On a recent winter excursion in the Adirondacks, my Whisperlite stove failed. The fuel was pressurizing, but it wasn't reaching the ignition wick due to a blockage in the fuel line. Why does this happen in cold weather (our temperature was in the single digits), and how can it be prevented? John Buffalo, New York

I'm beginning to think that today's trend toward Assos-esque padded cycling shorts—padding formerly being the saddle's job—has left me with more saddle sores. This bulky new style only serves to form a bulk of soggy material once the sweat soaks through, causing blisters and general discomfort. Does anyone make shorts or bibs with either minimal padding or something akin to the original chois style? Between the incontinence of infancy and agedness, I prefer not to wear a diaper while riding. Can you help? Clay Wimberley, Texas

I have been backpacking and hiking for many years but I was recently told that for long hikes I should put on my liners, spread Vaseline on them, and then put on my hiking socks. Do you know anything about this or is this a joke? Joaquin Lira Oshkosh, Wisconsin

I'm going trekking around Mont Blanc and have been told not to drink any glacial meltwater because it contains tiny sharp particles of rock, called talc, which can shred one's insides. I have an Aquira water bottle with a two-micron filter, which is supposed to remove microscopic pathogens. Will it stop talc? Hal Berkeley, California

I've been shopping for a car-camping tent for our family (myself, my husband, two kids aged 14 and nine, plus one growing golden retriever puppy). I want a three-season tent that gives us a fair amount of space, maybe with dividers, but the mind boggles with all the choices: nylon, polyester, taffeta, fiberglass, aluminum, this D mesh, that D mesh. I feel like I need a degree in materials engineering to figure this out! Can you help? Tracey Irvine, California

Sage of swag, I'm in the market for a road bike, and looking for direction. Initially, I'll be using it for fitness riding, but I anticipate riding in local road races in the future. I'm a family man with a limited budget for recreational toys. That said, I want something that's going to stand up—a bike that I won't have to replace or extensively or upgrade as I get into the sport in a bigger way. Is a bike equipped with Shimano 105 group the "minimum" I should be looking at? Which models should I be considering, and at what price point? Greg Basky Saskatoon, Saskatchewan, Canada

I'm planning a through-hike of the Continental Divide Trail this summer, and I want to go ultra-light. What's the best tarp to use—the easiest to set up, the best in wind, and so on? Syd Seattle, Washington

Great burning bush of the gear desert, Marmot Precip hat or urban sombrero? I want to buy a good waterproof hat; hoods are cool and all, but they're sometimes a pain in the fanny pack. I have read that you often prefer hats to hoods. So, would you choose the Marmot Precip Safari Hat, the Outdoor Research Seattle Sombrero, or something different altogether? Please help me before I do something dumb—like ask someone else. Jay Eugene, Oregon

I'm a big guy (six feet five, 270 pounds) who's interested in buying a hybrid bike for some urban biking and trail riding (nothing too extreme or competitive). So I need a bike that fits but doesn't cost a fortune. Also, can you explain mountain- and hybrid-bike sizing conventions, especially as there doesn't seem to be a standard way of measuring hybrid bikes?

As a thrifty person with only occasional needs for real cold weather gear, I'm tempted by the down jacket that Land's End sells for $70. Pretty simple design, 650 fill, seems like something that's pretty tough to screw up. Any experience with how this jacket stands up to some of the pricier down parkas from the more traditional gear makers? I'd be using it for an around the cp and belay over-jacket in the Sierras. Raymond Tarto Oakland, California

I want to buy a bike to ride the two miles to work and head downtown on the weekends, about a 15-mile ride. Thing is, I have an attachment to big comfy handlebars, seats, and three-speed internal gears; I cringe at all the "touring" bikes with their rock-hard seats and hunched-over handlebars. I currently have a cruiser and walk it up hills. Can you recommend a bike that won't break the bank? Tiffany Santa Barbara, California

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

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 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

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

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

I want to take my video camera with me on a trip to the Colorado mountains and hoping I can buy a solar panel to charge the battery. There seems to be some difficulty with finding info. It's a 6-volt battery and I have the adapter that plugs into a car cigarette lighter. Can I buy a 5-watt solar panel that is advertised to charge a 12-volt car battery and use it? Can I just wire up the cigarette lighter receptor to the panel, and then plug the adapter into it? Seems to me that ought to work. But, we don't know much about solar panels other than expeditions use them to charge batteries. Jeannette Singleton

I have never spent a night on the trail, sticking to day trips instead. However, it's something that I think I would like to get into. My hiking partner has the tent, stove, and first aid kit. I don't want to go out and buy all the other equipment (sleeping bag, pad, boots, etc.) until I certain that backcountry camping is for me. What would you suggest for my first trip? . Melissa Greenwood, Delaware

Can you recommend a three-season tent that is well configured and roomy for two people and a dog? Tom Miller San Francisco, California

To revisit the sleeping naked debate [June 12, 2003: "Is it true that it's warmer to sleep naked?"], I'd like to point out that while sleeping with a lot of clothes on should generally be warmer than sleeping naked, too much clothing might compress the sleeping bag's insulation and somewhat impede blood flow, resulting in a colder sleep. Wouldn't you agree? Stephen Calgary, Alberta

Most high-end down sleeping bag manufacturers state that THEIR shell material is the best for both breathability and water and wind resistance. After reading the specs on all the different shell-fabric brands, I'm left feeling dizzy. A friend says that Gore DryLoft is best, but then other reputable companies say Conduit, Hyvent, G3, Pertex, or Epic is better. Help! Which one would you choose? David Sparta, Michigan

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 have recently begun rock climbing and have decided it is time to purchase climbing shoes (I sure that this isn't another phase for me like decorative soap making). I have been told and read that when purchasing climbing shoes to buy them one and a half sizes smaller than your regular shoe size. Will they really stretch one and a half sizes lengthwise to fit my foot, or will I just be inflicting some strange foot torture on myself? Thanks! Matthew Cpion New York, New York

I have been happily skiing and snowboarding in my Patagonia Nitro II pants for the past few years. However, having recently signed up for a mountaineering course, I was told they aren't designed for mountaineering because of their two-ply, mesh-lined material. I'm confused as to why pants perfectly fine in a skiing environment can't work for mountaineering. I don't want to shell out $300 on another pair of pants! Ken Toronto, Ontario

Can three-season tents be used in the snow? Is it necessary to have a "mountain" tent for snow camping? With a full cover fly, what is wrong with using a three-season tent for occasional snow camping? Lyn Greenhill Roseville, California

I looking for a new lightweight backpack. I never carry over 30 pounds and had decided on the Gregory Reality until I found a new Mountainsmith backpack called the Mountain Guide at a local store. The salesperson told me it was brand new and can't find any information about it. She weighed it for me as the specs didn't include a weight and it ce out about two pounds lighter then the Reality. Does two pounds makes a huge difference in a pack? Kjaristy Salt Lake City, Utah

I recently purchased quite an expensive digital camera. As I'll be backpacking in Montana's Crazy Mountains this June, I'm wondering if it's practical to bring the camera along. If so, what type of bag or protection should I purchase, and where is the safest, yet most accessible spot in my pack to store the camera? Kristin Eden Prairie, Minnesota

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

Backpacks are a bit of a problem for me because I rather well endowed and the straps get pushed out onto my arms when walking—with all the consequent chafing. Can you recommend a pack with front crossover straps, or an alternative that leaves me unchafed? Deborian Boca Raton, Florida

Where can I find a waterproof video camera, for filming surfing and other stuff? Luke Ft. Myers, Florida

We know your favorite sub-$500 camera is the Yashica T4 Super. But, what are your favorite point-and-shoot cameras for $500 and above? Roy Boston, Massachusetts

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

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

I need a good solo tent in the $200 price range for winter mountain climbing trips. It seems that manufacturers have come out with many new solo tents, but I can't tell if any of them would work for winter camping. Mike Rapid City, South Dakota

In southern California the sun is out and the hills are green. Yes, it's almost spring, the time when a young man's fancy turns to...cycling. My helmet is several years old, and I think it's time to retire it. Thumbing through a number of catalogs, I can't believe the wide range of prices. Just what the heck does $200 buy me that $40 doesn't? Larry Long Beach, California

This summer I plan on taking a backpacking trip to the Selway River or Kelly Creek in Idaho. I hope to do some fishing as well, which will require wading in the river. I do not want to take wading boots due to the weight. Do you have any recommendations for sandals or other footwear that can serve as both hiking sandals and water sandals? I need good sole support for hiking and walking over boulders while wading. I also require a non-slip surface that will grip wet rocks. I have found that hook-and-loops material does not work well when wet. Last summer, the hook-and-loop straps kept coming undone on my Tevas. Any help is greatly appreciated. J.L. Walker

I'm looking for a women's pair of insulated, waterproof or Gore-Tex, crampon-compatible hiking boots. I'm not climbing Mount Everest—what I'm looking for is a boot to get me through the winter when I don't need snowshoes, but it's freezing out and I may need crampons. (Specifically, in the High Peaks area of New York.) I'll be using them for long hikes on paths and over rocks. I don't seem to be able to find the perfect combo as most options seem to be heavy-duty mountaineering types. BJ Guilderland, New York

For a few years I have been using a Macpac Microlight tent, perfect for me and my pack. However, I'm now looking for a slightly larger tent to also accommodate my dog. Finding that Macpacs are not sold in this country and mail order prices are exorbitant, I was wondering what you'd recommend that's comparable in durability, waterproofness, weight, and quality, hopefully for a more reasonable price. Jennifer Seattle, Washington

I live in the city and looking for a bike that I can ride to my local bike trail via city streets (approximately three miles). The trail is dirt and gravel, but I'll also need front suspension because of reckless drivers who sometimes force you onto a sidewalk. I have been to several bike stores and really confused by all the options: Raleigh C500, Cannondale, Giant Cypress LX, Trek? One store advised me to wait until mid-August for the 2004 models to arrive in stores. My budget is $500 to $600. Chris Philadelphia, Pennsylvania

I'm planning to climb Aconcagua next year followed by Denali the year after, and I was wondering about layering for warmth using down sleeping bags and parkas. I want to avoid buying really specialized gear (like the Feathered Friends Rock & Ice Parka, or their Snowy Owl bag) that I can only use on the coldest peaks like Denali. Is it possible to achieve a comfortable temperature rating on this mountain using a combination of the Icefall Parka and the Widgeon bag? The reason I'm asking is I would like one bag for all my mountaineering endeavors (including the not-so-cold trainer mountains). John Toronto, Ontario

I wear prescription lenses in my sunglasses and want to get a similar custom-made pair of glasses for paddling at night. I've heard that a yellow tint on the lenses helps to bring out objects. Is this true? Is there anything else I should consider when ordering this pair of glasses? Dennis Milton, Florida

I'm going to Alaska's Denali in June, so are there any particular jackets out there that you would recommend? Would the Marmot Parbat Parka be sufficient on a breezy day atop Mount Denali? Eric Maryland

How do you know when it's time to replace your running shoes? I have been road running on a pair of New Balance 804s for about a year. I weigh 200 pounds and run about two to three miles five days a week. Any suggestions for new shoes? Craig Portland, Oregon

My son and I need to purchase raingear for an eight-day canoe trek to Minnesota's Boundary Waters Canoe Area this July. Do I need to get a Gore-Tex parka like most people recommend, or are the newer, lighter styles like Marmot's PreCip enough for such a trip? David Wichita, Kansas

A friend suggested that I extend the life of my leather hiking boots by proactively applying se-grip to the stitching and the area where the upper meets the sole of the boot. Is this legitimate advice or have the petroleum distillates simply gone to his head? Chuck Freeport, Maine

I sweat a ridiculous ount and have no problem staying warm, having nordic skied in sub-zero temps wearing only a thin nylon T-shirt and XCR shell. So, I'm in search of the ideal base layer shirt. I like Patagonia's lightweight Capilene, but I'm still experimenting with various fabrics and manufacturers. I'm skeptical of Patagonia's silkweights as the stitching across the shoulders looks like it would be irritating with a big pack on. Do you have any wisdom to impart? Seyil Toronto, Ontario

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

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

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

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

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

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

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

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

There is a UK firm called Snugpak that makes equipment for both civilian and military use. Some of their sleeping bags are made with a Pertex shell and a special type of fill that is supposed to be both a good insulator and compress very well. They claim some of their sleeping bags (rated to minus 58 degrees Fahrenheit) will compress into a very small package and weigh only a few pounds. Is Pertex a good product and does Snugpak's down-fill live up to its promise? Are their products worth the money? Mark Tucson, Arizona

I'm looking for a decent sleeping pad to use when backpacking. Cascade Designs' Therm-a-Rest seems a good buy, but I'm not sure. Does the three-quarter pad mean my legs will be hanging off the end? Does that even matter? What are the benefits of the larger, wider pads versus the ones that fold in half length-wise? Matt Albuquerque, New Mexico

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

What do you recommend for mountaineering in places such as Mount Rainier and Denali as far as headlps and bibs or pants? Would an LED light be better than a regular headlp? I know LED lights last much longer, but what about lighting up the trails? Also, are there any three-layer bibs that you would recommend that are warm, durable, and inexpensive? I like the description of the Marmot Alpinist but it's quite expensive. Are there any less expensive options? Charleton Churchill Pine Grove, California

What is the best type of footwear to wear when snowshoeing? Do I wear my hiking boots (kind of stiff but durable)? Or my low-cut trail hikers (comfortable but less durable)? Or something else? Katie Gold Boston, Massachusetts

I considering buying a pair of hiking shoes for day hikes with a light load (usually my 30-pound daughter in a child carrier). I have a pair of Merrell hiking boots and tennis shoes and I find both too warm (I don't know if its just me but I find tennis shoes very warm even though I don't have a tendency to sweat). Hence, I always end up using my Teva sandals, which don't give me enough support and don't protect my feet. Can you propose a closed hiking shoe that won't make me feel like my feet are in a furnace? Thanks in advance. Guillaume Frechette Columbus, Ohio

Dr Gear Guy, please realize that you are completely indemnified from any liability as to the efficacy of your answer, but I'm wondering what gear you'd specifically recommend for a hiker who has undergone a total hip replacement and refuses to cast a deaf ear to the call of the wild? I have a pair of good trekking poles. Anything else come to mind? Keith Columbus, Ohio

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've been looking for a lightweight, water-resistant jacket for hiking and mountain biking. I've been looking at the Patagonia Dragonfly Pullover, which is advertised as water-resistant, very light (3 oz), and compact. It is also rather expensive ($135). Is this jacket worth the money? Are there any other jackets this category that you would recommend? Chris Newark, New York

My wife and I will be hiking in the Canadian Rockies this summer. We'd each like to carry a pair of compact binoculars for birding and the occasional vast vista that we might come upon. Without breaking the bank (we don't need waterproofed and rubber-armored), what would you recommend? As far as magnification goes, should we consider buying zoom binoculars or stick with a basic model? Also, how important is it to have the widest field of view possible? Byron Phoenix, Arizona

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

I new to whitewater kayaking and was wondering about a practical, fairly inexpensive way to get into the sport. Jimmy Cullowhee, North Carolina

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

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

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

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

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

What's a good trail-running/adventure-racing shoe for an over-pronating runner like myself? I need to buy a new pair of shoes quickly! Rob Indianapolis, Indiana

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

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

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

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

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

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

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

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