Slap Happy This watch’s fumble-free solution to recording your splits: Smack it! The slap-sensitive face works great (and is especially useful when wearing the watch under long sleeves). Plus, the enormous display is very easy to read. Note: Accidental bumps can trigger the timer, and the wrist strap is not…

Finally, an excuse to have a bottle opener on your key chain without having to go back to college. www.buckknives.com…

Air scoops on the shoulders, a full-size back vent, and the softest, most porous nylon of the bunch makes this an ideal pick for intense or humid runs. Style kill: See-through fabric reveals ugly inner workings. 5 oz; asics.com…

Good for Trail More nano than puff. This half-zip, one-pocket, and lightly insulated synthetic pullover is remarkably bulk-free, considering how warm it is. We loved it as a midlayer on cold days at the resort or as a light jacket on chilly fall outings. 10 oz;…

Buy More Passes With its subtle herringbone-like weave, square buttons, and asymmetrical front pockets, the Mohave is stylish in a low-key way. So when we saw the reasonable price tag, we figured Scott blew the budget on flair. Wrong. This insulated hard shell is brimming with smart touches, like wrist…

Split the difference between superlight and full-featured: This packable polyester shell has a fleece-lined collar, hem drawcord, and chest pocket that doubles as a stuffsack. 5.8 oz; cloudveil.com…

Colltex’s supple, smooth-gliding mohair skins use a pressure-sensitive glue that binds tighter when weighted but is still a breeze to peel. We received these in late spring, so we can’t speak to durability. But first impression? Wow. colltex.com…

Daily Dose Lance may shill for FRS, but it’s hard to tell whether quercetin—the dominant ingredient in this company’s drinks and chews—really ramps up your mitochondrial power plants and endurance. Small, company-funded studies say yes. We say quite possibly. frs.com…

A top-quality helmet with a (literal) twist. The inner shell rotates on impact, potentially reducing the twisting forces transmitted to your brain. Eight offset vents provide extra protection from pointy objects (like a branch or ski pole), but they restrict airflow a bit. TAGS: rotates, best protection…

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…

Unlike the regular stuff you get at the gas ‘n’ go, this Gatorade mix has 79 g of healthy sugars (no high-fructose corn syrup) and much more salt—350 milligrams. Buy it online or at a health-food store. gatorade.com/performance…

Talks You Through It This small device delivers basic speed-up/slow-down instructions (based on your heart rate, pace, and a workout you select at micoach.com) through an earbud to help maximize your workouts—best for those who are new to training programs. Drawbacks: lots to fumble with, and no…

Perfectly tailored, ultralight, rustle-free, and, if you opt for the shield-your-eyes neon-green color, unbelievably car-repellent. Translation: It’s our favorite do-it-all shell. 3.3 oz; sugoi.com…

Good for Backcountry The inner synthetic layer disperses sweat on contact for quicker evaporation, while any condensation from your jacket instantly beads right off the wool exterior. After wearing it nonstop on three Cascade volcanoes, our tester was addicted. dakine.com…

Hot Deal With top-shelf synthetic insulation (PrimaLoft Eco), a tough, waterproof outer fabric, and all the creature comforts you could want (including nine pockets, pit zips, a powder skirt, and a goggle chamois), the 4 Pines has all the ingredients of a high-performance, full-featured resort parka. Normally, all this adds…

The poly/nylon Synapse scores a near-perfect balance between breathability and weather resistance. Despite the bantam weight, it includes a stowable hood, hem drawstring, and stash pocket. 4.1 oz; orgear.com…

This compass weighs just 1.2 ounces, and its smash-proof housing also contains an inclinometer. brunton.com…

The Best Energy Blobs Of the many of chews we’ve tested over the years, these are our favorites. They come in great flavors (like fruit smoothie and pomegranate), are easy to digest, and are made almost entirely from natural, non-GMO ingredients (like tapioca syrup and honey). honeystinger.com…

CW-X‘s REVOLUTION TIGHTS will serve you well. Through a miraculous feat of fabric engineering, they combine light, stretchy CoolMax sections with firm muscle-supporting panels without a tangle of seams.

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…

“Extreme” might be overkill, as these are just jelly beans (sugar plus corn syrup) with 50 mg of caffeine plus a little salt and vitamins. Pop them before workouts for a nice energy surge—100 calories, 25 g sugar. Midrun, we found them hard to chew. sportbeans.com…

Band Aider New to running tech? Start here. A foot pod and waterproof wristband measure time, total distance (90 to 95 percent accurate), and speed (ballpark), then uploads the info into basic Web-based tracking software. nikerunning.nike.com…

Weighing little more than half an ounce, the Two Can is either the lightest little knife we’ve seen this year or the smallest pair of scissors. www.kershawknives.com…

Large, stretchy back panels dump heat, while a more tightly woven polyester front blocks the wind without feeling like plastic wrap. 8 oz; columbia.com Bummer: A bulky internal stuffsack in the left pocket adds unnecessary weight.

Good for Backcountry This mostly wool-and-nylon button- front was a midlayer before the term “midlayer” existed. Ski with it over a base layer, then wear it with a T-shirt to the bar. smartwool.com…

Puff Daddy We were impressed by how well the Mission’s pit zips regulated temperature on a mild midwinter trip to British Columbia, but there was plenty of stuffing (500-fill down) for the most frigid test days, too. So if single-digit readings are commonplace at your home resort, check out this…

An infusion of stretchy, breathable polyester fabric (in the back, underarms, and wrists) makes this ultralight one of the year’s best aerobic pieces. Fit is accordingly trim. 4 oz; patagonia.com…

With a new third antenna that delivers more accurate distance-to-victim measurements, a pull-tab-activated search mode, and a directional display, this is the simplest and most intuitive beacon on the market. 8.8 oz; backcountryaccess.com…

Vasque’s lightweight (11.4-ounce) but firm Transistor FS shoes have a low chassis that keeps you in touch with the trail. vasque.com…

For jackets, you can go for either a base layer and a thick, thermal soft shell—like SALOMON‘s STRETCHY SWIFT MIDLAYER HOODY with integrated mitts—or a lightweight shell.

AN ELEGANT BRUISER Imagine the offspring of a Ferrari Testarossa and a Toyota Land Cruiser: precise handling, hard-duty construction. That's the essence of the Alpine Pack 50. It's a no-nonsense, climber-oriented pack with zero bells and whistles to create weak points. The 420-denier nylon—reinforced with 1,000-denier fabric on the bottom—should…

A new, refreshingly not-so-sweet endurance drink, Xood has no artificial anything. But each 16-oz packet does have 30 g of carbs (natural maltodextrin and fructose), 105 mg of sodium, and 2.5 g of whey protein. xoodhealth.com BummerThe concoction is too frothy to carry…

Front of the Pack A GPS watch without compromise. The Forerunner 110 measures distance, heart rate (with $50 strap), and real-time pace. The interface is intuitive, uploading to a computer is easy, and the watch itself is smaller than a Reese’s Peanut Butter Cup. Add it up and you’ve got…

At just 2.4 ounces and 2.5 inches when stowed, this microknife conceals some oversize innards: seven tools and a pair of pliers for those on-the-go, clutch repairs. www.gerbergear.com…

Perforated side panels let out steam nicely, while a hem drawstring, an extra-tall collar, and soft chin padding help seal out the chill. 5.9 oz; merrell.com Bonus: Low-key style is coffee-shop friendly.

Good for Backcountry Stretch is right. This super-soft bamboo-and-poly shirt moves like second skin. Bamboo complements the speedy wicking of polyester with natural anti-stink properties. kombisports.com…

Luxury Comes Cheap Pata-Gucci? Not in this case. The Snowshot was one of the least expensive jackets in our test but also a tester favorite. Like the Cloudveil, it’s an ideal everyday, all-season jacket for Rocky Mountain resorts. It’s stuffed with the perfect amount of synthetic insulation. It’s waterproof. You…

A three-ounce jacket with a hood? Believe it. This water-resistant featherweight trims grams with a half-zip and paper-thin ripstop nylon fabric. It’s less breathable than others here but offers excellent rain protection. 3 oz; mammutusa.com…

Jimmy Odén’s new ski-mountaineering bible is so comprehensive—366 pages on route finding, equipment, avalanche safety, etc.—we’d shelve it next to Mountaineering: The Freedom of the Hills. But the stunning photography and hip design suggest a better home would be on the coffee table. freeskiingthebook.com…

Don’t fret about shorts—a breezy fabric, supportive liner, and pocket, like those on Patagonia’sseven-inch-inseam Long Haul Runners shorts, and you’re out the door. patagonia.com…

THE NORTH FACE‘s slim-fitting APEX CLIMATEBLOCK FULL ZIP JACKET, is all wind- and slushproof panels except the stretchy sides and forearms.

CLASSIC WEEKENDER If today's stripped-down packs are a little too austere for your tastes, but full-featured packs are too heavy, you'll find the Ridgeline just right. It's light enough for weekend duty but doesn't require a minimalist approach to packing. Go ahead and throw the espresso maker and extra vino…

Missed lunch? Don’t also miss your workout. These heavy-duty meal-replacement bars have 280 calories—38 g of carbs, 20 g of protein, and 6 g of fat—and taste pretty darn good. promaxnutrition.com BonusSome flavors have no high-fructose corn syrup.

Heart Matters A heart-rate monitor should be both intuitive and powerful. This affordable one does well on both counts, automatically telling you what heart-rate zone you should be aiming for and uploading your workouts to training software with an optional $55 FlowLink cradle. polarusa.com…

If you think catch-and-release is too prissy, unholster this seven-inch stainless-steel blade. With a retractable blade guard (which means less handle to get in the way when you’re slicing), this scalpel would make a sushi chef proud. www.benchmade.com…

With four easy-access storage pockets, a water-resistant iPod pouch, and a three-liter reservoir guaranteed against punctures for life, this updated classic is a smart pack for long rides and hikes. 1.4 lbs; www.camelbak.com…

Good for Backcountry Sugoi consistently churns out some of the best running apparel, and this midweight synthetic base layer—with built-in hood, integrated mitts, and half-zip for venting—is no exception. Plus the athletic fit and thumb loops mean it also works as an underlayer for slower pursuits.

Twofer The big selling point here is obvious: You get both a warm, burly ski shell plus a thick, synthetically insulated sweater that can be zipped in to boost the warmth. Both jackets are constructed with Columbia’s new Omni-Heat lining, a matrix of metallic dots that reflect heat back to…

For nighttime running on busy roads, flip this jacket inside out and you’ll flash like a human traffic cone, thanks to a fluorescent mesh liner and reflective trim. 8.5 oz; hellyhansen.com…

Cut extra long and packed with 800-fill down for extreme cold, this super-puffy kept us warm in near-zero temps and 30-mph winds on a 12,000-foot-high ridgeline. 2 lbs; 66north.com…

I’m also partial to ASICS’s Favorite Long-Sleeve shirt, which, despite being long-sleeved, is thin and cool enough to wear during summer speed work. asics.com…

When the weather is waffling, IBEX‘s merino wool INDIE ARM WARMERS have thumb loops—and are the perfect hedge against a cold start and a hot, sweaty finish.

One of the best weekend packs you can buy

These oat-and-chocolate-covered cookie-dough balls are savory and satisfying, with 11 g of protein and the same carb blend as regular PowerBars. But even with water, they’re a bit dry for midworkout fueling. powerbar.com…

Technical The synthetically insulated and DWR-coated Igniter is slim enough to slip beneath a shell on cold mornings at the resort. Worn alone, it held its own into the mid-twenties, and it packs down smaller than a volleyball. 1.4 lbs; TAGS: synthetic, great midlayer…

Along with having every other feature you can imagine (PC connectivity, workout logs, and more), the t3 can detect over- or under-training and help you adjust on the fly. It’s the sleekest model here, but its chrono settings can be tough to read midlap. suunto.com/training…

This featherweight back hugger stays in place during even the most jarring bob-and-weave trail running. Pack sparingly: There’s space for only energy bars, keys, and a light shell. The spongy back panel is soft but gets sweaty. Two-liter reservoir included. 12 oz; www.kelty.com…

The antimicrobial poly-and-wool blend is an excellent funk fighter. And the body-mapping construction—thicker fabric around the chest, thinner under the arms, and flexible sections on the elbows for mobility—works: It’s extremely comfy and better at temperature regulation. Note: Runs small and slim—the large fits like a medium.

Soft Touch “It just feels right,” said one tester. That pretty much sums up the Welder, and after we added up all the comments, it was clear that it was the most breathable, stretchy, supple, and comfortable insulated soft shell we saw this year. The Welder delivers enough water and…

1. Comfort: Go ahead, try and overload it. On treks in New Mexico's Pecos Wilderness and even ski touring in the Tetons, testers were unanimous: The Meridian carries like a champ. Credit the firm yet flexy composite frame-sheet that moves with your body, dual-density foam in the hipbelt that cushions…

Our favorite synthetic belay jacket in the test, the Enclosure is light, easy to pack, and slim-fitting. The supple recycled-polyester fabric and PrimaLoft insulation bottomed out around 10 degrees in a stiff wind. 1.6 lbs; cloudveil.com…

Compression socks are catching on, and for long, blister-free runs, I’ve become a fan of toe socks; Injinji’s Ex-Celerator Compression Toesocks combine the two. injinji.com…

SKINS SPORT SOX provide both compression and insulation for calves, which get colder more quickly than upper-leg muscles.

POCKETS GALORE Are you forever looking for ways to stash small items, like camera, snacks, GPS, sunscreen, first-aid kit, and more? The Nimble, with no fewer than seven pockets and three storage compartments, is your pack. “It's more organized than my kitchen!” said one tester. Even better, the Nimble still…

Good for Trail Easily the warmest jacket here, the XV is absolutely stuffed with top-tier down (850 fill) and wrapped in a tougher-than-average DWR nylon shell. It’s a bit heavier—but a lot burlier—than other down jackets we tested. 2.1 lbs; firstascent.com…

Technical This waterproof hard shell is stuffed with the same amount of synthetic fill as the Igniter (above), making it a bit warmer (and more windproof) but also, not surprisingly, not quite as breathable. Because it’s completely impervious to wet snow and sports a hood with a visorlike rain brim,…

The GT3 helps track recovery times and adjusts your zone alerts quickly midrun—great for fartlek training and intervals. The manual is a little puzzling, but the payoff is worth the decoding time. cardiosport.com…

If you already have a hydration reservoir and just need a more versatile pack to put it in, go for the Razor and its interchangeable hipbelts. Use the minimalist strap for running with a light load; swap in the padded belt when you cram the pack full for a day…

Good for Backcountry The waffle-grid backing inside this stretchy fleece zip-T dramatically boosts surface area, speeding sweat evaporation. The smooth exterior lets it slip easily into midlayer sleeves. Our only gripe: The neck hole is too large. (You lose heat.) corelayers.com…

Except for a few tiny holes on the brim and back, the Rival has no vents. The result is better weather sealing during storms but a sweatier head come spring. It’s a high-volume helmet. TAGS: simple, well-priced…

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.

Because 20 percent of the 650-fill insulation is goose feather, rather than higher-quality down, this standard-issue puffy is incredibly affordable but still toasty in the low teens. Bonus: Waterproof-breathable Pertex fabric protects the sleeves and shoulders. 1.3 lbs; outdoorresearch.com…

In cool weather, Marmot’s Trail Wind Jacket rarely feels clammy, thanks to its moisture-wicking fabric and underarm vents. marmot.com…

SAUCONY‘s wind-resistant, hunter-orange PROTECTION GLOVES have great features (terry snot wipe, big reflective patch, breathable palm panel, and nifty USB-rechargeable, clip-on light).

A quick-connect hose makes these reservoirs easy to refill (you can remove the reservoir without rethreading the hose and bite valve through the pack's hydration port). 48–100 ounces; nalgene-outdoor.com      …

Because it’s lined with thick sheets of partially recycled synthetic insulation (PrimaLoft Eco), you get big-time warmth without looking like the Michelin Man. Compresses down to volleyball size and is trim enough to wear under a storm layer. 2.2 lbs; mountainhardwear.com…

Technical Top-shelf (800-fill) down + ultralight 15-denier ripstop nylon + an extremely athletic fit = as light and compressible a puffy as you can get. Our favorite feature: side zips that allow you to quickly dump heat or futz with inner layers. Least favorite: no zipper on the front kangaroo…

Looking for high performance at a low price? The N5 tracks lap times, stores data for 30 workouts, and offers the usual gamut of zone alarms, calorie counting, and percent of max—and doesn’t require a Ph.D. to use. nbmonitors.com…

An aggressively arched suspension with mesh panel lets air cool your back. The pack includes a two-liter reservoir and stows cargo for a long ride. Best for biking. 1.5 lbs; www.deuterusa.com…
