I would like some advice on a permanent or removable roof rack, mainly for carrying several pairs of skis on my Isuzu Trooper. Isuzu sells a rack for around $350, but I'm sure I can find something better for the se money or even less. John Boise, Idaho

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

I bought my first pair of snowshoes, and now I need to buy some snowshoe boots. What do you think of Columbia's Excellerator or Bugabootoo boots? Dan St. Louis, Missouri

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

Can you help me choose a boot for a trip to Argentina's Mount Aconcagua? I have summited several fourteeners in my La Sportiva Makalus without a hiccup, but I'm afraid Aconcagua is too much mountain for these boots. We plan on tackling the Polish Glacier route, and I was leaning towards a plastic double boot like Koflach or Scarpa. But, as usual, your input could sway me! Eric Palmetto, Georgia

When out hiking, I'm tired of getting my good-quality boots soaking wet when crossing knee-high stres. Worse still, repeatedly taking off my boots and putting on sneakers or water shoes is a drag, not to mention time consuming. So what's the solution, gear sage? Are there any "water boots" that are sturdy enough to handle trail hiking with a 25 to 35 pound pack, but that can also withstand multiple stre crossings and total immersion? Surely I'm not the only soggy hiker out there. Mitchell Fountain Valley, 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

I recently bought a secondhand Osprey backpack. Every time I use it and break a sweat, I'm overwhelmed with odorous memories of someone I've never met. Is there a way to rid the suspension of the previous owner's "scent"? Stan Gainesville, Missouri

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

What gear do I need to climb K2? Just kidding! With winter fast approaching, I'm thinking about backcountry skiing again. I take avalanche safety VERY seriously and therefore take every necessary precaution. That said, accidents do happen, so I'm looking to buy an avalanche beacon just in case. I'm interested in the Tracker DTS, but how does digital technology fare in cold environments? I've also heard that earlier Tracker DTS beacons had problems with the unit switching to "receive" mode if the wearer's body pushed up against the toggle switch. Is the Ortovox F1 Focus a better, more reliable choice? Michael Vancouver, British Columbia

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 need a thin, lightweight, and durable jacket to keep me warm over a Canadian winter. Problem is I hate fleece and cannot stand to wear anything heavy or puffy, ruling out any down-filled or fleece-lined jackets. I short, too, so no big and bulky jackets either. I know that this is a hard one, but this winter I really don't want to be shivering 99 percent of the time. Tracy Winnipeg, Manitoba

For a four-week section hike on the Appalachian Trail in March, should I get a full-leather waterproof boot like the Hi-Tec Excursion, or the lighter Amazon that's also waterproof and made with both leather and nylon? Matt Chattanooga, Tennessee

I have a weakness for eggs. Love 'em. Don't care what they'll do to me, I have to have them. In the Navy, eggs are coated with a thin wax layer that will keep them fresh for about a month. Can I get these eggs somewhere, or can I do this myself? Also how long will a raw egg stay good when unrefrigerated? I would love to enjoy my eggs no matter how long I may be on the trail. Jes Russellville, Arkansas

Help, Guru King! What's the best trail running shoe I can use when wearing a 30 pound pack and covering around 20 miles a day, on and off trail? I use Vitesse shoes right now, but the bottom of my feet get sore from traveling on rocky terrain. I have been looking at a number of brands and have tried calling their product develoent divisions—but it's hard to contact those folk! Peter Belmont, California

What's the story on titanium cooksets? A friend of mine has one from MSR and while it's super light, it doesn't seem to heat up as rapidly as my stainless steel set. I like the lightness of titanium, but if I have to bring 50 percent more fuel to cook with, I'm not sure it will be worth the price premium. Steve Young Mountain View, California

Do you think the Bibler's Tempest is too much tent for Oregon's Mount Hood? I'm looking for a four-season tent in the $400 to $500 price range. I plan to live in it for a while (at least three to four months) as a volunteer. Joe Venice, 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

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 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

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 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

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

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

I've read your praise for the Yashica T4 point-and-shoot camera and was attempting to locate a refurbished unit on the web, when, lo and behold, up pops the new Yashica T4 Zoom with a Carl Zeiss Lens (28mm to 70mm). In the wilderness, I've always managed to catch more pictures than fish, and would appreciate your thoughts on a lightweight point-and-shoot for my arduous outdoor adventures. Scott Maple Valley, Washington

Man, do I need some bike advice. I have been riding mountain bikes exclusively for the last ten years. I now want to buy a road bike specifically for commuting and exercise. I would like something fun and comfortable to ride, but geared like a road bike for speed. I considering the Marin Tiburon and the Specialized Sirrus Pro, which are in my price range. What should I go for? Lawrence Elk Grove, California

I am looking for a tent that will repel dew, especially as I hate the damp feeling that comes from wet grass. Which tent do you recommend? I don't do much camping, but I do like to be comfortable when I do. Tara Bowler, Wisconsin

I know nylon fabrics deteriorate from too much exposure to the sun, but does nylon lose its strength from old age? Is a sleeping bag that has been in storage for 20 years without seeing one ray of sunshine still "as good as new"? Are there both "good" and "bad" quality nylon fabrics, or are they all made equal? David Sparta, Michigan

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

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

I've been looking for a zero- or minus five-degree sleeping bag for use in early spring, but found that nobody makes any quality down bags for women. What's up with that? All Western Mountaineering bags are huge, while Feathered Friends makes only two women-specific bags, but they're rated only for 10 and 20 degrees. I just wonder, does the outdoor industry think that every outdoorsperson is some huge guy with wide shoulders and skinny hips? That has got to change! Anyways, for the problem at hand: I'm five-foot-six and on the lean side. What's a quality down bag that won't require me to expend extra energy in order to heat up excess room inside the bag? Jennifer San Diego, California

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

Please explain the new REI One Jacket! I saw it advertised as a single-layer jacket to replace multiple layers, so I tried one on the last time I was in an REI store. Problem was that it comes with no hood and the pockets are so low in the hip belt area. It doesn't seem comfortable enough to wear without a light layer, or waterproof enough to ditch the rain layer. So, what exactly does it replace? Chris Silverdale, Washington

I accidentally burnt a hole, about one and a half inches in dieter, in my Western Mountaineering Dakota sleeping bag. I'm having trouble finding a place to repair it, and I don't want to do it myself because a brand new bag with a 30-year life span should not have some junky patch on it for the remainder of its working days. Ross Reading, California

What's the difference between Atlas Dual Trac snowshoes (they appear to cater to racing) and the all-purpose 10 Series that is designed for hiking? Can you use dual track shoes for hiking, or are they simply a high-performance marketing gimmick? Stephen Seattle, Washington

Any idea where I might look for prescription sunglasses that I could use at high altitude? My local optician says the lenses he could sell me "might" block both ultraviolet (UV) and infrared (IR) rays, but he's not sure. Is blocking both UV and IR really important? Andy Billings, Montana

I have a Gore-Tex Mocha jacket, which is about seven years old and seems to repeatedly lose its water repellency. I have treated it with Gore Revive-X several times, but there are only a few areas on the coat where water beads up, and even then not for long. As a result, I often feel clmy if it's raining hard, although I don't think I'm actually getting wet from the outside. Does Gore-Tex have a lifespan, after which it's not that great even if you keep treating it? Basically, is it time for the old Mocha to be replaced? Karen Wellington, New Zealand

What's a good, moderately priced tire for mountain biking in the snow? I'm not looking to spend a fortune for a studded snow tire, just something with better traction that I can use in the spring as well. Paul Patterson, New York

I just bought a pair of glacier glasses on eBay that don't have a brand, but they do have side shields and the lenses seem quite dark. However, I don't know how powerful they are at blocking ultraviolet light. Would these be suitable for a trip to Mexico's Pico de Orizaba? Eric Plymouth, New Hampshire

Is it necessary to waterproof Gore-Tex boots with something like Nikwax's Aqueous Wax Waterproofing? Mike St. Paul, Minnesota

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?

Is it necessary to waterproof Gore-Tex boots with something like Nikwax's Aqueous Wax Waterproofing? Mikebr>St. Paul, Minnesota

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

If I want to go mountaineering up here in the Northwest, is it enough to slap some crampons onto a pair of Scarpa Rios? I know Rios are great for just about everything else and that they stopped making the Edwardo climbing boot (why, I don't know). Or, should I try some other boot? Jim Trueworthy Coeur d'Alene, North Idaho

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'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'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

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 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

Why did Sno-Seal fall out of favor? I kept a pair of heavy hiking boots alive for years with some welt dressing and this stuff. Joe Midland, Texas

I know you get lots of questions about the best outdoor cameras, but can you recommend a camera that operates well at high altitudes (above 20,000 feet) and in extremely cold weather (around minus 50). I have heard that autofocus doesn't work above a certain elevation. I'm looking for a compact or SLR that is lightweight, resilient, with easily accessible batteries (for efficiency when changing them in the cold), and which will capture the highest-quality images at the top of the outdoor world. Sarah East Lansing, Michigan

My ne is George, and I a Gearaholic. I know I have a problem, but I cannot control myself. Although I have eight packs, ranging from a Gregory Denali Pro to a Mountainsmith Ghost, I have the se dilemma with all of them. Though of average build, my hips are non-existent, causing my hipbelts to slide down my waist. This problem can be very bad in winter when lugging a heavy pack and wearing slippery Gore-Tex clothes. Are there any gripping solutions that can be applied, or is there another pack that can cure my problem? George Rochester, New York

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

OK, so jogging on the trail with a baby isn't safe. But, I would like to go backpacking after our baby is born. Are there any all-terrain strollers suitable for trails? I know there are baby carriers to wear, but dad still has to carry the rest of the gear, doesn't he? M. Dittman Cleveland, Tennessee

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

This summer, I will be traveling in Peru and concerned about thieves cutting into my pack. What do you recommend to protect my belongings? Pat Harlingen, Texas

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

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

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

I need a very lightweight tent for extended hiking trips on the Appalachian Trail. I carried the Marmot X-Racer last week and ended up with knee problems, so I'd like to shave off three to four pounds if possible. Is there a single-walled tent weighing around three pounds that uses trekking poles for supports? Matt Chattanooga, Tennessee

Your Gearness, I planning to drive cross-country this summer, hiking and camping wherever the road takes me. For the driving portion, I was thinking of investing in a GPS system to help with the "figuring-out-where-the-heck-I-am" moments. Do you have any advice as to the value of GPS for this? (I will not need it for hiking, using the old-fashioned technique of map, compass, and trail blazes) Realistically, I'd like to stay under $300, but will go higher for an exceptional device—one that does the navigating, driving, AND laundry. Charles New York City, New York

I often ski and snowshoe in the Adirondacks backcountry, but my back always gets soaked under my pack whenever I'm going uphill. I have tried different layers to avoid the wetness, all to no avail. What do you recommend to keep my back comfortable? Ian Lake Placid, New York

I'm planning on through-hiking the Pacific Crest Trail and would like to keep my pack weight as low as possible without sacrificing comfort. When I through-hiked the Appalachian Trail in 1990, my pack weight was around 50 pounds, including food and water. I have heard that ultralight packs are not very comfortable with loads over 20 pounds. Can you recommend a lightweight backpack for my hike? Cliff Ashford, Alabama

I desperately trying to find a bright hand torch that does what the manufacturers claim—I've bought three torches this year all because they told me they were bright, only to discover, to my disgust, that they were hopelessly poor. Can you recommend a very bright hand torch that doesn't take six batteries like the Maglite and doesn't weigh a ton? Kevin England, United Kingdom

When I was getting ready to apply mink oil to my two-year-old Asolo boots, I found the inside lining around both heels had split and the fo lining was coming through. These boots haven't seen extensive service, only being worn for school. The store where I bought them is out of business, so whom should I contact to get them fixed or replaced? Dennis Cedar City, Utah

When it comes to packing a backpack, I get lots of varying answers. What's correct, the weight at the top of the pack or at the bottom? Kristen San Diego, California

For the man who has every item of biking gear imaginable (judging from the mountain bikes, panniers, and lights littering our garage), what's the perfect Christmas gift for my husband, one that will even have Santa's elves guessing? I'm looking to spend up to $100. Janet Atlanta, Georgia

What's going to be the coolest new gear for 2003? The reason I ask is that I want to buy my boyfriend a really unique Christmas gift. He loves the great outdoors, but is still using his ten-year-old boots and ratty old backpack when we go hiking. I know he'd love to be the coolest hiker on the trail! Caroline Santa Fe, New Mexico

I'll be skiing in the Austrian Alps this winter. What's the essential gear for avalanche safety? We're not all supported by James Bond-level technology, but I was wondering what sort of equipment you'd recommend for going off piste. Brian York, United Kingdom

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

Is there a liquid-fuel stove that gives out good heat, but that is also quiet and compact? The MSR Dragonfly is fine heat wise, but it's incredibly loud. The Optimus 111C is hot and quiet, but it's too bulky. Bruce Oakville, Ontario

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'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

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

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

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

I'd like to buy my dad a comfortable bike for exercise and recreation. He doesn't like to be hunched over a bike because he has a temperental back. He also needs a comfortable seat. Is there anything for $800 or less? Joe Edison, New Jersey

I bought a Marmot Massif XL sleeping bag because I'm somewhat claustrophobic and wanted a high-quality down bag with ple room. While it indeed has plenty of room, the extra space makes it far less heat efficient—it's rated at ten degrees and I'm barely warm enough at 25 degrees. What kind of liner would you recommend to add warmth for colder nights but not defeat the purpose of getting a larger bag? Neal Pratt Portland, Maine
