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?

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

I enjoy everything about my new digital camera except for the short battery life, which is especially annoying when on multi-day hikes when the battery might suddenly go dead. Are there any solar-powered products out there for recharging batteries while on the trail? John Swanton, Maryland

I in search of a backpack with a volume of 6,000 to 7,000 cubic inches for a month-long expedition that departs on November 29! Price is not an issue—I'm seeking a good fit for my five-foot-six fre and 17.5-inch torso. The Arc'Teryz Bora 75 women's pack fits well, but the volume is too small. I have also tried the Gregory Denali Pro, which has the capacity but not the fit. Cecilia Canmore, Alberta

I know you're not supposed to store your sleeping bag stuffed, but I need something to contain it in while I not using it. Will a garbage bag work, or should I buy some kind of mesh bag for it? Sarah New Canaan, Connecticut

Will a space blanket attract lightning? Jeff Santa Monica, California

Hailing from sunny California, this is my first year in college in Boston. Here's my situation: New England weather is windy, chilly, and often wet. I need a jacket that will get me through the winter but also look good around town. However, once I buy this jacket, I'll still need money to eat. What can you recommend that won't break the bank, i.e. as close to $100 as possible? Kyle Boston, Massachusetts

I'm fairly well equipped for three-season travel with a Lowe pack, Merrell boots, a Sierra Designs down bag rated to -5, a 3/4-length Therm-a-Rest, and two tents: Mountain Hardware's Glacier and the Slickrock from The North Face. But on a recent June trip in the B.C. backcountry, I pitched the Slickrock on a snowfield and the down bag got wet. What do I do to remedy the situation? Buy a synthetic bag, or a down bag with at least a partial waterproof shell? Buy a full length Therm-a-Rest, which keeps the whole bag off the ground? Get a person four-season tent? Where do I throw my hard earned (and continually depleting) gear dollars? Scott Nelson Vancouver, British Columbia

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

With "just in case" in mind, I like to pack extra food when preparing for a day hike. Pound for pound and calorie for calorie, what's the best emergency trail food? Carrol Phoenix, Arizona

I have a year-old Marmot Swallow that I really love. I spent about 60 nights in the tent last summer and wondering when I might need to think about resealing the ses. I spent a good bit of money on the tent, and want it to last forever. How often is resealing necessary, and can you recommend a sealer? Thanks for your help. Carter Grant Alexandria, Virginia

I'm someone who gets rather sweaty when doing anything active, like mountain biking, hiking, or snowshoeing. During warmer weather, it's not a big deal, but in cold weather it becomes an issue. Whatever combo of base layer, fleece, or shell I try, I still get really sweaty when on the move, especially on my back where the pack sits. Is there some other scenario or clothing combo that I should try to wick out extra moisture Keith Millwood, New York

Can you recommend a good cross-country skiing package that's suitable for both groomed trails and backcountry use? John Duluth, Minnesota

So, what exactly is Scotchgard, and can I spray it on fleece? Terry New Kingston, New York

I a member of Vail Mountain Rescue Group and have been nominated the "gear girl" in charge of finding a good windstopper fleece jacket for our te. We are looking for something comfortable, flexible, and warm, but that's not too bulky and stands up well in the cold (one of our members complained that the Lowe Alpine version gets very stiff in the cold). Any suggestions? Leslie Vail, Colorado

This may be a "gear-related question" with a "you don't need gear for that" answer, but I can't find help on this anywhere. I often hear that running on the beach is one of the most effective ways to boost strength and endurance in your legs. I want to start doing this on a daily basis, and I'm wondering what kind of shoe/sneaker I should you wear. Or do I need to wear anything at all? Mark Brick, New Jersey

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'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

I have been hearing about MSR's lightweight and very compact Pocket Rocket stove. But the fuel for it seems to weigh a lot more than the white gas that I use now for my MSR Whisperlite. Is the fuel for this new breed of stoves heavier than other fuels? And if so why does everyone think they are saving so much more weight when they are making up for it in the weight of the fuel? Justin Strasburg Lincoln, Nebraska

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

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

Can you recommend a trail running shoe that offers good ankle support? Most trail shoes are low- or mid-cut. I have weak ankles from years of basketball (sprains and a few breaks) and I'm looking for a high-top shoe to help prevent ankle rolls. Mark Stubbs Aliso Viejo, California

Do suspension seatposts significantly alter the seatpost height? I currently own a 1997 Cannondale hardtail and I would really like to prevent my spine from someday poking through the top of my helmet. But I'm worried about altering that sweet-spot seat height that has so graciously prevented knee pain thus far during long rides. Preston Fall Vancouver, British Columbia

Can you recommend a sturdy sack that will protect a backpack (with tent and sleeping pad strapped on) when it's checked as luggage on an airplane? David Oakland, California

What's your opinion of the Trailstove wood burning stove for backpacking? Bill Stell Charlottesville, Virginia

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 been searching online for the past few hours for piece of equipment that I believe I saw in some gear magazine (the mail order kind). I will describe it: digital watch, with a compass, stopwatch, etc., and a lighter, signal mirror, and small knife blade with various other attachments. It hung from a lanyard and cost around $100.00 or so. Can you help me find a name for this product or where I might be able to order one? Thanks for the help. Bradford Hammar Charleston, West Virginia

Oh Being of All Gear Wisdom, Following your sage advice, I've been looking for a Yashica T4 point-and-shoot to replace my partner's camera, which bit the Grand Canyon's dust on our last trip there. It appears that Yashica no longer makes the T4. Nor do they seem to have a successor model. What's your current recommendation for either a fixed or zoom lens 35mm P&S? Being a photographic troglodyte, no digital cameras allowed. Rob Brading Fairview, Oregon

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

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

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

Do you know where I can get a bike rack for a Montero 2002 SUV? I don't want it place it on the roof and need it to carry two kid bikes and a mountain bike. Alvin Joaquino Parlin, New Jersey

I'm looking for a new lighter tent as I'm going to be doing some extended backpacking this summer. I'd like one that is freestanding, has a vestibule, and has enough interior space for two people to sleep comfortably. What are the lightest tents in this category? Jim McCreary Cazenovia, New York

I have been looking for a boot that can do it all. From aggressive summer day-hikes to light winter mountaineering in New England. I've been reading all your past articles and the Boreal Bulnes seem to be the ticket, though they seem not to be made anymore. I did manage to find an online retailer with the Bulnes at a great price but I now have a dilemma. How do I pick a size for a boot I can't try on? Since no stores currently carry this boot and the online retailers have questionable return policies, what would your Gearness do? If you wouldn't buy online, do you have any recommendations for similar boots? My anxious feet await your guidance! Matthew Mendonza Boston, Massachusetts

I've been reading your archived responses regarding water-resistant sleeping bag shells with great interest as I'm trying to decide between down bags from several of the companies. After your initial (and maybe continued) ambivalence about Dryloft, I was surprised by your negative view of Epic. Especially since many manufacturers seem to have jumped on the Epic bandwagon as having better breathability. On what basis do you believe that Epic is "a condensation trap" in sleeping bags, and why do you think so many are suddenly using it if indeed it doesn't breathe well? Is it just a fad, too early to tell, or should I stick with Dryloft? I look forward to your reply, if you care to go another round on this topic. No Name Given

I'm a middle-aged backpacker trying to lighten my load. I'll will be "climbing" Mount Shucksan in Washington this summer with a guide. A member of our group maintains that Stubai makes a pair of multi-purpose, lightweight crampons that are great for any boot. I'm wearing Asolo Fusion 95 GTX, which I really like, and these crampons are supposed to be okay for these boots. At best, I'll only be doing one climbing trip per year, but would like a pair of lightweight crampons for crossing the occasional snowfield in the Northwest. What are your thoughts about the adequacy of these crampons (and boots) for a non-technical climb such as the one on Mount Shuksan? Don Uslan Seattle, Washington
