Can you recommend things to look for before purchasing a used bike? I interested in several Trek models and have found a couple of used bikes that appear in good shape. I would really love to save a few dollars by buying used and getting more bike for my buck. Carter Arlington, Virginia

Can you help me pick out the best-value sleeping pad? I'm new to backpacking and need my comfort while sleeping. Heck, I'd take my electric blanket along if I could. I want to find a pad that will be worth the money, but will last a long time too. I can't decide between a less expensive closed-cell pad and one of the inflatable ones. Are the inflatable kind that much better to justify the extra cost? Please help this confused backpacking novice! Kendra North Ogden, Utah

My wife and I will travel overland from Vietn to Turkey in 2003. We cannot decide what sleeping bags to take, as it will be very hot and wet in Vietn during the monsoon season, but cooler and dry when we are in Central Asia. Space, weight, and price are all issues. What do you think? Is there a light, extremely compact bag that will work when hiking in the jungle and also keep us warm in colder, alpine conditions? For the record, the tent we plan to use is a 1.3-pound mosquito net, with a fly and pegs if things get a bit windier. Andrew Darwin, Australia

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 best tent for winter camping? I'm interested in a two- to three-person tent that's lightweight, packable, and available at a low price. I will be spending time in northern Massachusetts and the White Mountains this winter. I've been looking into single-pole shelters like the Black Diond Betid ($98), and while comfortable with not having a sealed floor, I worry about water seeping in. Do these tarps really work? Are they reliable? Is it possible to find a reliable four-season tent under $200? Boaz Sender Boston, Massachusetts

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

In one of your long-ago columns, you gave the scoop on the well-known Cascade Designs Chair Kit and the Therm-a-Rest Chair Lounger. But in the spirit of "discovering" unknown, neglected products, does the Gear Guy have a take on the Sling-light chair (naturally, at slinglight.com)? Does this alternative, lightweight product deserve our consideration? Marshall Atlanta, Georgia

I have been searching for a backpack for extended trips, and it seems like all the local shops vacillate between Osprey and Dana Design packs. If you were going to buy a pack today, would you buy an Osprey Crescent or Dana Design Glacier? If so, why? Matt Albuquerque, New Mexico

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

All-knowing Gear Guru, I intrigued by Dana Gleason's concept of separating a backpack's suspension and pack into two separate components. Is this idea worthwhile? Also, Kelty is "the first licensee" of Gleason's Mystery Ranch System, and Kelty's line is significantly cheaper. Is there any difference? Dion San Francisco, California

Can you recommend a lightweight digital camera for backpacking? I was ready to purchase the Yashica T4 that you talk so highly of, but digital cameras are so compact and I don't need to carry all that film. Also do they make water-resistant digital cameras? Dan Hearty, Missouri

Do I need to replace my 1994 Oakley sunglasses? I wondering if the 100 percent UV protection in the lenses breaks down over the years with repeated exposure to the sun. If so, are glass and plastic lenses equally vulnerable? Joel Las Cruces, New Mexico

What's the difference between a bivy bag and a tent? Which would be a better investment (I'm thinking of room for two people here)? Noel Muscutt Louisville, Kentucky

I've recently signed up to do the San Francisco to Los Angeles Aids Lifecycle in May. I have done some mountain biking in my past (novice level) and taken spinning classes for years, but road biking is new to me. I decided to buy clipless pedals and tried out my shoes (Sidi) in a spinning class a few days ago. I was in pain—my calves crped to a point where I thought I would have to putate—and the outer side of my left foot was aching. What is going on? Are the shoes too small/narrow? How should I go about finding the right pair without wasting a ton of money? I really need advice. Joe Ashleigh San Francisco, California

I've read that good husbands buy gifts for their wives after the birth of a child. So, being a good husband, I'm thinking of getting a cyclocross bike—for me. Hear me out. Because of the recent arrival of our beautiful little miracle, I'm not going to mountain bike (that's one bike) or commute (that's another) as much as I used to, and probably won't be doing a whole lot of road riding (a third bike I was hoping to get), either. Plus, the missus would like me to pare down my belongings to make room for strollers and such. So, can I get by with one cross bike (sub $1,000)? I'm sure my wife will thank you. Michael Minneapolis, Minnesota

I would like your opinion on the Grigna 2800 trekking boots by an Italian company ned Armond. My main concern is the long-term quality of the boots since Armond is not a well-known brand and their boots cost about a third less than those made by more popular companies. I intend to trek to the top of Kilimanjaro this year. Ngoc Dung Phung Montreal, Quebec

What do you think of the new mohair socks on the market? Are they as warm as wool socks? Are they itchy?" Alexander Do Toronto, Ontario

Will salt water break down Gore-Tex and other waterproof-breathable fabrics? (I've heard tales of salt spray drying in the fabric and grinding away at it from the inside like tiny saws.) Is there a better choice in outerwear for kayaking and sailing on the Maine coast? Stephanie South Thomaston, Maine

I'm completely new to backpacking and worried about buying gear from just anywhere. Here in Canada, MEC (Mountain Equipment Co-op) supposedly carries nothing short of the best quality equipment and the thought of going to just one place for all your needs sound really nice. Would you, with all your experience, trust MEC for all your needs as much as everyone here seems to? Or do I have to shop around for everything separately, looking for reviews and such, and then spend tons of money in U.S. stores due to the crappy exchange rate? Your answer is greatly appreciated. Tatiana Calgary, Alberta

Is there a watch out there that is a dive watch and also an altimeter watch for skydiving? Ryan St. Petersburg, Florida

I enjoy weekend hiking and overseas travel. At the se time, I want to look good when I dress casually. Because of this, I spent $400 on a Patagonia XCR Gore-Tex jacket when Patagonia opened its first branch in Hong Kong last year. It's a very expensive outfit, but I do like it. However, after reading all your gear recommendations, it seems I could have bought something similar or even better. So, I'm now thinking of buying a fleece jacket for cold weather. Do you have any cheaper recommendations? June Hong Kong

Do you know where I can buy one of those Mountain Hardwear sleds? Who else makes sleds for hauling gear? Thom Salt Lake City, Utah

I'm going hiking on the West Coast Trail, and my boots have Vibr soles that are very slick on wood when it's wet. Since it constantly rains on the West Coast and I'll be traversing many wooden bridges and ladders, I was wondering if you could suggest a boot with a sole better suited to wet conditions. Dan Ottawa, Ontario

I work in the movies, and I need to find a good photo of a crevice ladder and then purchase one in Canada. Can you help me? The Props Guy Whitehorse, Yukon

Hey Gear God, Help me find the perfect scrambling boots! I love my old Asolo backpacking boots. They never needed breaking in, and after years of conforming to my feet, they're about as close as you can get to slippers and still be boots. Alas, they don't edge worth a darn. I need a 3/4- or full-shank boot that is made for wide, high-volume feet and is crampon compatible for alpine scrambling. I bought a pair of Solomon Super Mountain 9s online because they were a great price. Dumb move! They perform great and are the right length but they squeeze my feet like sausage casings. Is there a happy medium between my slipper Asolos and those sadistic Solomons? Julie Busse Seattle, Washington

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

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

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

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

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

What's the deal with waxed cotton raincoats manufactured by Barbour in England and Filson in Seattle? Although they don't breath well and would not work for high output activities, I have run into users who rave about their water repellency and durability, tempting me to buy one for around town and short hikes carrying minimal loads. Steve Albany, New York

While hiking I've noticed that many hikers are now using alcohol stoves. Is this a better way to travel? Also do you know where I could find instructions to make my own alcohol burning stove? Chris Smithsburg, Maryland

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 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

Despite the current trend towards light-and-fast hiking/backpacking gear, no manufacturer besides Eureka has looked at the rolled up size of even ultralight tents. They're still 5 feet by 18 feet or longer. Why not 6 feet by 12 feet? Or 6 feet by 10 feet? I've seen tents I'd really like to purchase but their packed size is too long to fit a small pack. Why is this? Ken Johnson Hollister, California

Where can I buy climbing/hiking knickers? I used to wear them in the '70s, but styles have unfortunately changed. Now I don't know of a single outfitter that carries them. Anything from European sources, perhaps? David West Monroe, New York

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'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

What types of materials in gaiters are best for snake protection? I know of Teflon, but is a heavy canvas also suitable? (If you're wondering how my question has any relation to where I'm from, it doesn't. I'm moving to Australia.)—Karen, Vancouver, British Columbia

Are there any high quality heated mittens on the market? My girlfriend suffers from Raynuad's and needs the warmest possible solution for skiing. You help is greatly appreciated! Chris Arlington, Massachusetts

Which is the best for weight-to-warmth ratio, fleece or down fill? And which midlayer out of the two should I pick and how should I dress if I to go to the coldest part of the world where it's, let's say -60-degrees Celsius? No Name Given

Is there a proper way to save your tent, short of taking it down, in winds over 50 mph? I had one fail, and I wonder if it was because I kept tightening the guylines, and maybe even over-tightened them. Joe Midland, Texas

I just read Outside's review of the new light technical shells coming out on the market and I realized that none of them are using W.L. Gore's PacLite material. A few years ago this stuff was the rage, but now I don't see any big ne manufacturers using it. Why is PacLite going off of the market? Is it a crummy material? Aaron Provo, Utah

Are their any compressible synthetic sleeping bags that won't leave you shivering and suffering? I mildly allergic to down, and I often carry a ton of work-related gear, so the space I have in my pack for a sleeping bag is limited. What are the best, most-compressible bags in the 15- and 0-degree ranges? Ben Higginboth Fort Leavenworth, Kansas

I'm moving in two weeks' time to a small island in Micronesia to teach for a year, and I've been told we will have no running water or electricity. Could you recommend an air mattress or cot that will last nine months and be pseudo-comfortable? How about reliable solar-rechargeable batteries? Or a sturdy water purifier/filter? Or anything else for that matter, as I'm at my wit's end! I will mail you coconuts and other treats from the Marshall Islands. Jourdan Mii, Florida

As the years go by, my wife and I find ourselves looking for lighter and lighter hiking and camping equipment, especially in terms of our shelter which takes up a significant portion of our pack weight. What's the word on Henry Shires' Tarptents? Their Squall weighs only 24.5 ounces and offers two people a roomy 44 square feet of space. Could this be the lightweight remedy to aching backs and our three-season shelter needs? V. Tran Galveston, Texas

My 2003 hiking season shall henceforth be known as the "Summer of the Bee," for all the stings I got. The long spell of dry weather was suggested to me as a reason, which I liked better than bad karma! Anyway, I quickly used up the three sting wipes in my first-aid kit and now own both REI's Sting Eze and After Bite. To my surprise, these two products use completely different active ingredients. Which one works best on stings? Chris Silverdale, Washington

I've finally decided to buy a GPS unit. My problem? I don't know which one. Your last review that I can find is three years old, but obviously a lot has changed since then. Rick Lebanon, Tennessee

Luckily, my company is relocating to a place where I'll be able to ride to work! What will I need to commute by bike three or four times weekly? I already have road and mountain bikes, plus the gear, but I don't think my racing garb will work for the daily commute. Loehr Athens, Georgia

I'm so confused by the different possibilities and terminology when it comes to rain jackets for biking. I bought a "waterproof" one, but it wasn't and I got soaked. I bought another and sweated so much that I wished I had the previous jacket. What's a good lightweight jacket for cycling that will keep me dry in moderate rainstorms? Mary Itasca, Illinois

What pants would keep me dry, breathe well, and shed plenty wind, all for under $100? I've had my eyes on Marmot's Precip pants, but what do you think about these? Are there other pants I should be looking at instead? On another tack, I assume you're a member of the Doug Club—oh no, have I given the ge away? Doug New York City

As a longtime reader of your column, you have helped me in the past. Now I need your advice again. I'm considering purchasing a canoe for family camping trips, something stable for small lakes and smooth rivers, nothing too extreme. What do you suggest in terms of size, length, and weight? Also, what type of carrying rack will I need for a shell-equipped Toyota pickup? John Springville, Utah

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

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

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

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

Do you have any tips, or can you recommend any sources of information, on how to remove tree sap from the outside of a Goretex XCR shell? Thanks!

O Most Knowledgeable One, what wind pants should I get: the L.L. Bean Guide Pants, made of Schoeller Dryskin, or the Marmot DriClime Stretch Pants? Your pearls of wisdom about the differences in performance are sought. Bill Charlottesville, Virginia

I was looking to buy a general, all-purpose, quality, hardwearing watch for travelling, hiking, work etc and was wondering if you could recommend one. I was looking at Suunto watches but unsure of their quality. Can you recommend a watch for me? Brendan Melbourne, Victoria, Australia

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 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

Not yet having gone digital, I have a standard 35mm camera with extra lenses, a detachable flash, and the requisite rolls of film and cleaning cloths. So, I'm looking for a backpack-style camera case with plenty separate compartments and padding. Ideally, it'll be sling-style, with small compartments on the front for ease in changing films, lenses, and so forth. I've already checked the local stores and a few large Internet sites, but they seem to make bags only for digital cameras now. Any suggestions? Sarah Tulsa, Oklahoma

For multi-day trips to the Sierras, I've been using an REI Wonderland external-fre pack, 5,000 cubic inches of cavernous, organized, old-school pack. Everybody I see these days, though, has internal-fre packs that look so comfortable (maybe they're fooling me). I still living in the '80s with my Wonderland? Is it time for an internal-fre pack? If so, any suggestions? Alex Chino Hills, 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

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

What's the best audio device that I can clip onto a pair of shorts when running and doing other multisport activities? Ceron Christchurch, New Zealand

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

Because of a small fire in our house I need to have three down sleeping bags, a jacket, and a vest cleaned. I need some suggestions of companies that will handle this operation and do it correctly. I may find other equipment and clothes as the clean up process progresses that need cleaning also. The smell smoke and soot of a house fire is not the se as that of a campfire! Gary Johnson Collegeville, Pennsylvania

What is meant by the minimum weight on tent specifications? S Weatherley Birmingh, United Kingdom

I plan to buy a bike for my wife, a long-overdue birthday present, to be used mostly on backcountry roads (gravel, dirt, or tarmac) but not on trails. I'm looking for something that is good quality and will be comfortable for a 30-mile ride. A racing bike seems too fragile, while the ubiquitous mountain bike seems like overkill. Is a hybrid (whatever that is!) the way to go? I really require your guidance, as this gift is somewhat late. Steven Westmount, Quebec

I have logged many air miles with my MSR Whisperlite AND empty fuel bottles. I have never been given any problems (including post 9-11 from New York area airports) having them packed in my luggage. I do, however, take a couple of precautions. These include calling the airline before hand and getting the name and customer service ID of the person I talked to, keeping the fuel bottle clean and uncapped (leave some soap residue inside so it will smell clean), and always checking in at the counter so you can tell the attendant that that the thing that looks like a bomb is a stove and bottles. Most of the time the attendant checks the equipment and that is all (sometimes they mark my luggage with a weird tag). I have on other occasions had an attendant repackage the stove in the airline's special box. I feel that if you are up front about it and take a little care, things will go smoother. However be prepared for the guy who is a hard nose as you may still lose your stove. Jonathan Cushing New York, New York

I'm in the market for a decent down jacket but don't want to fork over the money for a Feathered Friends Rock & Ice Parka, as good as it is. What do you know about the Frobisher 700 Parka from Mountain Equipment Co-Op (a Canadian company)? It's stuffed with about 16.5 ounces of 700-fill down, has a Dryloft shell, and sells for about $285. It seems like deal to me! But I'm curious how it stacks up against Mountain Hardwear's Sub Zero SL Parka. Any help would be greatly appreciated. Michael Gebhardt Chattanooga, Tennessee

Gear Guru: I work out almost every day, so I need a lot of base-layer garments. When it's not too cold out, my CoolMax Alta turtlenecks seem a good deal. But what about the other, pricier options? Do these have wondrous additional capabilities worth the extra cash? David Portland, Oregon

Raichle's Mountain Trekker backpacking boot is the best boot I have ever owned, and I would like to purchase another pair. However, I can't find anyone that carries them anymore. Could you help me out with information on where I could get a pair? Trevor Calgary, Alberta

I read the article about the Crawford Survival Staff in the 2000 Buyer's Guide, but I wanted to ask if it's really worth the $225. You're the only source of reliable information I have! Did you actually field-test the staff? Alex
