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

On a recent spring trip to snowy Mount Whitney, I took a gble and wore my comfy Sundowners along with a pair of Wild Country gaiters, instead of plastic boots. But, the front part of the gaiters kept slipping up and my boots quickly got soaked with all the postholing. Do you think a regular boot and gaiter combo can replace plastics (too heavy and uncomfortable) for snow travel? I'm talking multi-day trips in the California Sierras here. Jake Irvine, California

Gear Guru, what eye gear do you recommend for cross-country skiing when it's windy and snowy? Every pair of goggles I own fog up when I cross-country skiing or snowshoeing. Would glacier glasses solve this problem? Craig Portland, Oregon

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

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

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

I 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. 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

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

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

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

As a frequent trail runner, I looking for a backpack designed with running in mind. I would like something with ple storage for additional layers and supplies, certainly larger than a lumbar pack. Any suggestions? Connor Ann Arbor, Michigan

I starting to gear-up in preparation for climbs of Mount Baker and Mount Rainier this summer. I have an older Princeton Tec headlp that I use for backpacking, but can you recommend a good replacement? Are any of the newer LED headlps good enough to use when climbing? Kleet Renton, Washington

I have Scarpa T1 boots and have noticed that my ski edges are going to massacre my boots if I don't protect them. A solution I have heard of is to wear "supergaiters" with either Kevlar or other sturdy material on the instep to protect the inside of the boots. Unfortunately Black Diond (she on them) no longer makes a supergaiter and the Outdoor Research X-Gaiter is overkill in that it is expensive and so insulated that it will cook my feet. Any advise? Bill Hirshberg New York, New York

I'm staring down the barrel of a long, cold, wet winter, which will put a crimp on my outdoor bicycling. Now, I can't afford a house big enough to install a velodrome, so I'll need to purchase either a trainer or rollers to ride my bike inside. Should I fear the rollers? Will I need to put fo padding all around them? Will true believers mock me if I buy a trainer instead? Glen Novato, California

I looking into buying a soft-shell jacket and interested in the Cloudveil Serendipity, the Arc'teryx Gma, and another jacket from Salomon. What are your opinions on these jackets and are there any others that I should consider? Mike Kane Rock Island, Illinois

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Dear Gear Guy, can I extend the life of running shoes by using Dr. Scholl's gel insoles? Will they improve the comfort of hiking boots? By the way, I use orthotics. Gary Goins Denver, CO

I'm planning a mountaineering trip to Bolivia in June. I have a pair of Koflach Degre boots, which have been fine on Mount Hood and when winter climbing in New Hampshire. Will these be OK for climbing Bolivia's 19,000-foot peaks? Do I need Alveolite liners? Brian Augusta, Maine

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

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

I'm wondering if you know the difference between all the soft-shell fabrics, specifically Power Shield and Schoeller Dryskin. Also, what's the deal with the ultralight rain shells like Patagonia's Microburst or Arc'Teryx's Sirrus SL? REI's Web site used to say that Sirrus SL is "truly an ultralight shell, thus should not be for everyday use." Are they suggesting the ultralight jackets are not that durable? Does it make sense to carry both a soft-shell and an ultralight rain shell on a long backpacking trip? Jenny San Diego, California

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

I'm interested in buying a new kayak for touring and open-water paddling, but one that could also take a little whitewater action once in a while. What would you recommend? Jeff Midland, Michigan

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

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

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

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