I've heard that under non-extreme conditions my hiking pole can be used as a self-arrest tool when crossing steeply inclined snowfields. As much as I would love to buy an ice axe and add it to the chaos of my gear closet, I don't want to purchase an item when an existing tool would work just as well. Should I indulge my gear habit or stick with what I've got? PG Hancock Littleton, Colorado

Hola Señor Gear: After ten days of tromping in the Peruvian rainforest in borrowed rubber boots, my insteps are bruised from roots and stumps and my toes want to grip the inside of my shoes for stability. Yet, I'm convinced that rubber boots are the only way to go in jungle conditions. Are there rubber boots with hiking boot soles and at least a little support for the ankles? Bob St. Louis, Missouri

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

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

I have a 2001 Honda Civic coupe and will be making a cross-country trip. I looking into a cargo rack to outfit my Civic but I'm not sure how much to spend and which brand to go with (Thule, Yakima, or Saris.) The rack will probably only be used for a rooftop storage bag. If you could suggest a rack model I would greatly appreciate your help. Pete Lptey Fairfax, Virginia

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

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?

My wife has been using a pair of Asolo AFS Ridge boots for our backpacking trips, typically extended ones through rugged terrain. The Asolos blew out a se in front of the laces and need to be replaced. We are considering the Montrail Moraines or the Asolo 520 GTX boots. Is the Moraine too much boot? Is the Asolo 520 enough boot? Any other suggestions? Louis Oregon City, Oregon

Being from California, I do the majority of my hiking in the Sierra Nevada—"park bear" country. As bears become smarter, hanging food becomes exponentially less effective. I hate to carry those heavy canisters. Does anyone make a titanium canister, or an ultralight canister, being that Ursacks are not allowed in Yosemite or Sequoia National Parks? Michael Santa Clara, California

Your Gear Excellence, What would be your recommendation for footwear to run in the rain? Living in Mii, and especially at this time of year, it's a pain to have to cancel my morning runs. However, I concerned that hitting the asphalt sidewalks under pouring rain with my regular Asics or New Balance running shoes will give me blisters. Are my concerns well founded? Do I need special footwear to run under the rain? Gotta go for my run. Andres Biernat Mii, Florida

I have a bit of a problem. I must have put my pack away a little wet after a spring backcountry ski trip and now all the waterproof coating is coming off the inside of the pack. I have a siliconized nylon pack cover that I will probably use for an upcoming Sierra trip and sprayed the outside of the pack with Nikwax. I also always use a garbage bag inside of the pack to protect my gear. Do you think the pack is done and I need to bite the bullet and buy another? Or do you have any suggestions of ways to fix it? Tim Newport Beach, California

My fiancC) has an old REI dome tent that she loves and always insists on bringing, though I'm convinced, because of its age, it's destined to soon become just some tattered prayer flags along the trail and leave us shelterless. She doesn't like any of the current tent designs because their vestibules completely protect the door and prevent you from being able to easily watch the rain. The REI dome is great because its door has two parts—a screen door and ripstop nylon door that you can zip part of the way up to keep rain out. Does anybody still make a dome tent like this? Mark Scantlebury Portland, Oregon

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

My daughter is flying to Europe this fall and is looking for a good all-around pack for all travel essentials, plus a computer. She is small-fred, five-feet four-inches tall, and weighs 110 pounds.

I need to find a tent for winter camping and mountaineering. Living in Oregon I intend to stay within the Cascades. I have narrowed my search to the Fusion 2 and the Fury 2, both made by MSR. They fall into the same weight/price/size category. The Fusion is a convertible tent while the fury appears to be a four-season tent. Given the conditions I'm expecting to face, which tent would be the ideal choice for me? Is the Fury too much tent, is the Fusion too little? Is there another tent that you would recommend? Kevin Portland, Oregon

How do you clean and wash boots? I have a pair of Asolo Cerro Torre's, and they are fairly light boots, but after a trip in the Never Summer Wilderness with lots of rain and mud, they feel heavy. The dried mud adds up, I guess. How can I make them light again? Thanks. Josh Wheeler Denver; CO

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

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.

Helms Tallahassee, Florida

Hello Mr. Gear, I'm going to the Arctic National Wildlife Refuge late August/early September this year. Since the place is beyond the Arctic Circle and the timing is going to be late, I wonder if my insulating jacket—a Wild Things primaloft sweater—is going to be warm enough. Also, what's the difference between a three- and a four-season tent? We're trying to decide on a tent to take along, but I wonder if I should take a four-season tent. Last year we took a Sierra Designs Meteor Light to Alaska, but it really didn't perform under the gusty conditions. And this year, we're expecting very very windy conditions as well. Is there any three-season tents that can live up to gale force winds, or I'm just stuck w/ the dead weight of a four-season tent? Blanche Ingr Brisbane, Australia

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

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

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

I just returned from Mount Rainier with a rope I had bought specifically for this trip but with the intention of using it for rock climbing. I hate to think of the number of times I saw it go under foot. None of my ropemates put a crampon into it, but I sure don't see myself taking a lead fall with it now, especially 100 feet up. But what about glacier travel? Certainly the guides on Rainier leading newbie mountaineers don't replace their ropes after every trip. Is there anything I can do to physically check the condition of my rope and feel comfortable using it for glacier travel? I truly hate to toss a rope after one trip.

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

What's the deal with siliconized nylon? Smaller companies like Integral Designs, Six Moon Designs, and Wanderlust Outdoor Gear are making extraordinarily light tents and tarps out of this stuff, yet the Sierra Designs and Mountain Hardwears of the world aren't using it. I understand it doesn't breathe well and thus condensation can be a problem, but is that a big deal? In other words, what are the arguments for not using it? Kevin Larkin Blacksburg, Virginia

I'm planning an Appalachian Trail through-hike for 2003. I've poured over all the gear columns/ratings/etc. And with a bit of your wisdom have narrowed down most of my gear.

I would like to buy a digital camera to bring on climbing, canoeing, and hiking trips. I had been planning to buy an SLR, but I've recently been tempted by digital cameras and their ability to make you impulsively take snapshots. What factors other then weight and picture quality should I consider? Any help you can give me would be much appreciated. Eric Winnipeg, Manitoba

To me, one of the great mysteries of life has to do with load ratings on boots. For exple, some day hiking boots are rated to carry up to 30 pounds after which, the boots will fail. Now, what the heck is the difference between a 180-pound person carrying no load versus a 150-pound person with a 30-pond load wearing the se pair of boots? Your enlightenment will be eternally appreciated. Jake Kim Irvine, California
