I'm really getting into ultralight backpacking, and I hope to do a through-hike of the AT or PCT in the next few years. I do all of my backpacking in the summer, but my Marmot sleeping bag is too heavy (and warm). What choices are there for a light, compressible bag costing less than $100? If there are no bags in this range, would you recommend removing some of the down from my Marmot bag to make it lighter? Tom Bellevue, Washington

Why don't sleeping bag manufacturers make the outer shells on their bags from the se materials used in waterproof-breathable jackets? Thanks for your time and answer. Steve Youngsville, Louisiana

My wife and I like to share a cozy sleeping bag while kayak camping, but we both own "pre-marriage" bags that don't zip together. What we want is one bag wide enough for two, made from synthetic material (since it might get wet), and with a temperature rating of about 20 degrees. Also, as we're both about five-foot-five, it would need to be on the short side. Is our only choice to have a bag custom-made? Andy Kirkland, Washington

I'm looking for a boot that is automatic crampon compatible. Also, I'd like it to be a very well rounded boot—I need it to be able to go on extended backpacking trips and even some vertical ice climbing. What is my best choice? Dan Charlton, Massachusetts

What's your take on the soft-shell craze if the activities are both ascent and descent in nature? In other words, I very interested in the breathability for aerobic activities, but concerned about warmth for activities like downhill skiing. Question is, can I have my cake and eat it too? Second, if I can have it both ways, what is your first choice and why? Brad Peacock Medina, Ohio

I looking for a cold weather running jacket that is extremely breathable and wind-resistant (waterproofness is not a necessity). I've been using Lowe Alpine's Adrenaline jacket, which is great for hiking but stes up quickly when I running hard. I usually buy The North Face and Patagonia products but I not sure that they make the best stuff for running. What do you think? Nick Kogevinas Washington, D.C.

What's the best backpack for scrambling? I have taken to canyoneering, usually carrying trekking poles for balance, two ropes, other climbing gear, and occasionally a wetsuit. I'd like to know if there's a slim, lightweight, 3,000- to 3,500-cubic-inch pack that will hold the poles, a water bladder, and my climbing equipment without making it look like I'm tackling Everest. Ray Chicago, Illinois

"I just got through watching reruns of the Eco-Challenge, and was wondering what those competitors (and us less adventurous hikers) can do for very wet, muddy, and slushy hiking conditions? How about Gore-Tex socks and some strips of duct tape around each calf to keep the water out?"

What type of shoes should I wear for day hiking in the Costa Rican rainforest—sandals, trail runners, or water shoes? I will be going in November, historically one of the wettest months of the year. Dion San Francisco, California

Do water bladders sweat inside a daypack? My daypack is big enough to hold a bladder, but I'm worried my other stuff will get soggy if I pack next to a bladder. I worrying for nothing? No Name Given

Have I got an expensive proposition! I'm planning a trip to Italy and thinking it might be the perfect time to buy a new road bike straight from the factory, say Pinarello, De Rosa, or Colnago. Are there any advantages to doing this, such as incredible savings, or seeing the bike in progress and test riding it in the mountains? Are there drawbacks, such as duties, taxes, exchange rates, warranties and language that would make this way more trouble than it's worth? Thanks for your wisdom! Bob Foster St. Louis, Missouri

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

Last summer, I bought a Shan light touring kayak from Wilderness Systems (based largely on your recommendation, O Great and Wise One). After some great day trips, I'm now planning a multi-night river trip, so I'm looking for some packing advice. The boat has a rear bulkhead and an air bag up front for flotation. Should I pack my gear at the back with extra stuff lashed atop the stern, or can I replace the front flotation bag with a tapered dry bag? Zippo Baltimore, Maryland

I'm looking for a good underwater and above-water digital camera. Any suggestions for what I should look for? Margaret Hilo, Hawaii

Are there any materials that can offer reasonable rain protection and still breathe well? I can't use Gore-Tex in anything but the coldest conditions without getting significantly dp. How does REI's Elements line stack up? Ken Johnson Hollister, California

I'm going hiking on the West Coast Trail and I have boots with Vibr soles. They are very slick on wood in wet weather. Since it constantly rains on the West Coast and you have to traverse many wooden bridges, ladders etc., I was wondering if you could suggest a boot with a more water-friendly sole. Dan Anstey Ottawa, Ontario

What is the stiffest material that a road-racing bike can be made of? Also, what's a good compromise between a really stiff bike and a really light bike? Justin Seattle, Washington

Oh Gear God, I've eschewed "wind-blocking" fleece over the years in the belief that something like Marmot's Driclime Windshirt is more efficient. But then I went to Patagonia and discovered their oh-so-tempting R4 jacket. Of course, having disdained wind-blocking fleece for so long, I know nothing of the advantages and disadvantages of Gore Windstopper, Polartec Windbloc, and Windbloc-ACT. Can you enlighten me? And, while you're at it, do you think the ever-so pricey Patagonia version is worth the extra dough? Finally, is it gilding the lily to put a windbreaker over one of these wind-blocking whatchacallits to keep them dry in a light rain? Mark San Francisco, California

Tent versus tarp? Scott Gillette San Jose, California

My wife and I are looking for a canoe, to use mainly during weeklong trips on flattish water: something sturdy enough for rocks and beaver ds, yet light enough for long portages; large enough to carry our packs, yet small enough to be nimble in narrow creeks; stable in wavy conditions without feeling as though we're paddling a tugboat. Can you help us navigate these compromises and suggest some good all-round tripping canoes? Rob Calgary, Alberta

Can you recommend some easy ways to reduce condensation inside a tent? In what sort of conditions should I expect the most condensation? Carter Virginia

OK, call me a masochist, but I love winter camping. However, when I try to convince some members of my family to go with me, the answer is always the same: "Too cold." So I spy the Zodi Hot Vent II ($135), which uses a propane cylinder to provide heat to the tent. This could be just the ticket! But does it work, and is it safe? Only the great Gear Guru knows for sure. Jeff Minneapolis, Minnesota

Up until now, I've been content with either picking a wilderness that allows backcountry campfires for cooking dinner, or eating cold food for the duration. Now I'm starting to feel like my choices are limited and/or my dinner sucks. What kind of backcountry stove should I be looking into, and what is the difference between the different fuels? For the stove, my most important prerequisites are that it's lightweight and reliable. Mark Brick, New Jersey

What's the advantage of wearing mountain bike-style shoes with pedal clips, versus regular, all terrain-type shoes? Also, how does one escape from the clip? Jes Greene, New York

My wife's extremities get very cold on winter backpacking and ice climbing trips. I'd like to get something to help her out. I was looking specifically at the Moonstone Sauvage Glove. Any other recommendations? Chris Ralph Mountain View, California

Oh Great Gear Guru, I have a simple question. I recently ce across "directional clothing" by a manufacturer called Paro. Have you heard of it, and more to the point, have you had the opportunity to try it out and rate it? I would like your opinion on this stuff. Andrew London, England

During the winter I run in the early morning hours when it's dark and cold. What do you recommend for a good reflective winter running outfit? Lance Delafield, Wisconsin

We recently acquired a German shorthaired pointer who loves to swim in the ocean—not just play around in the surf, but really get out there and swim past the waves. Trouble is that with her short hair, she is freezing cold before she's tired out. We'd like to purchase a "doggie wetsuit," so to speak. Since we live in the self-proclaimed surf capital of the world, it seems a logical idea. Should we purchase one of those hunting-dog neoprene vests? Or are we just acting like overly-protective, wussy Californian dog owners? Thanks for not laughing too hard. Deb Encinitas, California

My husband and I are neophyte campers who need a tent that is reasonably priced, waterproof (Florida's thunderstorms are sudden and legendary), roomy, well ventilated (humidity here reaches 99 percent most of the year), and useful for both forest and beachside camping. Did I mention that we have only $150 to spend? Lynn Orlando, Florida

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

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

My 1994 old-school Nishiki Backroads has no suspension and I'm starting to weekend-warrior on single-track off-road. Should I upgrade components on the existing fre, or go new with a hardtail or dual-suspension bike? My budget is less than $1,000. Marc Richardson Oakland, California

Could you please tell me what you figure the efficiency of slicks versus knobby biking tires is? A local dealer says it is insignificant, and I figure it is ten to 15 percent. Bill Invermere, British Columbia

I in urgent need of a warm sleeping bag for use on an upcoming desert running race I entered in, the Marathon des Sables in Morocco. Although this conjures up visions of heat and sleeping under wispy silk fabric whilst warm winds blow, the reality is that at night, temperatures can plummet to freezing. I'm not too concerned about cost and need a bag which is at least good for about 32 degrees, and most importantly, LIGHT!! It has to be carried and raced with for over seven days. Please recommend waterproof varieties or appropriate techniques as it can pour. Dio Wong Hong Kong, China

My summer bag is an Integral Designs Andromeda Strain (40-degree, Primaloft); my three-season sack is the North Face Cat's Meow (20-degree, Polarguard Delta). Both are sweet bags. My question: can these bags be combined (summer bag inside three-season bag) to make a winter bag? Will I gain much, or will the inside bag be unable to loft up and therefore not provide much additional benefit? Thanks! Bill Stell Charlottesville, Virginia

I was thinking about combining my expandable Mountain Hardwear Galaxy SL sleeping bag with the maker's 40-degree Down Upgrade bag. What do you think about combining these two sleeping bags for a Denali summit attempt? Rob Boston, Massachusetts

As a bowman on a racing sailboat crew, I called upon to climb various things. The usual practice is to wear a climbing harness rather than use a bosun's chair as it saves time on the racecourse. My problem is that salt water is corrosive, and our usual sailing area off the south coast of the U.K. is particularly so. I'm not too comfortable going up the mast wearing a harness where the buckles are showing signs of corrosion. Is there a harness with buckles made of stainless steel? Or what other solution could you suggest? Edward London, England

I would like to buy shaped skis. I currently ski on straight 160s and 5-foot, 2-inches tall. I've gotten so many different opinions on how long my shaped skis should be. Help! Jacklyn Meriden, Connecticut

I need something to go over snow terrain in the most efficient way possible for a winter approach/ascent of Split Mountain in the Sierras. Instead of clunky snowshoes, what do you think about the Yupi Skishoes? Or the Salomon Meta Skis? Between the two for rough, snowy terrain, which would you recommend? By the way, I'm a VERY novice skier, so something easy to learn is important. Jake Kim Irvine, California

I having a very tough time finding hiking boots that are comfortable; they all seem to hurt somewhere. I did find a pair of comfortable trail runners, and I'm wondering if I'd have any trouble day hiking in Glacier National Park using these instead of hiking boots or shoes? How much of a difference is there? Laura Jefferson City, Missouri

I looking for a boot that can do just about everything, including hiking, backpacking, mountaineering, as well as a little bit of climbing and bouldering. I would also prefer a crampon-compatible boot that can handle the snow and cold. Any suggestions, besides going out and buying five different pairs of boots? Jeff Midland, Michigan

While preparing for a recent overnight backpacking trip in the Adirondacks, I was surprised at the weight of my loaded pack. Despite having modern "lightweight" gear such as a Western Mountaineering down sleeping bag and the Sierra Designs Clip Flashlight CD, my pack probably weighed 50 pounds. The pack itself, an Arc'Teryx Bora 80, is somewhat heavy, but I needed its size to fit all my gear, including a bear food canister. Do you have any advice for reducing the weight of my pack for an overnight trip?

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

I'm planning a three- to seven-day mountain biking trip this summer. If I'll be riding up to six hours per day, what tent, sleeping bag, and backpack will I need? As always, your advice is very welcome. Mark New York City

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 interested in buying a new kayak for touring and open-water paddling, but one that could also take a little whitewater action once in a while. What would you recommend? Jeff Midland, Michigan

I have been looking for a three-season alternative to my mountain tent, which has proven bulletproof for backpacking and climbing expeditions in mild conditions. The North Face Tadpole 23 seems to be a lightweight, good-looking choice, and since it's from The North Face, I have no questions on quality. What do you think? Christian San Diego, California

I bought a pair of leather Scarpa hiking boots, but I'm having trouble breaking them in. The soles feel too rigid and it hurts to wear them, even for a short hike. I think they are too sturdy for my weight of 116 pounds. Some people have told me to get them wet and then hike in them. What do you suggest? Janet Payson, Arizona

You have mentioned in the past that you are lukewarm on single-wall tents as in some circumstances they are neither as warm (winter) or as cool (summer) as double-wall tents, and prone to condensation issues. But you have also recommended the single-wall Bibler Ahwahnee, especially when weight is an important factor. I'm also curious if single-wall tents make a similar two-way compromise to that of modern membrane clothing—neither letting perspiration out perfectly nor keeping very heavy rain out perfectly. You have mentioned half of the clothing equation as an issue with single-wall tents. What about the second half—do they also leak in very heavy rain? Stephen Piper Alexandria, Virginia

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

Any recommendations for a two-person backpacking tent big enough for a six-foot, five-inch, 250-pound camper? I already have a Sierra Designs Clip Flashlight two and it seems a bit small for just one person (me), especially after more than two nights of foul weather. Jim McGowan Charlotte, North Carolina

I'm planning on hiking Vermont's LT, and because of past knee problems I'm trying to pack as light as possible. I've been considering buying the Mountain Hardwear Phantom sleeping bag, but I'm concerned about its down fill. Any thoughts? How effective is the water-resistant coating used on the superlight bags? Neil Westport, Connecticut

I am looking for a tent that will repel dew, especially as I hate the damp feeling that comes from wet grass. Which tent do you recommend? I don't do much camping, but I do like to be comfortable when I do. Tara Bowler, Wisconsin

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'm a snowshoer and snowboarder. I wear hard-shell snowboarding boots and I have the step-in type bindings on my board. I would love to find some snowshoes that also have a step-in type binding that would work with my boarding boots so that I could do some backcountry boarding and only need to haul one pair of boots. Any suggestions? Ryan J. Richmond Boise, Idaho

Gear Guy, dress me for kayaking in the marshes of the lower Connecticut River this winter. It's prime roosting territory for Bald Eagles through late February. David Hadd, Connecticut

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

OK, this is a serious question. You seem like the kind of guy who does a fair amount of biking in cold, windy places. I've recently started to use my bike to commute to work and have noticed a "small" change in a very personal area. The wind goes right through my pants, and when I arrive at my location my little guy is tucked away like a scared turtle. This isn't a real huge problem, just inconvenient and uncomfortable. Do you know of any underwear or pants that could help fight this problem? Karl Rostock, Germany

I looking for a two-way radio. I don't know much about them and need some advice on a dependable and weatherproof model for outdoor activities such as camping and boating. So it would need to be. I hear you need a license for anything that has range of over five miles and would like to avoid that. KJ San Diego, California

This past summer I started running and now have continued into the winter. On the longer runs my privates get awful cold. Is there any underwear out there made of microfleece and/or windproof fabric? I run in tights and wear cotton briefs under them. The cotton is the problem. I don't like wind pants or wearing shorts over my tights, but are they the only answer? Tom Faherty Scituate, Massachusetts
