I enjoy everything about my new digital camera except for the short battery life, which is especially annoying when on multi-day hikes when the battery might suddenly go dead. Are there any solar-powered products out there for recharging batteries while on the trail? John Swanton, Maryland

Oh Being of All Gear Wisdom, Following your sage advice, I've been looking for a Yashica T4 point-and-shoot to replace my partner's camera, which bit the Grand Canyon's dust on our last trip there. It appears that Yashica no longer makes the T4. Nor do they seem to have a successor model. What's your current recommendation for either a fixed or zoom lens 35mm P&S? Being a photographic troglodyte, no digital cameras allowed. Rob Brading Fairview, Oregon

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

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

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

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

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

Is there a liquid-fuel stove that gives out good heat, but that is also quiet and compact? The MSR Dragonfly is fine heat wise, but it's incredibly loud. The Optimus 111C is hot and quiet, but it's too bulky. Bruce Oakville, Ontario

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

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

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

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

My ne is George, and I a Gearaholic. I know I have a problem, but I cannot control myself. Although I have eight packs, ranging from a Gregory Denali Pro to a Mountainsmith Ghost, I have the se dilemma with all of them. Though of average build, my hips are non-existent, causing my hipbelts to slide down my waist. This problem can be very bad in winter when lugging a heavy pack and wearing slippery Gore-Tex clothes. Are there any gripping solutions that can be applied, or is there another pack that can cure my problem? George Rochester, New York

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

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

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

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

I live near North Carolina's Outer Banks and want to purchase a kayak for island hopping. What boat would you recommend for a beginner paddler? Jie Beaufort, North Carolina

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

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

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

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

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

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

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

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

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

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

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

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

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

Can you help me choose a boot for a trip to Argentina's Mount Aconcagua? I have summited several fourteeners in my La Sportiva Makalus without a hiccup, but I'm afraid Aconcagua is too much mountain for these boots. We plan on tackling the Polish Glacier route, and I was leaning towards a plastic double boot like Koflach or Scarpa. But, as usual, your input could sway me! Eric Palmetto, Georgia

I know nylon fabrics deteriorate from too much exposure to the sun, but does nylon lose its strength from old age? Is a sleeping bag that has been in storage for 20 years without seeing one ray of sunshine still "as good as new"? Are there both "good" and "bad" quality nylon fabrics, or are they all made equal? David Sparta, Michigan

OK, so jogging on the trail with a baby isn't safe. But, I would like to go backpacking after our baby is born. Are there any all-terrain strollers suitable for trails? I know there are baby carriers to wear, but dad still has to carry the rest of the gear, doesn't he? M. Dittman Cleveland, Tennessee

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

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

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

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

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

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

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

I bought a Marmot Massif XL sleeping bag because I'm somewhat claustrophobic and wanted a high-quality down bag with ple room. While it indeed has plenty of room, the extra space makes it far less heat efficient—it's rated at ten degrees and I'm barely warm enough at 25 degrees. What kind of liner would you recommend to add warmth for colder nights but not defeat the purpose of getting a larger bag? Neal Pratt Portland, Maine

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