Now that hikers are supposed to filter/purify all the water they consume, I'm curious if ANY contact with untreated wilderness water is safe? Is it OK to splash water from a clear stre on my face and arms to cool off? Is it OK to jump in a clear lake for a swim? Would doing these things expose me to infection through ears, eyes, nose, ETC.? What about canoeists and kayakers who are in and around untreated water all the time? Mark Her Fullerton, California

My wife says that my regular reading of your column has cost us a fortune but I swear you've saved me money. Here's a chance to prove your worth, and much more importantly, prove me right. It's spring again, and my Mountain Hardwear Guide pants are suffering from a severe case of "glissade bottom." Are they totaled, or is there a way to economically repair this malady without tossing these wonderful but expensive pants in the trash heap? Secondly, I've tried to prevent "g.b." by pulling a pair of shorts over the pants, but to no avail. The shorts just ride up in to full wedgie mode, leaving me uncomfortable, and the pants largely exposed to the worst effects of snow abrasion. Is there some other method to avoid this in the first place, or should I just buy cheap pants for mountaineering? John Giles Carlsbad, California

Airlines have regulations prohibiting travel with fuel bottles and stoves, even if they're empty and purged. How can you fly to backpacking destinations with white gas stoves and fuel bottles? Do the rules make such equipment obsolete for travel where flights are involved? Fun Walled Lake, Michigan

I guessing that the tool that Bradford Hmar was looking for in a recent question is the Schrade I-Quip (http://www.schradeknives.com). It has an altimeter, barometer, digital compass, watch, whistle, mirror, flashlight, lighter compartment, screwdriver, knife, corkscrew, saw, and scissors. Jason Grech Decatur, Georgia

Great Gear Guru: My hips hurt when sleeping on the ground, whether I've just humped a 60-pound pack or walked into my backyard. I currently use a Therm-a-Rest GuideLite sleeping pad. Do I need a new state-of-the-art pad, or should I just chalk it up to old age? Brad Sioux Falls, South Dakota

I'm going to be spending a year working in Kenya and need to find a sleeping bag. I need to get a synthetic bag, but I want one with mobility since I move around a lot when I sleep. I don't like the constriction of most bags. It also needs to be fairly compact. What do you suggest? Paul St. Louis, Missouri

I camp in the desert in the winter when temperatures can range from zero to 90. My main concern is the wind, which can be downright chilling but also kick up sand. I'm looking for a tent that will shed wind and also not flap like the sail of a 12-meter yacht when it tacks. I'd really like to sleep without the noise. Can you suggest a suitable three- or two-person tent, preferably something on the roomier side? Chip Cairo, Egypt

I just read your reply in reference to a question about sleeping bags for a big guy, and I have similar question. I only five feet, ten inches tall, but I have broad shoulders. I trying to find a mummy bag that is roomy enough through the shoulder area to move in. Do you have any recommendations for good but not too expensive down bags like this? Tad C. Helms Tallahassee, Florida

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

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

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 dumbfounded by all the choices with regard to heart rate monitors. Should I stick with the well-respected Polar or try other brands? Tracy Los Angeles, California

I know it's only August, but I have recently taken up running and looking ahead to the looming Ottawa winter. In preparing to outfit myself, I have been doing some reading about soft-shell jackets. The claim seems to be that I won't need to do the usual layering job with one of these—the soft shell can do it all. Is this right? Would a soft shell be the answer to a big part of my winter running wardrobe? Eric Ottawa, Ontario

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

I 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'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's the best tent for winter camping? I'm interested in a two- to three-person tent that's lightweight, packable, and available at a low price. I will be spending time in northern Massachusetts and the White Mountains this winter. I've been looking into single-pole shelters like the Black Diond Betid ($98), and while comfortable with not having a sealed floor, I worry about water seeping in. Do these tarps really work? Are they reliable? Is it possible to find a reliable four-season tent under $200? Boaz Sender Boston, Massachusetts

I need to find a tent for winter camping and mountaineering. Living in Oregon I intend to stay within the Cascades. I have narrowed my search to the Fusion 2 and the Fury 2, both made by MSR. They fall into the same weight/price/size category. The Fusion is a convertible tent while the fury appears to be a four-season tent. Given the conditions I'm expecting to face, which tent would be the ideal choice for me? Is the Fury too much tent, is the Fusion too little? Is there another tent that you would recommend? Kevin Portland, Oregon

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

What's the best way to clean my hands in the wilderness prior to handling contact lenses? My waterless hand sanitizer warns against eye contact and I don't want to use stream water.

My daughter is flying to Europe this fall and is looking for a good all-around pack for all travel essentials, plus a computer. She is small-fred, five-feet four-inches tall, and weighs 110 pounds. This is the only luggage she is taking and she plans on being there five months. The packs needs to be durable and easy to carry. What should she be looking for? Janet Boise, Idaho

I've collected the very best ensemble of outdoor gear, but I still require one last item: sunglasses! Price is no object, but quality is. I need the best all-purpose outdoor fres that are compatible with prescription lenses. Cebe comes to mind, but do you have any other suggestions? Paul Boulder, Colorado

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

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

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

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

Tent versus tarp? Scott Gillette San Jose, California

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

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

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

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

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

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

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

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

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

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

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

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

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.

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 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

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 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.
