DATE NIGHT, UPGRADED The problem: You and your significant other share a love for camping, but your zipped-together sleeping bags and mismatched pad combo are causing a divide. The solution: The King Solomon. When its internal pad sleeves are stuffed with two 20-inch-wide mats, the King’s system works beautifully—there’s no…

BEST FOR HOT WEATHER Beat sweaty-back syndrome with the Z 55's ventilated suspension. The frame's concave shape creates a pocket of cooling air between your back and the pack. Most impressive: There's zero drop-off in load support. The perforated framesheet efficiently transfers weight to a perfectly sculpted hipbelt, and a…

Tiny and versatile: Simply slide the featherweight, CR2-lithium-powered headlamp’s toggle to strap it to anything, be it your cranium, messenger bag, or handlebars. 1.4 oz; coleman.com…

VERSATILE THREE-SEASON SACK The EcoPro costs a bit more than Marmot’s other synthetic 15-degree-rated models (like the Trestles 15, $90). But this bag has good karma. Its insulation and shell are spun almost entirely out of recycled plastic bottles. In fact, the only unrecycled things on this roomy bag are…

For such a light and warm bag, the 800-fill Peggy is packed with such thoughtful features as a built-in pillowcase. Like all of Big Agnes’s bags, there’s no insulation on the underside, but it’s compatible with any 20-inch-wide sleeping pad. 15°, 2.5 lbs; bigagnes.com…

EMS’s 20-degree Boreal is the first sack to use a new synthetic insulation from Prima­Loft called Infinity, which EMS claims is “18 percent warmer and 25 percent more compressible” than comparable fill. Although it was impossible to test that boast, the Boreal squashes down to the size of a…

Thrashers Welcome The 725-fill Tumble Mountain features recycled fabric, zipper, drawcords, and cordlocks, making it the most sustainable bag here. It’s also the most tricked out. Big Agnes shaves a few ounces by eliminating the unnecessary insulation under the half-length pad sleeve on the back. Slide any standard-width (20-inch) pad…

New-School Lantern Your old propane-powered lantern might have sentimental value. But it’s also fragile and high-maintenance. That’s why we like the Titan. It runs on four D batteries, is bright enough to illuminate an entire cooking area (45 feet in diameter), and has a power meter to let you know…

Not that you’d need it, with SIERRA DESIGNS’ BTU -5 SLEEPING BAG—an 800-fill down heat factory with one of the best heat-sealing hoods we’ve ever tested and a waterproof-breathable fabric.

Why It’s CoolThe freestanding Sage didn’t budge during 80-mile-per-hour gusts—its aerodynamic three-pole architecture lies low. » You can’t go wrong with the unique color-coded strap-and-buckle design that accepts the pole ends in tidy slots. » Two see-through windows are great for starry nights. Mesh canopy panels, a mesh D door,…

Why It’s CoolThis one-pound-three-ounce bag has no hardware—no zip, no Velcro—just a single cinch clasp on the hood’s drawcord. » The Beeline is rated to 30 degrees, thanks in large part to the 900-fill goose down’s impressive loft. » Shaving additional grams is the Pertex Quantum fabric used in the…

Why It’s CoolThe Eagle has landed! This one bears a retro-chic likeness to the 1969 Apollo landing craft, down to the folding footpads. » Dock fuel line to fuel bottle with a gratifying click, commence pumping, and—presto—the Apex II is chugging away with a whof-whof—and no need to prime it…

This freestanding dome is only a few tent stakes over three pounds, yet it skimps on almost nothing. With a design that eliminates wasted corner space—hence wasted weight—the Evolution has two doors, two vestibules, a legit two-person floor, and a comfy 42 inches of headroom. Double-wall construction, with a…

The bright, travel-friendly Icon runs on either alkaline batteries or an optional rechargeable battery (called the NRG; $30) that comes with four different outlet adapters. 6.6 oz; bdel.com…

WARM IN ANY WEATHER OK, sometimes sleeping outside just plain sucks—like when it’s cold and wet and you’re without a tent. Fortunately, the Cirque is made for just such nights. On a soggy ski-touring trip in Mount Baker–Snoqualmie National Forest, testers spent two nights en plein air in the 800-fill-down…

OVERACHIEVER This streamlined pack performed above its weight class on every trip, thanks to durable polyurethane-coated nylon throughout and a suspension—framesheet and aluminum stay—that can handle a heavy load. One tester took a larger version (called the Quest, 4,250 cu in, $175) on a weeklong trek in Wyoming's Wind River…

It’s like putting your car’s high beam on your head. Powered by a 1.4-pound rechargeable battery pack, this Swedish-made, 20-watt halogen lamp is ridiculously bright and per-fect for caving or mountain-biking at night. 1.8 lbs; milausa.com…

EXPEDITION-READY Kelty developed the new Foraker line in conjunction with Alaska Mountain Guides, an adventure outfitter whose guides spend hundreds of days in the field. You can tell: This 750-fill sack is the toughest, most packable sleeping bag Kelty has ever made. It’s cut from three different fabrics. A water-resistant,…

If we had a Most Comfy award, this recycled-synthetic Climashield bag would win. Credit the recycled Cocona liner—which wicks moisture and feels more like sheets than slick nylon—and the cozily lined foot area. The trade-offs: It’s not as compressible as other synthetics, and it’s a tad heavy. 5°, 3.4…

As with previous Kazoos, this 15-degree bag is still stuffed primarily with 600-fill down and bedecked with smart features—glow-in-the-dark zipper pulls, easy-to-adjust hood, etc. Even more impressive, this Kazoo’s shell and insulation are made with 100 percent recycled materials. Plus, it’s a hybrid. There are compression-resistant, synthetic insulation pads…

Best for Cold, Wet Weather This is a great price for any zero-degree-rated bag, never mind one stuffed with PrimaLoft Infinity, a top-shelf but affordable synthetic insulation with a great loft-to-compressibility ratio. Just don’t expect the same fabrics and tailoring as on high-end bags. There’s no ergonomic footbox, and the…

Rainbow Bright The Multi Color’s main LED has three light-level settings and four smaller, colored bulbs (two red, two blue) that are more useful than you’d think. Their muted glow preserves your night vision, whether you’re up late stargazing or tying on a predawn fly. 4 oz;…

Now, shelter. The steep walls of BLACK DIAMOND‘s ultralight (2.8-pound), single-wall HILIGHT TENT shed snow, and it packs down small enough to save space for booties. Or build an igloo.

Is it safe to use one of those Brita pitchers to filter river and lake water while camping? -Eric Oakland, CA

Can you recommend any method to protect zippers from salt water corrosion? We camp three to four times a year on the beach and I have noticed that the zippers are beginning to show signs of deterioration. Can I do anything to help preserve the zippers? -Alex San Juan, Puerto Rico

My son is a Boy Scout and had a very nice and somewhat expensive cold-weather sleeping bag from The North Face. He recently discovered a small tear in the nylon fabric. I am looking for advice about how to patch it. Can you give some advice to a Loyal Scout Mom?

I have an older tent, it's still in great condition... except it leaks. I was in a rainstorm and the whole tent leaked, not just the seams but the actual roof fabric. After the tent dried I sprayed sealer I found at the local department store and let it cure, but the next rain it did the same thing. Can you recommend a great spray sealer and seam sealer? Or am I wasting my time and need another tent? The tent is a large two-room tent with an enclosed screen area in the front and we love it, just want to try to save it. — Ramon Elgin, IL

I was just reading about pepper spray repelling a mountain lion...what about using one of those very loud boating/marine fog horns? These horns are quite small but can be very loud.

Years ago I wrote in and you recommended a Gregory Forester pack for my separated shoulder. It has served me well. I have lost too much weight for the large belt to keep the pack on my hips and getting a new belt has been difficult. I am headed to Philmont and am looking at the Gregory Baltoro 70, Osprey Aether 70, Deuter Act lite 60 +10, and the REI Flash 65. Could I go wrong with the REI Flash? Very light on the back and wallet. Mike Spory, VA

I'm graduating from a Masters program in May, and planning, possibly, my last great summer get-away before becoming a hard-working stiff in September. My itinerary from mid-May through August includes a hiking/camping cross-country road trip to Sedona, two weeks of camping and hiking in Alaska, volunteering as a fly-fishing instructor in Alaska, and traveling in Asia for three weeks. If you were putting together a recommended gear list (particularly lightweight waterproof jacket, backpack, tent, and sleeping bag) from scratch where would you start?—JosephPittsburgh, PA

In the last few years I have really taken to trail running long distances. My long runs can last over eight hours and are often big loops or out-and-backs in the mountains. Stream water is abundant on the trails in Cascades where I run but unsafe to drink untreated. When I hike or backpack I can take my water purifier. While trail running I try and travel light. It looks like some of the treatment tablets take up to four hours and are not effective against all the nasties in the water. What do recommend for water treatment?—TomSeattle, WA

I am trying to decide between a Gregory Whitney 95 or the Gregory Baltoro 70 for the best-all around pack for anything from weekend trips to taking on the Appalachian Trail, and hopefully further reaches of the planet. Just trying to decide if the Baltoro offers enough space for the AT or if stick with the Whitney.—DavidOcala, FL

What's the right choice for a two- or three-person tent with a good balance of lightweight ventilation and privacy?—AllanSaraland, AL

I am looking for a portable, bright lantern that would do admirable service for hut-to-hut ski trips or sea-kayaking excursions. Is there one available that runs on liquid fuel? This would permit a modicum of fuel economy as I am still using my SVEA 123 stove, and avoid using throw-away canisters (recyclable though they may be). My Coleman 222 lantern just heaved its last gasp on a recent winter trip to the Gaspe and, sadly, needs to be replaced.—GeofferyToronto, Ontario

Hey, I'm looking for your recommendation on high-quality lightweight tents. I lead extended backpacking trips (30 to 45 days) in Alaska during the summer (read: snow is likely, so both three- and four- season tents are options), and am hoping to find a good three- to four-person tent that can withstand strong winds, heavy rain, and is light enough to be carried by the group. Double wall is preferable. Any suggestions? I'd like to keep the price under $600 if possible.—CaseyO'Malley, NY

I have a Bibler Ahwahnee, which is a brilliant tent, but I see new options for tents that are a kilo or more lighter. Having compared Black Diamond’s HiLight and Nemo's Nano, they look sturdy and light. But how can I check for breathability to match my Bibler?—IanJohannesburg, South Africa

I travel a good deal, mostly to visit friends or on vacations. I've made it my goal to never check a bag, which of course dictates that I pack simply (and wash clothes often). It also demands the right bag for the job. What would you recommend?—DavidDansville, NY

Do emergency blankets make a good alternative for a sleeping bag, in terms of ultra-light backpacking? Would they be good for repetitive use? Steve Edmonton, Alberta

I?m looking to invest in a sleeping bag and want to know how to choose the proper temperature rating. You?ve said that it must be rated ten degrees warmer than the coldest temperatures expected. Why is that? And is that in degrees Celsius? Also, I will be purchasing a tent, so how much do I rely on the tent and how much on the sleeping bag? Is the tent only for the wind and rain, or can it be really warmer? Vladimir Tokyo, Japan

In your experienced opinion, who makes the best three-season, solo, CONDENSATION-FREE, tent? Michael Santa Fe, NM

With the approaching winter solstice, my evening outdoor runs require illumination. This activity takes place in an unlit park laced with footpaths that can be hazardous to aging ankles. My headlp, though fine for cp chores and reading, just doesn't provide enough light, particularly when moving at speed. Can you suggest a lightweight personal torch that would do the trick? I not as concerned with burn time as I might be if I’m on a wilderness excursion. Diana Westmount, Quebec

I'm looking for the lightest breatheable bivy sack out there, any suggestions? Gabe Lander, WY

How do you evenly redistribute the down in a sleeping bag? I was cold while backpacking recently and noticed that the down was not well distributed. It was clumped in some areas and bare in others. Sherry Parker, CO

What is the lightest two-person three-season tent? I define a tent as something that is big enough to lie down or sit in, and keeps the rain and bugs out. All the manufacturers are trying to confuse me by listing minimum weight, packaged weight, trail weight, fastpack weight, packed weight... Erik Rochester, NY

Hi, I want to purchase a water filter or water purifier to turn my day hikes into some overnight trips. I have been doing a lot of research but can't seem to figure out which one I need. I'll primarily be hiking in the Northeast and only in North erica, so is there a need for an actual water "purifier"? Thanks in advance. Kane Red Bank, NJ

For hiking in the Andes, what four-season tent would you recommend? Looking for one that'll give me the best weight-to-strength ratio with least condensation and a proper vestibule? Christien Pretoria, South Africa

We have a great 20-year-old 14x14 Eureka family tent. This summer a branch came down and tore a 36 inch vertical rip in the tent. Can it be repaired? Is there a company here in Northern California that does that or a kit I can buy to repair such a long (clean) tear? Gloria Millbrae, CA

What sleeping bag do you recommend for two to three days near the Virginia section of the AT? I tend to be a warm sleeper and hike spring through fall. Is there a single bag that will meet my needs? Matt Fairfax, VA

We are in need of a new tent! Our wonderful ten-year-old, well-used Walrus has served us well, but the dog ate the vestibule two years ago and the duct tape is old, the pole sleeves are starting to shred, and the poles are fatigued. We need to accommodate four people as well as one dog in the vestibule, and will be camping in the Idaho mountains. We typically car camp, but I would like to add short backpacking trips as our kids are getting older. We tried a tent from REI and we froze over Memorial Day. It is not uncommon to have snow on the 4th of July. We also camp in the more temperate areas of Oregon, so ventilation is good. I really want a new tent just like my Walrus, but I find the choices overwhelming. Can you help limit our options? Thanks! Love your column. Michelle Boise, ID

I've had my MSR Sweetwater Microfilter for about four or five years now. I used it two or three times without incident right after I got it, but it has been in storage ever since. Now I would like to start using it again. Do I need to worry about mildew or bacteria in the filter and tubes? Is there an easy way to clean the entire apparatus? Eric Pittsburgh, PA

Everything I've ever read or experienced says external fre backpacks are more forgiving to pack, better for trail hiking and cheaper than internal fre packs. I understand internals have advantages on rough terrain, but given all the benefits of external fres, why do they seem to be going extinct? I missing something? Chuck Pittstown, NJ

I was wondering why more people don't use a blanket to sleep in the backcountry. They are more temperature adaptable, lighter weight (for a given size), there just aren't a lot of options offered. What do you think? Josh Vallejo, CA

What is the minimum recommended thickness for a backpacking tent floor to prevent early wearing out of the tent? Big Agnes sells a Seedhouse 2 tent with a rated trail weight of 3 lb, 14 oz. It sells a Seedhouse SL2 tent—the se size and design except for different materials—with a 2 lb, 14 oz. trail weight. One difference that saves weight: a 1,500 mm polyurethane-coated floor for the Seedhouse 2; 1,200 mm for the SL2. Marshall Atlanta, GA

I find that whenever I sleep outside with friends, I wake up with by far the most condensation on my bag. I have a four-year-old 15-degree Marmot down bag. It is probably near the less-warm end of the spectrum of bags me and my friends use, but not outrageously different from everyone else's. Why do only I wake up freezing cold and drenched? Charlotte Duluth, MN

I'm planning a trip to South America this summer and want to invest in a water filter and/or purifier system. What do you recommend? Paul Salt Lake City, UT

Good campsites—close to water, a flat spot for tents, etc.—are relatively common. Great campsites are more elusive. To find yours, be sure to consider these four factors.

I've been a conventional tent guy for years, but the Hennessy Hammocks intrigue me. How much of an adjustment would it be a for a tent guy to switch to a hammock? Do they really live up to the hype? Andrew Shreveport, LA

Carry a featherweight load without leaving comfort behind.

I agree with four of your five "top gear innovations" picks, but would strongly argue that the Therm-a-Rest pad should be in the #2 slot over the humble Ensolite pad. While Ensolite pads were a good step forward, the self-inflating matt has done more to enable a good night's sleep in the backcountry than anything else. Jeremy Omaha, NE

My son is completing Cub Scouts this spring and moving on to Boy Scouts in the summer. I searching for a sturdy tent for his use in the Boy Scouts, who average about a three- to four-mile hike in on most of their trips. I would like to find a one- or two-person tent that would allow for his gear to be stored inside and still have some room for dressing and sleeping. The weather in our area (Southeast United States) is hot, wet summers with thunderstorms and moderately cold, dry winters. Cost is a consideration because I expect this tent to be replaced at least once before he finishes Scouts. Jack Charlotte, NC

I a 5'8" female and wondering if I should get a women-specific sleeping bag. Is there really a difference? I'm a very cold sleeper, so I'd like a zero-degree bag. I also don't want to spend $300 dollars on it. Any suggestions? Thanks. Jessie Baltimore, MD

I have a Moonstone bivy sack—it has seven graphite rods with both graphite and metal ferrels (similar to tent poles). Does Moonstone still exist? If so, how do I contact them? If not, is there another source for these graphite rods? Geoffrey Cbridge, MA

What is your recommendation for a largish two-man tent? We're both six foot, two inches tall. I'd like to use it for an upcoming AT thru-hike, starting in Georgia in January, and also for some winter Pennsylvania camping. Any chance we can find one that weighs under five pounds without sacrificing durability? Luke Scranton, PA

I was thinking about buying a zero-degree bag. I winter cp once or twice each year and won't go if the temps will be too low (So far the coldest may have been 10 degrees). I have a buddy who is dead set against inexpensive brands. Is there really a warmth difference between an inexpensive zero-degree bag and an expensive one? I not a warm sleeper but a "cheap son-of-a-gun." Are there any recommendations that you can make? Marty Morgantown, WV

What is the lightest solo tent, one that also offers serious protection in storms? Peggy San Jose, CA

Don't let the dark of winter slow you down. We tested two dozen next-gen lights to bring you the six best and brightest.

Why don’t more people use a blanket to sleep in the backcountry? They seem more temperature adaptable with a lighter weight for a given size. There just aren't a lot of options offered. Josh Vallejo, California

What is the minimum recommended thickness for a backpacking-tent floor? Big Agnes’s Seedhouse SL2 tent has a trail weight of two pounds, 14 ounces, with a 1,200mm polyurethane floor coating. Should I instead opt for the similar Seedhouse 2, which has a 1,500mm floor coating but weighs three pounds, 14 ounces? Marshall Atlanta, Georgia

I’m an avid day-hiker, and now I want to do weekend and longer hikes. I have thought about doing the Appalachian Trail but need tips on light-weight gear. I was in the infantry in the army and spent time in the mountains of Afghanistan, so I know weight is crucial. Any help? Jeremy Carrollton, Georgia

How long should you hold onto a sleeping bag? When cleaning out our attic, we ce across some sleeping bags that are from our college days (we’re 35 now). Is it time to retire them? Sarah Frisco, Texas

My wife and I are trekking in Chile and Argentina next summer, so we’ve decided to exploit the circumstances and replace most of our equipment with newer and lighter items. Can you build the ideal shopping list for us? Yonathan Tel Aviv, Israel

Could you recommend a good freestanding, lightweight two-person tent? My husband and I often take multi-day kayaking trips and cp on rocky islands (e.g., in Sweden or Canada) where pegs can be difficult to use. We’d also like to take it on hiking trips of up to a week. We tend to go places that aren't particularly warm and can be wet. Katrina Cbridge, United Kingdom
