I'm looking for a backpack for traditional, one-day, multi-pitch climbing. Which is the best one? I'm inclined to the Marmot Ascent 40. AndreaSao Jose

I am looking for a solid pack that is large enough for a bivy, a 32- to 45-degree down sleeping bag, an inflatable pad, and food for a night stay. But I also want to minimalistic. There are so many choices. Any suggestions? What should I be looking for? William Oakland, CA

I'm going to Peru for a week-long hike to Machu Picchu. I think the tour guides carry the large gear (tents, food). What backpack should I get? My local store suggested an Osprey 40 but I really have no idea what to get. Help! Thanks.ChrisLouisville, KY

I need the perfect present for my boyfriend's birthday! He's a cyclocross racer, mountain biker, skier, rock climber, and camper, and loves all outdoor gear and tools. Any great ideas within the $150 range?? -Sara Las Vegas, NV

I need a cool, new commuter bag. What do you recommend? The Editors Santa Fe, NM

FREERIDER’S DELIGHT It’s tough to find a backcountry pack that carries skis as well as a snowboard, but the 1,600-cubic-inch Pro 2 excels at both. An easy-to-use retract­able-cable system can handle even the fattest of powder skis, and it can accommodate snowboards horizontally or vertically, making it the best board-hauling…

Mountainsmith’s Modular Hauler storage system is built around cubes that measure 15 inches to a side. In that space, the Bike Cube Deluxe holds (and organizes) tools, a changing mat, clothing, eyewear, shoes, and a helmet. mountainsmith.com…

TOUGH BUT LIGHT Purists will love the Needle: It's an alpine pack that's been stripped of everything but the essentials. What's left is a supremely tough sack capable of handling your most epic days, but still weighing less than three pounds. The trick is putting the weight where it counts.

Good for Backcountry If the devil is in the details, this daypack is an unrepentant sidecountry sinner. Whereas most packs have one or two really smart touches, the Spindrift has half a dozen: a bit of mesh at the bottom of the avy-tool pouch so snowmelt can…

BASIC BAG If you could turn an old metal lunchbox into a ski pack, it would look like this—a utilitarian, bargain-priced hauler. The 1,647-cubic-inch pack held all the tools we needed for a daylong ski-mountaineering trip, stayed out of the way when we spent a morning making laps at Vail,…

This 2,520-cubic inch duffel, made from recycled materials, held a yoga mat, water bottle, and post-yoga clothes with room to spare. Plus the inside has organizational pockets for your cell phone, ID, and more. prana.com…

Good for Backcountry Pricey, comfortable, and tough, the Pro Light Tour was the luxury SUV of our test. There are no cupholders, but with a separate pocket for tools, vertical-carry ski straps, and ice-ax loops, everything else has a place. Plus there’s ample padding and just enough…

GATE HOPPER The 1,098-cubic-inch Silo 18 is an ideal choice when you’re jumping between the lifts and the sidecountry. Three stash pockets (one internal, two external) help you keep track of quick-grab items. The polyethylene back panel is just tough and stiff enough to make a solid base for ski…

KEEPS YOU COOL Admit it: Ever since you retired your fanny pack, you’ve missed being able to hike in the heat without soaking your T-shirt. With a curved suspension that lets air flow across your back, the Garmsal cools without compromising its carrying ability—or your cred. The crossed aluminum stays…

Old-School Cool A 1,950-cubic-inch daypack made out of merino wool? Yup. And it’s not a greenwashed gimmick, either. For starters, the merino wool here bears little resemblance to your favorite sweater; the yarn is worsted and given a ripstop treatment so it’s durable yet light. While the overall design is…

CHAMELEON When worn alone, the Outtabounds’ detachable 728-cubic-inch yo-yo pack was perfect for riding lifts. Insert it into the main pack and you have a 2,300-cubic-inch combo with stable support, effective compression straps, and simple carry system (lash your board vertically or skis diagonally). It proved the perfect package for…

VAUDE‘s ROCK 45+10 PACK. Its front crampon pocket keeps sharp points away from your jacket and rope, and its single-clip holsters fit everything from mountaineering tools to leashless axes with and without grips.

Smart and Fast In an actual emergency, the last thing you want to do is fumble with zippers. Which is why Marmot designed the Backcountry’s external snow-safety-tool pocket with double zippers and a sturdy pull loop: You can rip it open with one quick tug. It’s just one of many…

With nine pockets (including a hideaway bottle holder) and a magnetic closure that makes getting at junk a cinch, the burly nylon Stroll is the perfect personal assistant. 1 lb, 380 cu in; merrell.com…

BEST EVERYDAY PACK Consider the RPM a showcase pack from the less-is-more school of design. Climbers who loathe extraneous doodads will love the lean construction, but so will anyone looking for a simple, lightweight, do-anything hauler. On hikes and even long runs, the padded (but frameless) back panel and well-cushioned…

Most Breathable Seems like 2,000 cubic inches is the magic number when it comes to versatility—just big enough to max out on a fast-and-light overnighter but not too big for a day hike. And size isn’t the only thing the top-loading Spectro AC gets right. It was the most breathable…

THE PLAYER Instead of carrying your iPod in your jacket, stow it safely in the padded compartment of this 1,281-cubic-inch pack. The controls and phone jack mount on the ergonomic shoulder straps, and you can work the buttons with gloves on. Tunes or no, the Audex has ample room for…

Backcountry Staple At three pounds, the Cruise is light enough for quick tours and sidecountry laps, but at 30 liters there’s also just enough space to load up for a full day in the backcountry. An external shove-it pocket is the perfect size for climbing skins or a lightweight down…

Ski-Mountaineering Master With straps, loops, and holders designed specifically to carry skis, snowshoes, a helmet, ropes, ice axes, and trekking poles, the 40-liter, ski-mountaineering Spindrift is without a doubt the most versatile pack we tested this year. Even more impressive is how intuitive it is to affix all of the…

This was the most secure daypack we tested this year. Credit the superstretchy harness system, which twists with the body. Smart: The Maya’s internal compression system turns the pack into a tight bundle in one pull. 1.6 lbs, 1,040 cu in; gregorypacks.com…

MOST WATERPROOF When Moab's worst rainstorm in years coincided with our weekend plans, the Dryshield prevented a soggy retreat. In conditions that would have soused a lesser pack's contents, the 500-denier, polyurethane-coated packcloth kept our stuff bone dry. Its streamlined features—there's little more than mesh pockets and ax loops on…

Top Ultralight Lunch-hour hikes. Mountain-bike rides. Long trail runs. At 600 cubic inches, the Fluid 10 is just big enough to fit the essentials—shell, camera, lunch, etc.—without any wasted space. The light, ridged polypropylene frame­sheet gives it some stability (and a bit of ventilation) without adding too much bulk or…

FEATHERWEIGHT At just two pounds, the Light Speed makes good on its name while delivering ample space (915 cubic inches) for a day of sidecountry stashes and booter building. Plus, it withstood a beating during tight glade runs at Colorado’s Beaver Creek, thanks to poke-proof 600-denier polyester fabric. There are…

Board Sport Unbuckle the Blade’s padded back flap, place your snowboard across the pack horizontally, rebuckle, and you’re off. Not only is the process as quick and easy as it sounds, but testers liked the way this design balances the board’s weight, even if it’s not ideal in every situation…

Good for Backcountry This was our favorite pack for skiing around the resort. With its low profile, the Agent sits comfortably on a chair and stayed glued to our backs, even when hopping tight chutes out of bounds. Better yet, because the loops for its simple and…

Made from recycled plastic bottles, this backpack keeps your surf stuff organized with thoughtful features like a seam-sealed wetsuit pocket, tarp-lined surf-wax keeper, and insulated cooler pocket. dakine.com…

SPEED DEMON Can a running-oriented hydration pack double as a daypack? Yes, if it's designed as well as this one. During trail runs in the mountains above Santa Fe, the Riff's compression straps, foam back panel, and perfectly sculpted harness made for a stable, slosh-free ride. Yet on hikes the…

Urban Hiker Half messenger bag, half backpack: That’s the easiest way to describe this 1,500-cubic-inch urban hauler. With a well-cushioned 15.4-inch laptop pocket and a DWR-coated, splash-resistant flap closure, it’s the perfect pack for biking to work or walking to the coffee shop. Thanks to the same breathable mesh padding…

Heading out the gate? This low-profile and lightweight (three-pound) pack comfortably carries skis, avy gear, and a helmet. There’s also extra back protection and an insulated hydration-tube sleeve. mammutusa.com…

Workhorse The 29-liter Mazama doesn’t have any whiz-bang features. Rather, words like “solid,” “sturdy,” and “intuitive” kept popping up on tester cards. Plush padding on the hipbelt and shoulder straps made it comfortable for long hauls, it’s reinforced in all the right places (including the waterresistant zippers), and multiple side…

Go ahead and cram this pack full on the hottest day. The stiff Butterfly suspension supports a load of rocks, and a mesh panel lets air cool your back. 3.1 lbs, 1,830 cu in; www.mammutusa.com Bonus: A rain cover is included.

Hiking, biking, trail running—we did it all with the Diablo. There’s just enough space in this 352-cubic-inch pack to stash an emergency shell, a bike pump, and a snack, especially if you take advantage of its waist-belt pockets, two external stash pockets, and bungee strap. But what really makes…

TAKE IT ANYWHERE Small enough for short jaunts, cool enough for the heat of the desert, and tough enough for the mountains. The Direct 28 does it all, and for a sweet price. The abrasion-resistant 210-denier nylon body—and doubly reinforced bottom—is made for alpine abuse, while an aggressively arched frame…

Simple and Smart Although they’re best known for making school bags, JanSport also has a long track record making technical performance packs—like the 2,074-cubic-inch Salish. From long day hikes to more gear-intensive scrambles to local crags, it consistently received high marks as a comfy, versatile pack. An externally accessed hydration…

MOVES WITH YOU Built with a light plastic frame and hipbelt system and an Allen-wrench-adjustable pivot point that attaches a separate shoulder harness to the pack, the BA1 offers independent hip and torso motion. Testers were skeptical at first: The BA1 seems like a lot of money for a lot…

Like the Energise, this pack’s air-cooled suspension prevents sweaty-back syndrome. Stretch-woven side pockets didn’t rip when caught on branches, and zipper finger loops made gloved entries a cinch. 2.6 lbs, 1,500 cu in; www.ospreypacks.com Crowd pleaser:It’s available in five different capacities.

This smart little pack brings a dash of technical know-how to a street-savvy bag. In town, you can remove the hip strap to dial back the crunchy-guy factor, while a bit of reflective piping increases your visibility when riding or walking in the dark. Wherever we were, the water-resistant…

1.The Patrol 35 nails the most important feature in a winter pack: how well it carries skis or a snowboard. TNF’s Fly-Trap carrying system compresses skis (A-frame or diagonally) or board (vertically) amazingly close to your center of gravity. The result is excellent stability—which made me feel balanced and…

Minimalist Nomad The beauty of the 3,050-cubic-inch Backtrack is its versatility—it’s a shoulder bag, a suitcase-style hauler, and a backpack with a detachable daypack—which we enjoyed on backroad rambles in Colorado. Deploy the adjustable suspension and head out with a week’s worth of goods bundled with dual compression straps. The…

Good for Backcountry Scrap—not Trash—would be more accurate: This 2,196-cubic-inch daypack is made out of leftover bits of sailcloth. It’s a cool story, but it also makes sense: The fabric is remarkably weatherproof and durable. The rest of this streamlined pack is equally clever. Aluminum stays lend…

SPARTAN AND PACKABLE No suspension system, extraneous buckles, or even a sleeve for a hydration bladder. And that’s why we love the Cierzo: It’s perfect for those times when you’re not sure you’ll need a small daypack—be it a business trip to San Francisco or a river trip with the…

Paper-thin silicone-treated nylon, compact size, and a frameless suspension make the Iso superlight—and a good choice for speed hikes. The tradeoff is decreased abrasion resistance and minimalist support. 1.6 lbs, 1,200 cu in; www.gregorypacks.com…

A mash-up between a college book bag and a classic daypack, the streamlined, 2,000-cubic-inch Shrike was surprisingly versatile. The suspension system—basically a padded back panel and shoulder straps—isn’t anything fancy, but if you don’t overload it (30 pounds, max), it’s plenty comfy for long hikes. Around town, the front…

DAY TRIPPER If your passion is touring, get the nimble Drift. “It’s the perfect size and profile for the typical day trip,” said a tester who put miles on the pack in the Colorado backcountry. Skis or snowboards strap on easily and stay rock-solid, with three different carry options. On…

Stowaway Because it packs down to the size of a grapefruit, this sling always made its way into our suitcase. We liked it as much for what it lacks (superfluous straps, extra weight) as for what it has (a phone pocket and comfy shoulder strap). 7.7 oz, 427 cu in;…

LIFESAVER Should you get caught in a slide, the AvaLung-equipped Anarchist can improve your odds of survival. The device—which is built into this comfy 1,953-cubic-inch pack—redirects the poisonous carbon dioxide you exhale, delaying the formation of a suffocating “ice mask” around your face. It reportedly can keep avy victims alive…

VERSATILITY CHAMP “Exactly what a daypack should be,” said one tester—and that’s the best way to describe the Laguna. With the ability to expand from 500 to 800 cubic inches, the Laguna’s just big enough to fit a shell, snacks, and a few extras. The airflow system’s mesh padding doesn’t…

Judicious use of siliconized nylon—bolstered by 1,000-denier reinforcements—make the Bodie both water-repellent and durable while keeping weight low. 2.5 lbs, 2,000 cu in; www.marmot.com…

Lift lines to skin track. Heli-drops to sidecountry laps. Snowshoeing, skiing, snowboarding. We subjected more than 20 new winter packs to serious use and abuse to whittle the list down to seven, a mix of generalists and specialists. But if you’re anything like us, you want one pack…

HARD CHARGER Unless you huck off every cliff in sight, donning body armor is overkill. But a little back protection makes sense for anyone who ventures into exposed, big-mountain terrain. The multitasking, 1,450-cubic-inch Razor is built with a Shield Back System: foam-wrapped polyethylene pads that are part of the internal…

Catchall Versatile is this bag’s middle name. The big opening makes it easy to pack for a weekend in a hurry. With both a shoulder strap and handles, it transforms from purse to gym bag easily, and the polyester interior dries quickly after toting sweaty yoga clothes. 2.1 lbs, 1,586…

1. Thanks to the 690-cubic-inch Bandit’s low profile, we barely noticed it while riding lifts. And when we wanted to leave the gates or head out for a quick backcountry tour, this pack was the perfect size. 2. The Bandit’s sleek look belies its utilitarian nature. Inside, you’ve got…

This large daypack is adaptable, tough, and loadable both from the top and through a U-shaped front zipper. Expandable side pockets stow flip-flops, and two zippered, detach­able pouches in the top com­partment organize small stuff. The gel-padded harness system is cushy yet supportive. 3.5 lbs, 2,130 cu in; lafumausa.com…

This climber-friendly pack has a removable hipbelt—a plus when wearing it with a harness—and a weight-shaving detachable lid. Brilliant: Tool attachments double as bottle openers. 2.9 lbs, 2,150 cu in; www.mountainhardwear.com…

Good for Backcountry Winter hikers, stop making do with ski packs: The 1,700-cubic-inch AirZone Snow is designed specifically for you. The back panel is more like one found on a warm-weather backpack. Rather than flat padding, there’s an airy, suspended mesh that adds both comfort and ventilation…

MINIMALIST This featherweight was designed for rando racers—think running uphill on skis, and then bombing back down—but easy access and minimalist design also made the 290 (as in grams) our testers’ choice for the resort. It easily fits under a jacket, but at 1,098 cubic inches, it’s big enough for…

Daypack We’re suckers for chamois-lined sunglass pockets, but what really endeared this pack to us was the easy-to-pull straps that cinch it down into a neat bundle for the times your hike turns into a trail run. The externally loading sleeve makes refilling a hydration bladder (not included) a breeze.

LIFT SERVANT One tester described this pack as “a wallet on your back with water.” The 275-cubic-inch Scorpion’s two-liter bladder kept testers hydrated both on quick tours before work and skiing all day at the resort. Lunch, a spare pair of goggles, and an extra layer fit in the main…

Organizers will appreciate the many pockets in this petite daypack. There’s also a hydra­tion sleeve and a bottom pocket for the stow-away rain cover. Despite all these features, it’s (relatively) light and stream­lined: The harness system and removable waist belt are supportive but not bulky. 2.7 lbs, 1,500 cu…

Don’t let your daypack turn into a black hole. The compact Ray allows easy organization, thanks to dividers in the main compartment, deep exterior side pockets, and a separate pocket for your hydration system. It’s also light and secure enough for running. I ran the rigorous three-mile Jud Wiebe…

Good for Backcountry The Free Rider is not so much a backpack as an armored hydration pack, perfect for ducking in and out of the resort. The back panel is actually a protective foam-and-plastic plate—similar to those worn by motocross riders—that flexes with you while you ski…

HUT CHAMP A two-in-one pack is the smartest choice on a hut trip, and the Windpack is one of the year’s best. The main pack’s 2,550 cubic inches easily swallowed sleeping bag, clothes, and tequila on a three-day hut tour in Colorado. And chasing face shots, the detachable, 500-cubic-inch yo-yo…

One-Night Stand The Axios has just the right number of features, like organizer pockets and a stretchy catchall pouch on the front, but (thankfully) no rat’s nest of straps. The mesh back panel also did its job cutting down on sweat, as we experienced on a 16-miler in the Grand…

I want to buy my cousin a pack to carry his skis up the mountain. He's 18 years old, just started school in Flagstaff, AZ. Should be some good back country stuff for him to try. What's a good pack for back country skiing? Nelson Alexandria, VA

I am looking for a good backpack for my camera gear (Nikon D300, 2 lenses, etc), but also carry my hiking gear on day trips. I have a Gregory Z30 as a daypack, but that is not easy for carrying my camera gear. I also tried some camera backpacks...but those don't have enough space and technical capabilities to support a long day hike. Any suggestions would be very helpful. -Dave Vienna, VA

I’m searching for a great multi-purpose backpack for graduate school. I'd like to use it while biking to carry my laptop, books, and some dog accessories. In addition, I'd love to be able to throw a bladder in there along with some hiking gear. Any suggestions for me as to what route to go for a super sweet new pack?—LizDenver, CO

WHERE TO USE IT: One glimpse of Longs Peak’s 1,500-foot vertical east face and you’ll know why you came: This 14,259-foot Colorado mountain is no mellow slag heap. The 15-mile round-trip hike gains 5,000 feet and demands an alpine start; afternoon lightning storms are a given. You can also tackle…

I'm new to hiking and would like some good clothing suggestions for day hikes in late spring/summer/early fall. I'm just not sure where to start.—TaraWashington D.C.

I live in Las Vegas and I spend a lot of time rock scrambling at Red Rock Canyon and I need a durable backpack. It seems that most packs are designed with weight over durability in mind. Unfortunately, Red Rock Canyon presents many "tight" spots which tend to damage these lighter-weight materials when they inevitably "drag" on the sandstone. Any suggestions?—BrianLas Vegas, NV

My biggest problem with my current daypack is that my back gets very sweaty, even with a quick-dry shirt. Do you know of any daypacks that allow for more airflow between the pack and my back? Christopher St. Louis, MO
