I'm trying to decide whether or not to shell out on a bunch of new equipment for a scuba diving course in Turkey this summer. What does the all-knowing Gear Guy say: buy all and be ready before I go, or rent equipment once I'm there? Grant Washington, D.C.

Can you wash waterproof gear? I was taught long ago that when I come home from a camping trip, I should wash and air out my tent and backpack, wash my sleeping bag, and wash the dust and grime off my boots (I usually wax them, too). That way the items would last longer. My boyfriend, on the other hand, thinks that washing things like waterproof gear, his bike trailer bag, or even his CelBak will "ruin" the waterproofing. As a result, his gear is smelly and dirty and I don't want to share it. Miriam Boise, Idaho

I have read that wool clothing is better than any synthetics made. Is that true? Smartwool is coming out with a 5.2-ounce lightweight shirt in August-could this be possibly the best shirt out there for backcountry travelers? Also, is there a pair of lightweight pants that perform well in a wide range of climates? I would prefer convertibles, but regular pants are okay as long as they breathe well. Peter Portola Valley, California

Here's a tough one for you: For personal reasons, I have recently switched over to the "organic" lifestyle. I trying to apply this to all aspects of my life, including my love of the outdoors. I an avid hiker, climber, and mountaineer and was wondering if there are any outdoor products (sleeping bags, tents, backpacks, boots, etc.) made from organic materials. Jeff Anchorage, Alaska

What are the pros and cons of jackets made with Ventile? Is this material worth the money? What about Nextec? Alex Strongsville, Ohio

Have you heard about the latest craze in the U.K.? It's called Paro clothing, and the claim is that you'll be throwing away all of your Gore-Tex outerwear when you start using it. What gives? A friend of mine who is a guide in Scotland lives by the stuff. Do you have any thoughts on the stuff? Is it all that it says it is? Arthur Long Valley, New Jersey

I interested in purchasing a multi-functioning watch, such as the Suunto Vector, something with an altimeter, barometer, and the like. I'd be using it when hiking, camping, or mountaineering; I'd even like to swim with it on. Is Suunto the only company that makes these watches? Is there a hiking watch that can do it all, even when it's freezing and underwater? Tony Detroit, Michigan

Is there anything wrong with using a regular detergent like Tide to wash fleece, instead of gear-specific products like Nikwax? Are there any other fabrics that shouldn't be washed with regular detergent? Joe Edison, New Jersey

I'm going to the Himalayas in March for a mountaineering course. I wear glasses and want to know what the best options are for eye protection. Prescription glacier glasses are a little expensive, and besides, I might need goggles at some point also, right? Apoorva Bethesda, Maryland

I have been looking for a paddling jacket in a waterproof-breathable fabric. It seems not so long ago that the choice was either Gore-Tex or Sympatex. Now it appears every manufacturer has its proprietary fabric (Xalt, WaveTex, H2NO, etc.) Are you aware of any side by side comparison of these fabrics available? Joe DuRant Newport, Virginia

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

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

I 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

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

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've recently started using the MSR Pocket Rocket, in place of my trusty Whisperlite, going through $25 worth of fuel in three weeks, compared to a gallon of white gas per season—a pricey switch, I'm sure you'll agree. Today I happened upon a Glowmaster fuel cartridge, almost half the cost of the Primus and MSR cartridges. Will it work as well as its more expensive cousins, and should I burn this instead of my greenbacks? Allen Tumwater, Washington

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

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

A friend and I are planning an attempt to summit Mount Shasta this summer. Neither of us owns an ice ax or crampons and we plan to rent those items when we get to the area. But recently I've been looking at Kahtoolas, which are kind of "crampons light." They're aluminum with no front points and touted as compatible with everything from hiking boots to running shoes. Looks like they might be adequate for a trek up Mount Shasta. Also, I might get some use out of these in future winter hikes. But they are north of 100 bucks (in the same territory as some entry-level crampons). Do you have any experience/insights on Kahtoolas? Mitch Thompson Shaker Heights, Ohio

Are there poles that could do double duty for downhill skiing and trekking? Or is that too much to ask from a set of poles for around $100? Dan Pittsburgh, Pennsylvania

My family of five—myself, wife, and three decent-sized kids—plus the dog would like to go snow camping, and I think I've got everything covered except the tent. As for cost, we'd prefer to be comfortable and broke over rich, frozen, and miserable. Unfortunately, I can't seem to find a suitable five-person tent—MSR's StormKing comes close, but only allows 12 square feet per person. I have concerns about splitting the family into two tents in potentially nasty weather. Do you have any advice? Nathaniel Nevada City, 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

Dear Gear Guy, can I extend the life of running shoes by using Dr. Scholl's gel insoles? Will they improve the comfort of hiking boots? By the way, I use orthotics. Gary Goins Denver, CO

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

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 looking into buying a soft-shell jacket and interested in the Cloudveil Serendipity, the Arc'teryx Gma, and another jacket from Salomon. What are your opinions on these jackets and are there any others that I should consider? Mike Kane Rock Island, Illinois

I was recently in New Zealand and purchased some Merino wool (Icebreaker brand) shirts and tights. They seem to have the se properties as polypro but are more windproof and don't smell after hard work. Can you purchase this azing stuff in the U.S.? What is your take on it? Nick Kelly Omaha, Nebraska

I have just purchased a new road-racing bicycle and now searching the market for some pedals. As you know, pedals are extras on most models, but what to buy: Time, Look, Shimano, Cpagnolo? The choice is a little overwhelming. Do you have any suggestions on some good, reliable pedals that will last and not cost a fortune? Weight's not an issue, nor is the latest, greatest technology. Wayne Luleå, Sweden

My son returned from a Scout backpacking trip on the Appalachian Trail just as we were loading the truck to move. In the midst of settling in the new home, we completely forgot about the tent and it sat in its dp stuff sack for weeks. What do we do with the tent now that it has mildewed? Is there any way to clean it without dage? Andy John Jacksonville, Florida

Since my boyfriend is useless regarding backpacking info and only cares to remember such things as hockey stats, I come to you for advice on a pair of Kayland 1700s that I want for extended backpacking in the Canadian Rockies. These boots come with Proof, a factory waterproofing similar to Gore-Tex. Do I need to apply an after-market treatment like Nikwax to the boots, or will that inhibit the ability of the lining to do its job? Jessica Alberta

I'm hiking the Chilkoot Trail next fall with two companions. What's the lightest three-person tent available? Mike Doherty North Vancouver, British Columbia

Which boot liner is better: leather or Gore-Tex? Personally, I've never had any Gore-Tex-lined shoes, but shop assistants keep raving about them. Some of my friends aren't so enthusiastic, though, complaining about getting sweaty feet on warm summer days. (I'm talking here about the "middle" category of mountain boots, like the Lowa Baffin.) Gerhard Innsbruck, Austria

Enlighten me, as I confused. We are planning a 12-month trip and I still looking for the "ideal" water filter. And I in doubt. Which to buy, the MSR Miniworks or the Katadyn Pocket Filter? Aside from the obvious differences (price, weight, flow rate, capacity), the carbon-core element of the MSR is the main difference. But why would I need a carbon-core element? Hans Janssen

What's the best two-person tent for under $300? Tom Ireland

Your Gearness, what boot do you think I would need for a four-month trek across the Indian Himalaya? I have a pair of Montrail Torre GTXs, but will these suffice? Tony Baltimore, Maryland

Can I use a standard tarp as a footprint instead of the manufacturer's footprint? Are there any significant differences between the two options? Ne Withheld Bangkok, Thailand

I'm so frustrated by how much boot sizes vary, even within the se model! I'm a woman, narrowing my options to begin with, and I'm a woman with narrow feet. I've tried several different La Sportiva and Salomon models, but still can't find the perfect fit. I don't have the option of trying boots on in stores as nobody around here has anything in women's sizes, so I've been mail ordering, to no avail. Can you help me? BJ Guilderland, New York

I've been considering getting a helmet for downhill skiing. Given the expense, I was wondering if it was possible to buy one helmet to cover several outdoor activities, in addition to skiing. I do a fair bit of skiing in the winter, but in other seasons I also go bicycling, do a little rock climbing, and may try inline skating this summer. I've rented them in the past, but would like to save the money on rentals -- as well as the expense of buying a helmet for every sport. Is there truly a helmet for all seasons? Some years back a similar question was asked, and the answer was "no," though the Petzl Meteor was mentioned. Wondering if this is still the case. Shawn Vitt Portland, Oregon

Recently, I bece aware of the cruel process of obtaining down feathers and I don't want to buy down products if I can help it. Please recommend a synthetic fill jacket that can keep me as warm as a regular down jacket does. Megan Singapore

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

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

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

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

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

Hopefully you can settle a debate regarding the use of climbing harness belay loops. When rappelling, a climbing guide said that the carabiner should be clipped through both the leg loop and waist belt where the rappel loop was threaded, not to the rappel loop itself. Others have told me that the 'biner should be clipped through the gear loop, not the leg loop and the waist belt. What's the correct answer? Tim Glastonbury, Connecticut

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

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

I starting to gear-up in preparation for climbs of Mount Baker and Mount Rainier this summer. I have an older Princeton Tec headlp that I use for backpacking, but can you recommend a good replacement? Are any of the newer LED headlps good enough to use when climbing? Kleet Renton, Washington

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

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

I'm taking a two-day bike tour with a friend. We are both concerned about the camping stuff we need to be carrying. Can you give some advice on what we should carry on our bikes? And which sleeping bags would you suggest? Ali Serefli Hartford, Connecticut

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'm wondering if you know the difference between all the soft-shell fabrics, specifically Power Shield and Schoeller Dryskin. Also, what's the deal with the ultralight rain shells like Patagonia's Microburst or Arc'Teryx's Sirrus SL? REI's Web site used to say that Sirrus SL is "truly an ultralight shell, thus should not be for everyday use." Are they suggesting the ultralight jackets are not that durable? Does it make sense to carry both a soft-shell and an ultralight rain shell on a long backpacking trip? Jenny San Diego, California

Is it 100 percent necessary to dry a tent in the sun after a few days of camping with heavy mildew? Miles Rowland Adelaide, South Australia

What are the differences between the gas combinations of various isobutane canisters sold by different companies (MSR, Snowpeak, Brunton, Gaz, Primus)? And how do they affect the performance of various stoves and lanterns? Garrett Tempe, Arizona

I moving to Switzerland for two years, and I want to buy a stove. I've heard that white gas cannot be found in Europe. Then again, if I buy a canister stove, how can I be sure I can buy the right type of canisters? I have considered getting the MSR Superfly because it's compatible with almost every type of canister. What's your take on my situation? Jay Springfield, Massachusetts

I'm looking for a raincoat that is lightweight and very packable, while also being waterproof and fairly breathable. I travel internationally a lot and need something that will look decent while in a major city yet also work while on the trail the next day. I'd like a jacket that doesn't have huge zipper covers or too many excessive components. I want something simple in a neutral or dark color so I don't stand out in foreign countries as much. Any suggestions for a durable, multi-functional, and ultra-packable raincoat that is lightweight and not terribly expensive? Jonathan Achter Minnetonka, Minnesota

Are Galibier boots still made? If so, where can you get them? No Name Given

Oh great and powerful gear wizard, I've gone and done it now. I have mildew—the brown spots AND the powdery green stuff—on my Bibler tent and Marmot sleeping bag. Please tell me I didn't just sink $1,500 worth of gear in the course of one monster rainstorm. Is there anything I can do? Julie Collinsville, Connecticut

It is better to have a full-suspension mountain bike or will a hard-tail with a suspension seat post be sufficient enough for a smoother ride? Paul G. Fort Wayne, Indiana

What's the best two-person tent for under $300? Tom Ireland

I recently purchased an Annapurna tent from Mountain Hardwear, because I'd like to start getting outdoors on more than day trips. However, the guy at the shop was reluctant to sell it to me, saying it was "junk" because it's a single-wall tent. What's the difference, and what are the advantages and disadvantages of this style tent? Lucas Denver, Colorado

Man, I confused! I want to purchase a synthetic-fill jacket for an upcoming canoe trip in Big Bend National Park. But it seems that all the major brands employ a different type of fill, running the gut from Polarguard HV and 3-D to Heatshield and Primaloft. So, Doug, I turn to you for expert guidance. Which is the best synthetic fill for warmth and compressibility? If there is not a "best", then what are the advantages of each? Finally, what jacket would you take? Steve Hurst, Texas

I'm so frustrated by how much boot sizes vary, even within the se model! I'm a woman, narrowing my options to begin with, and I'm a woman with a narrow foot. I've tried several different La Sportiva and Salomon models, but still can't find the perfect fit. I don't have the option of trying boots on in stores as nobody around here has anything in women's sizes, so I've been mail ordering. Can you help me? BJ Guilderland, New York

I bought a Canon Rebel 2000 kit in July to take with me to Alaska. I fully expected the picture to be crystal sharp—you know, the azure sky with white clouds and glacier and stuff. But after I came back and got them developed, I was very disappointed. Seems like the pictures are pretty grainy (like those taken using an APS camera), especially those sky/clouds and glacier ones. I used 200 speed Kodak Gold and the weather was sunny, but not too bright. What can I do to make the pictures turn out better when I go to AK again next year? Should I change the lens, the film, or the camera? If so, could you make some affordable suggestions? I'd rather not change the camera, unless of course, it'll give me great advantage. Oh, I got them developed at Ritz Camera, if that helps. Maybe their equipment just can't handle it. Please help me out here, I'm desperate! No Name Given

Because I sweat at a moderate activity level in cold temperatures, my insulation gets dp and looses it effectiveness. Layering and reducing exertion does not eliminate the problem. I a human fire hydrant. I have heard that vapor barriers could really help. Any suggestions on what to look for and brands? Ed Eugene, Oregon

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

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
