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 looking to buy a new tent for canoe tripping in the barrens of Canada's Northwest Territories. I expect lots of wind and rain so an expedition tent would be best. But what is an "expedition tent" anyway? Robert Guelph, Ontario

In answering the question, "What's the lightest three-person tent available?" a few weeks ago, you missed by far the lightest candidate: the Stephenson WarmLite! It can weigh as little as 3.25 pounds and has 52 square feet of space! Dave SteinerNew York

What type of bag would you recommend for climbing Denali? Down or Polarguard insulation? What specific bag would you recommend? What about as far as clothing—layers, brands, models etc.? Would you recommend a full down suit? Or a down jacket and either down pants or a shell with layers? Bob Grish Boise, Idaho

I planning a weeklong sea kayaking trip in northern Quebec. I (and my backside) would appreciate any of your thoughts on a decent portable sleeping pad. Is inflatable the way to go? And what about length? We anxiously await your deliberation. Nicholas B. Westmount, Quebec

I have been happily skiing and snowboarding in my Patagonia Nitro II pants for the past few years. However, having recently signed up for a mountaineering course, I was told they aren't designed for mountaineering because of their two-ply, mesh-lined material. I'm confused as to why pants perfectly fine in a skiing environment can't work for mountaineering. I don't want to shell out $300 on another pair of pants! Ken Toronto, Ontario

Can three-season tents be used in the snow? Is it necessary to have a "mountain" tent for snow camping? With a full cover fly, what is wrong with using a three-season tent for occasional snow camping? Lyn Greenhill Roseville, California

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

I have a bit of a problem. I must have put my pack away a little wet after a spring backcountry ski trip and now all the waterproof coating is coming off the inside of the pack. I have a siliconized nylon pack cover that I will probably use for an upcoming Sierra trip and sprayed the outside of the pack with Nikwax. I also always use a garbage bag inside of the pack to protect my gear. Do you think the pack is done and I need to bite the bullet and buy another? Or do you have any suggestions of ways to fix it? Tim Newport Beach, California

I'm looking to get a lightweight and compact pair of binoculars to carry with me on hikes. Do you have any general tips and some recommendations for good buys? Joe Voelcker Philadelphia, Pennsylvania

With all the high-tech lenses out there, I'm looking for a pair or two that will provide good protection in a variety of situations. I would be using them for downhill skiing, water sports, motorcycle riding, driving, hiking, mountain biking, roller blading, etc. The three brands I considering are Revo, Oakley, and Serengeti. I was also told by someone a long time ago, that it is not a good idea to wear polarized lenses when riding a motorcycle, as they will hide oil spots on the road, causing a potential slide. Can you tell me if there is any truth to that? Tom Player Toronto, Ontario

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

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

This July I climbing Mount Rainer. My climbing partners have told me that a synthetic bag is necessary because of the rain. They recommended a 25- to 40-degree bag. We are going light and fast, and plan on using open-air bivys, so I think a bag with a microfiber shell would be a good thing. Unfortunately, I not having any luck in my search for the perfect bag. I have stumbled on only a few bags that are synthetic and have microfiber shells. Integral designs makes one, but it uses Primaloft2 as its insulation material. I have been warned to stay away from short-staple fibers because the bags don't last very long. Do you have any suggestions? Mike Ads Newark, Ohio

My wife and I are going bike camping this summer. Are there any light two-person sleeping bags, or single bags that zip together? We need the bag(s)—preferably down filled—to also fold down as small as possible. The cheapest we've found is about $500 for two. Do you have any better suggestions? Harvey Davis, California

My family and I enjoy car camping in Alaska's interior. However, as I get older, I'm finding that my back gets stiffer using my old sleeping pad and that my air mattress doesn't give enough insulation. What type of pad or combination of pad and air mattress do you recommend to minimize back pains, provide insulation, and allow for a comfortable night's sleep? Shane Juneau, Alaska

Is DryLoft on a down sleeping bag worth it? I've noticed that it's not appearing as often as it used to on down winter sleeping bags. David Morlock St. Paul, Minnesota

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

What is the best type of footwear to wear when snowshoeing? Do I wear my hiking boots (kind of stiff but durable)? Or my low-cut trail hikers (comfortable but less durable)? Or something else? Katie Gold Boston, Massachusetts

What's the best backpack for scrambling? I have taken to canyoneering, usually carrying trekking poles for balance, two ropes, other climbing gear, and occasionally a wetsuit. I'd like to know if there's a slim, lightweight, 3,000- to 3,500-cubic-inch pack that will hold the poles, a water bladder, and my climbing equipment without making it look like I'm tackling Everest. Ray Chicago, Illinois

"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?"

What type of shoes should I wear for day hiking in the Costa Rican rainforest—sandals, trail runners, or water shoes? I will be going in November, historically one of the wettest months of the year. Dion San Francisco, California

Do water bladders sweat inside a daypack? My daypack is big enough to hold a bladder, but I'm worried my other stuff will get soggy if I pack next to a bladder. I worrying for nothing? No Name Given

I read a column you wrote last February on weatherproof digital cameras. Is there anything new that would fit the bombproof, sand-proof, waterproof category? We work as river guides so the cameras get some hard use. I also looking for a camera for my 11-year-old daughter, traditional or digital. Any recommendations? Peter Coeur d'Alene, Idaho

On extended backpacking trips, does it make sense to pack both a soft shell and a waterproof jacket? Or just take along the rain jacket? Also, since I come from Europe, I'm a little bit confused about what exactly cross-country skiing is. I know what telemarking is (those graceful people on the piste) and also langlauf (with the thin skis), but what is cross-country? Karl Cottenie Leuven, Belgium

Last summer, I bought a Shan light touring kayak from Wilderness Systems (based largely on your recommendation, O Great and Wise One). After some great day trips, I'm now planning a multi-night river trip, so I'm looking for some packing advice. The boat has a rear bulkhead and an air bag up front for flotation. Should I pack my gear at the back with extra stuff lashed atop the stern, or can I replace the front flotation bag with a tapered dry bag? Zippo Baltimore, Maryland

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

What's your take on Backpacker's Pantry Outback Oven? Does the Outback Oven really bake well and also conserves fuel for cooking traditional grub? After a zillion meals of mac and cheese, ren, gorp, and dried fruits, the Ziplocs carrying the food start looking more appetizing then the food within. The idea of dining on hot cinnon rolls, fresh pita bread, pot pies, or (gasp!) brownies does make me wonder if the Outback Oven really works or if it's just another ravenous hikers delusions? Ed Beaudry Laurel, Maryland

Years ago you recommended The North Face Snowshoe sleeping bag to me, just the ticket for a dp 58 hours in Lapland's freezing rain! Since your record is one for one, I seek your advice again for a compact, light sleeping bag (down is out due to allergies) to use when backpacking in Croatia in August. We'll be sleeping hut-to-hut while walking in the countryside, while also spending some time in cities. Do you think Design Salt's silk liner is good enough for such a trip, or do we need an ultralight sleeping bag? Jan Helsinki, Finland

I would like to know what the difference is between Marmot's 800-fill Couloir and 600-fill Never Summer sleeping bags if they both have a rating of zero-degrees. I'm going to Patagonia in January and would like to know which bag you would use, although I'm not yet sure what elevation I'll be at. Hans Norton, Massachusetts

What's the scoop on Eureka's Zeus EXO line of single-wall backpacking tents? They're inexpensive, light for the square footage, and look to have the se super-quick setup as the larger Eurekas. Do you have any info on how well these tents vent? Bill Charlottesville, Virginia

I'm looking for a boot that is automatic crampon compatible. Also, I'd like it to be a very well rounded boot—I need it to be able to go on extended backpacking trips and even some vertical ice climbing. What is my best choice? Dan Charlton, Massachusetts

What's your take on the soft-shell craze if the activities are both ascent and descent in nature? In other words, I very interested in the breathability for aerobic activities, but concerned about warmth for activities like downhill skiing. Question is, can I have my cake and eat it too? Second, if I can have it both ways, what is your first choice and why? Brad Peacock Medina, Ohio

I looking for a cold weather running jacket that is extremely breathable and wind-resistant (waterproofness is not a necessity). I've been using Lowe Alpine's Adrenaline jacket, which is great for hiking but stes up quickly when I running hard. I usually buy The North Face and Patagonia products but I not sure that they make the best stuff for running. What do you think? Nick Kogevinas Washington, D.C.

I having a very tough time finding hiking boots that are comfortable; they all seem to hurt somewhere. I did find a pair of comfortable trail runners, and I'm wondering if I'd have any trouble day hiking in Glacier National Park using these instead of hiking boots or shoes? How much of a difference is there? Laura Jefferson City, Missouri

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

While preparing for a recent overnight backpacking trip in the Adirondacks, I was surprised at the weight of my loaded pack. Despite having modern "lightweight" gear such as a Western Mountaineering down sleeping bag and the Sierra Designs Clip Flashlight CD, my pack probably weighed 50 pounds. The pack itself, an Arc'Teryx Bora 80, is somewhat heavy, but I needed its size to fit all my gear, including a bear food canister. Do you have any advice for reducing the weight of my pack for an overnight trip?
