idaho

Thanks to a little bicycling accident last fall—which resulted in four brain surgeries—I've decided to take up hiking. I'm considering a staff or trekking poles to help with my balance. I believe trekking poles would be overkill for me, and that a single staff would be fine, particularly since I'll be sticking pretty closely to trails. Do you agree, and if so, which staffs would you recommend? Roley Davidson, North Carolina

G'day Gear Guy, I off to Peru in June for some high altitude climbing and I love all my toes. I currently have Salomon Mountain Guide 8's leather boots. I not a fan of plastics and looking to see how I can upgrade the warmth of my Salomons. What would be your recommendation for gaiters/overboots? Would this be enough? Cheers, Greg Brisbane, Queensland, Australia

We have a cabin tent that leaks, mostly from the bottom corners and stake-out loops. I have sprayed the tent and sealed the ses, but it still leaks. Is there anything else I can do besides trash this store-brand tent? As for new tents, the Eureka Getaway 9 or Coleman Sasquatch both fit size-wise; I don't want to spend over $250, though. Lastly, why do air mattresses always deflate while you're sleeping? Do they have a low life expectancy? Sarah Granite City, Illinois

After a long hiatus (scared off by all the stories of cycling-induced impotence), I getting back into road biking. I own, and love, the all-purpose Leatherman Wave multi-tool, so would like to get a similar device for my bike; which, if any, do you recommend? Your acolyte in Albany. Steve Albany, New York

I have one of the new MSR MiniWorks EX water filters, my first, and it works great. One of my buddies tells me to filter water from a still pool, but another says to filter from fast-moving water: Do you think it matters much? Personally, I just try and go for the clearest water I can find. Mike Eldorado, Illinois

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

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

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

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 considering purchasing a jacket and pants made of Gore-Tex Paclite that are on sale. Some of the garments I'm considering (Devil's Thumb Jacket and a Dabl Pants from The North Face) are no longer made with Paclite but are now made with Gore-Tex XCR. The jacket and pants are selling right now approximately 50 percent off, so they are a relatively good deal. Should I be wary of Paclite since TNF has stopped using it? Thanks for your advice. Jay Lenrow Baltimore, Maryland

After a few cold nights at high elevation I interested in investing in a 0-degree bag. My research has directed me towards a down bag, possibly with a Pertex or DryLoft shell. I have been considering the Feathered Friends Tern, but know little about the company. I've also looked into the Mountain Hardware Universe SL, but don't know the effectiveness of the shell. I would greatly appreciate your input. Carissa Colorado Springs, Colorado

Even with the netting on, my tent (The North Face's Roadrunner 2) gets really hot in the summer with the flysheet on. Could I just hang a tarpaulin above the tent and leave the fly at home? Wouldn't that provide good sun and rain protection, while also allowing for much greater ventilation? Grah Winnipeg, Manitoba

One quick question—how do I pick the right length for an ice axe? Thanks, you're the man! Paul Anacortes, Washington

What do you think of the Yashica T4 Zoom camera? In the past, you often recommended the now-discontinued non-zoom Yashica T4 Super; the T4 Zoom is advertised as its replacement. What is your verdict on the T4 Zoom? Worthy successor to the T4 Super, or an imposter with a trendy zoom lens that has unfairly appropriated the respected T4 moniker? Jock Washington, DC

What's a good bike light to buy for my boyfriend so that he can mountain bike at night? Something inexpensive but good quality, which will probably get used once or twice a week in good weather. Julie Boulder, Colorado

What's your opinion of the Trailstove wood burning stove for backpacking? Bill Stell Charlottesville, Virginia

Please help! I recently bought a new lead climbing rope (Bluewater Accelerator 60m 10.5 mm) and I did what I have always done: mark the middle with a Sharpie marker.

Everything I read about tents says not to cook in the vestibule, but then I read gear reviews that say it is large enough to cook in. What's the scoop-is it safe to cook inside your vestibule or not? Shaun Aleda, California

Hello Mr. Gear, I'm going to the Arctic National Wildlife Refuge late August/early September this year. Since the place is beyond the Arctic Circle and the timing is going to be late, I wonder if my insulating jacket—a Wild Things primaloft sweater—is going to be warm enough. Also, what's the difference between a three- and a four-season tent? We're trying to decide on a tent to take along, but I wonder if I should take a four-season tent. Last year we took a Sierra Designs Meteor Light to Alaska, but it really didn't perform under the gusty conditions. And this year, we're expecting very very windy conditions as well. Is there any three-season tents that can live up to gale force winds, or I'm just stuck w/ the dead weight of a four-season tent? Blanche Ingr Brisbane, Australia

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

I'm planning a summit attempt on Mount Rainier this August and a possible bid for Denali in May 2004, so in the process of upgrading my gear, particularly boots and sleeping bag. My budget may not allow for separate gear for each climb. I've been looking at Millet's Everest Boot and the North Face Inferno bag as my options, but prices are steep! Do you have any other suggestions, and is this gear suitable, or even overkill, for both climbs? Michael Stoneh, 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 for an internal fre pack that will handle solo weekends, and group week-long outings, but most importantly, comfortably fit my petite (105-pound), feminine fre without breaking the bank. What do you suggest? y Walsh Tallahassee, Florida

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

I'm looking for a recommendation for hydration packs as Christmas gifts for my brother and his girlfriend. They live in the Bay Area and do a lot of outdoor activities such as trail biking, hiking, and climbing. Would you recommend the se model for each of them, or different ones? Verna Washington, DC
