I've been skiing for years and haven't needed to buy new thermal underwear in a long time. But now that I'm ready to replace it, several new materials are on the market. I know I don't want cotton, but what about silk? Wool? Or should I just stick with polyester? y Kuntz California

I'm looking for a mountaineering boot for tackling some of the Lower 48's fourteeners. I've reviewed the Koflach Degre and the Asolo Guide, but I'm also interested in some of the newer leather boots, like the Scarpa Cerro Torre Thermo. Have the new insulated leathers finally become an acceptable solution, or should I stick with doubles? Matt San Ron, California

Are candle lanterns safe to use in tents for light? Obviously you'd want to keep an open fle away from the tent walls, but are they as safe as a battery-powered lantern? John Bergquist Corvallis, Oregon

I'm 55 and like to ride bikes. Here near Lake Michigan in late spring, it's often sunny and cool. I see a lot of die-hard bikers wearing tights, but I'm not interested...is there anything else I can wear? I tried tennis warm-ups, but they're too slippery on the bike seat. Stu Highland Park, Illinois

What's the best crampon for the LaSportiva K3 boot? Can I use semi-rigid crampons with them to climb vertical ice? I need crampons for that and glacier approaches but am afraid that if I get a fully rigid crampon I will get to much balling-up effect with the snow. Joe Roop Prescott, Arizona

I have a 15-year-old Peak 1 stove that still works great. I was wondering if I could use cheaper unleaded gasoline (about half the price of Coleman fuel) without blowing me or my friends up. Or do I need to get a newer model made for both white gas and gasoline? J. D. Craft Lancaster, Ohio

I have a simple question. I dried my jacket on a high temperature in the dryer. Everybody tells me I shouldn't have done this, but how will it affect my jacket? Adrien Lancaster, United Kingdom

G'day Gear Guru, I've noticed a couple of innovative water-purifiers that incorporate the filter mechanism directly into the cap of a light, convenient, and squeezable water bottle. Models by Orinoco and SafeWater Anywhere make lofty claims of filtering and purifying the nasties better than traditional pump-style filters; the SafeWater model even has a filter cap that fits onto Nalgene bottles. Is there any point to lugging around our old pump filters anymore? Lange Sydney, Australia

Oh Gear Oracle, I have a problem with a build-up of moisture within my mittens, not from rain or snow, but from my own perspiration. This is especially true during snowshoeing trips. I was wondering if there are any shells that have little or no insulation, allowing me to layer them inside and increase the breathability of the mitten. Dennis Portsmouth, New Hampshire

Oh Gear Guide, you have failed us! Over and over I have heard you espouse the quality of the Yashica, so I decided that the T4 was the camera for me. Unfortunately, after hours of searching, I find out that the T4 has not been made for years! Just recently, you suggested the camera but didn't mention that it would be impossible to find. With the T4 no longer on the market, what kind of camera would you suggest? Mike Newark, Ohio

At what point, if ever, should your boots be replaced? Is it a question of mileage, time, or condition? I've had my boots (L.L. Bean Knife Edge, leather) for a number of years. They are well maintained and comfortable. Is there a point where the boot does not perform its support function and the trade off between comfort and support (in favor of comfort) is not worth it? Jim Comerford Wyncote, Pennsylvania

Your Gearness, I'm in desperate need of your expert advice. After two major knee surgeries involving saws, metal plates, and screws, I have suddenly become an advocate of trekking poles. I own a set of Master Kompressor poles with comfortable handles and a useful shock-absorber option. However, I've been tempted by a pair of Leki Ultralites, which are six ounces lighter but without the shock absorbers. At five-foot-one and about 120 pounds, do I really need poles with shock absorbers, or is it a waste of money for me? I have my sights set on the Grand Canyon this spring and would like to have time to "road test" a set of poles before then. Paula San Diego, California

I have been trying to decide between the PUR Guide water filter and the MSR MiniWorks, although I have heard that the MSR clogs less and is cleanable. However, the MiniWorks' high pump per liter ratio has turned me off, especially as the PUR Guide boasts a more efficient output. I will be using the filter mostly in high alpine areas where the water is fairly clear of mud and silt. What are your thoughts? Jim Huntsville, Utah

What are the key factors one should take into account in purchasing a road/touring bike? Brent Ithaca, New York

I want a chest pack to carry my Pentax 67II camera and its lens. It will need to have padded shoulder straps and a strap to hold it tight around my waist. Any ideas? Kiim Clackas, Oregon

I've been looking at water purifiers and have narrowed it down to two-the First Need Deluxe and the Sweet Water Guardian. I've read some on both and I've heard of the Guardian breaking on hiking trips and not being field serviceable. I haven't been able to get much info on the First Need Deluxe, only that is clogs. Which do you think is better and why? Kyle Waco, Texas

Is it better to roll or stuff a tent? Kye Eugene, Oregon

I'm considering purchasing a food dehydrator to help lighten things up on long hikes and bike rides. My research suggests that the best options are the erican Harvest or the Excalibur, but I have no idea of how these compare or if there is a better choice out there. I'm comfortable selecting the price and capacity of the model, but at a loss when it comes to the other nuts and bolts of the subject. Do you have any insights that can inform my decision? Chuck Freeport, Maine

Why are mountaineering leather double boots such as the Boreal G1 or Vasque Vertical such a niche product? They are supposed to provide as much warmth as plastic double boots, without any the discomfort of wearing something fit for Frankenstein. These boots have summited Denali and Everest, yet event the "experts" at specialty gear stores frequently don't know about them. What's the catch? Andy Veres Alexandria, Virginia

I'm going on a climbing expedition where we'll be ascending into increasingly colder temps. I'm planning to take two sleeping bags, transitioning to the warmer one as we ascend, then using both at high altitude. Are there any drawbacks or cautions to doing this? How can I estimate the temperature rating of the two bags combined? Vincent Salem, Oregon

What's the best car-camping tent for me, my wife, our daughter, and, if he's good, a dog? We prefer two doors and an aluminum frame, but we're flexible. Henry Davis Willisville, New York

I own a Feathered Friends Swallow down sleeping bag with the regular nylon shell. I was wandering through the gear store the other day when I saw a product by Nikwax that was used to waterproof down garments, including sleeping bags. I would love to give my bag a waterproof treatment to keep the down perfectly dry, but I'm reluctant to do anything to my beloved bag in fear of daging it. What's your opinion of these products? Thanks Mike McLaughlin Pittsburgh, Pennsylvania

I'm looking for a lightweight, compact "kitchen" for holding dishes and utensils while car camping. Can you recommend some sort of canvas or nylon box thingy? Vickey Freedonia, New York

I'm a snowshoer and snowboarder. I wear hard-shell snowboarding boots and I have the step-in type bindings on my board. I would love to find some snowshoes that also have a step-in type binding that would work with my boarding boots so that I could do some backcountry boarding and only need to haul one pair of boots. Any suggestions? Ryan J. Richmond Boise, Idaho

Gear Guy, dress me for kayaking in the marshes of the lower Connecticut River this winter. It's prime roosting territory for Bald Eagles through late February. David Hadd, Connecticut

I looking to purchase a pair of snowshoes and wondering what length/style I should get. I'm five-foot, 11-inchess tall, and weigh about 180 pounds. I most likely will be using the shoes primarily for day hikes so I would probably be wearing a daypack and possibly carrying my skis. Scott Garvin Boston, Massachusetts

From what I've read, your gear reviews are right-on, so I seek your help finding a hydration pack that can hold ultralight gear for overnighters, as well as up to 100 ounces of water. I hope to use such a pack for mountain biking treks as well, so it'll need to have a tight fit and good suspension system. It's proving difficult to find something to meet all these needs, although I noticed you recommended the Ultimate Direction SpeeDemon to a trail runner in January 2003. Is this pack suitable for mountain biking? What about other possibilities like the Ultimate Direction WarpSpeed or the CelBak Peak Bagger? Todd Alpharetta, Georgia

I'm planning to do some solo hiking this summer and would like to take along more than a bivy bag for shelter. I'm looking for a three-season tent that maximizes room (I'm six-feet tall) and minimizes weight. Perhaps a Walrus Microswift or the Sierra Designs Ultra Light Year? I'm not finding too much information or many reviews on the Net, and those that I do find are outdated. Any advice? Don Sherwood Park, Alberta

My girlfriend is hoping to go on a ten-day wilderness orientation trip for UC Santa Cruz put on by Outward Bound. The problem is that she has a bulging disk in her lower back. The sports medicine doc she's seeing says that she should be OK, but I'm not so sure. What are your recommendations for a pack? External-fre packs put more of the load over your hips, right? (She's five feet, three inches and weighs about 100 pounds) Colin Wood Colfax, California

I wondering what binoculars you'd recommend for ge viewing in Africa. This will be for use on open plains and in thick bush, both when I'm on the go and standing still. I'm considering either the Leica Duovid 8+12x42's or Swarovski EL 8.5x42's. Bertus Calgary, Alberta

This past summer I started running and now have continued into the winter. On the longer runs my privates get awful cold. Is there any underwear out there made of microfleece and/or windproof fabric? I run in tights and wear cotton briefs under them. The cotton is the problem. I don't like wind pants or wearing shorts over my tights, but are they the only answer? Tom Faherty Scituate, Massachusetts

I've been looking to buy a (first) sea kayak. I've tried a number of different models and types and have come up with a tentative short list: the Synergy by Northwest Kayaks, the Corona by Perception, the Sirocco by Current Designs, and the Cortez by Dagger. (I haven't tried the last one out yet but I've included it because of Outside's recommendation.) If you were a six-foot, 190-pond guy (and maybe you are) what boat would you consider to be the best value? I'm only considering plastic boats but I want to get the skinny on workmanship, materials, and design. Are these four companies equally regarded? Are the boats? Brian McCarthy Glendale, California

Does anyone make a waterproof tight for inclement weather running/cycling? InSport used to make one, but I guess it went the way of Activent. A European company supposedly makes something called the RaidLight tight, but I can't seem to find anyone who carries it. Erin Skowran Belleville, Illinois

What do you think of OR's Pulsar Parka? I see the Outside Buyer's Guide gave it a "Drool" award. I ask because I can't find it for sale at any of the "big" outdoor retailers. I have hunted every major Web site that carries OR products and not one of them carries or even advertises this jacket. Was there some problem with them or why does no one carry them? Thank you for your response. Craig K. Noble Bliss, New York

What have you heard about the new Eureka Zeus Exo1 single wall Tent? I a big Sierra Design Meteor Light CD fan but need a very lightweight tent for a solo through-hike this summer. Thanks for your help! Lora Cochran Cody, Wyoming

Can you shed some light on headlps for a well-intentioned fanny-pack kisser? I'm after a good, bright headlp for hiking and backpacking. I have an old Princeton Tec Solo, but thinking of upgrading to a Black Diond Gemini or one of the Petzl models. And there I was thinking that the days of headgear obsessions ended with high school. Jay Eugene, Oregon

I'm planning a trip to the Bahas this summer and in the market for a reliable diving watch. Can you recommend something that won't implode after the first ten meters and won't shatter my bank balance? Alison Austin, Texas

My husband and I frequently take our two dogs on our camping trips, in all sorts of weather. However, as much as I love them, after a day of hiking on muddy trails I'm often less than enthused about welcoming two balls of mud into our tent (one 20-pound beagle-ball, the other a 60-pound lab-type-ball). We have daydreamed about a lightweight pouch or lightly insulated sleep sack for our dogs. I ready to start experimenting with my sewing machine, but a friend told me there's a company that makes this stuff. Is this true? And if so, is this gear practical? Toni Schenectady, New York

I'll be going to England, Ireland, and Scotland soon and will spend most nights in my tent or in hostels. My question for you is: what kind of pants should I bring? I want them to look good (since I'll be touring museums and all that), but still be lightweight and durable, since I'll be using these on backpacking trips in the future. I think I've narrowed it down to two choices: Ex Officio Explorer Pants and Royal Robbins's Go Everywhere Pants, but I can be persuaded to change my mind. My girlfriend (who goes with me on many of my trips) thinks zip-off pants look completely dorky, so I'm not interested in those. Thanks for any information! Steve Bockhold Memphis, Tennessee

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

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

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

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

I just recently got into mountaineering and assing all the gear needed to pursue my different interests. I have a lot of the basics and now its time to get some boots. I need a four-season boot for both general mountain travel and technical ice. In the grand scheme of accruing mountain gear, boots account for a pretty hefty chunk of change—especially if you buy three pair of boots: one for three-season mountain travel, another for winter mountain travel, and the third for technical ice. Much more appealing would be a single pair of boots that could do all three. Does such a boot exist? If not, can I get away with two pairs of boots? I'm just looking for a way to escape throwing down $1000 on boots. Josh Hattan Lincoln, Nebraska

I looking for a winter jacket that some may call extreme. I bought a down jacket a few years back that was supposed to be good for -40 degrees Fahrenheit but whenever it is around below zero and a little windy I feel like I have a light fall jacket on. My dre coat would be a down jacket rated to -70 (then I might be warm when it is -10). To top it off I would also like it if it had a fleece liner for extra warmth that I could take in or out depending on the weather. Is there a place that either makes such a jacket or could custom make one? So, I too extreme? Glenn Mulno Needh, Massachussets

I need a bike for commuting that I can use with panniers. Should I go with a traditional touring bike, or should I use one of the hybrids similar to a Trek 7700 FX? I'd like to spend less than $1,250 if possible. I have found some bike commuting pages, but they don't give much guidance on, of all things, bikes. I'm sure you have more than enough time in the saddle to offer some guidance as well as some personal preferences. Tim San Jose, California

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

I'm looking for the perfect sea-kayaking tent. Currently I'm using an older The North Face Geodesic three-person tent: it's great but is on the large size and tends to leak when not staked out. So, I'm looking for something that packs into a small size, can hold more than one person's gear, sets up easily, doesn't require much staking (sand doesn't hold stakes very well), and is very waterproof. Marshall Watkinsville, Georgia

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

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

I just bought new ski boots and I love them. Next on my list is buying new skis. I a solid level-nine skier and can ski anything on the mountain (New England or Rockies), although not always as gracefully as I would like. I love moguls but don't want a ski that submarines in powder. I was looking at the Salomon X-scres but heard that their tails were too stiff and therefore a lot of work in the bumps. Do you have any recommendations for top-of-the-line skis? Will New York, New York

I'm an Australian looking to travel in North America from December to February. Can you recommend a good trekking tent for the season that will house two to three people and their gear? I would like to use the tent year-round and for it to be fairly roomy. Rod Sydney, Australia

What's a good internal-fre backpack for someone just getting into backpacking (two- to four-night trips)? I don't want to spend more than I need to, not knowing how much I'll end up liking backpacking. (I've strictly been a day hiker in the past.) However, I don't want to buy junk that won't work properly and will ruin my trip. Kris Newbury, Ohio

What is the best hat for summer backpacking? Cotton baseball hats are too hot, too sweaty; synthetic caps are a little cooler. But how about a straw hat? In particular, the L.L. Bean Summer Straw Hat that supposedly folds up and packs easily? By the way, your reviews are probably more useful and readable than all the others. Congratulations, and thanks! Marshall Atlanta, Georgia

I'm in need of a bigger climbing backpack, but I'm facing two problems. First, I also need a bigger backpack for weeklong trips; my climbing partner says just get one huge bag, just don't fill it up. So, one bag or two? Second, how big? I a five-foot-six, 130-pound female, and I think I require at least 3,000 cubic inches for my climbing needs. Kendra Boise, Idaho

I've been moving slowly into the lightweight crowd and trying to get my week-long, summertime load below 30 pounds (I live in the Midwest, so a good portion of that is DEET!). I can make it, except for the pack itself. Are there any good lightweight packs? Is this a good place to save weight? Most that I've tried may weigh less, but they make the load seem heavier to me. Tim Taylor South Bend, Indiana

What is your opinion of two-way radios for climbing and skiing? What features should I look out for when selecting one? Tjaard Breeuwer Eindhoven, Holland

I was thinking about buying a pair of convertible pants following a trip to Mount Washington on which the weather went from warm to pretty cold. With a three-day trip planned to the Presidentials this summer, I thought convertible pants might be a good option for any varied weather. What are your thoughts? Scott Cbridge, Massachusetts

I live near North Carolina's Outer Banks and want to purchase a kayak for island hopping. What boat would you recommend for a beginner paddler? Jie Beaufort, North Carolina

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
