SUUNTO's Ambit3 Sport is one of the most advanced GPS watches available. It has a heart-rate-monitor chest strap and records data when you're running, cycling, swimming, or mountaineering. The Sport also gives you access to hundreds of routes, fitness apps, and training programs. It can overlay a run, hike, or bike ride on a 3-D topo map (share it with friends) and is water resistant to 100 feet—good for snorkeling. Mountaineers should get the Ambit Peak, which tells you the altitude and barometric pressure and sends you storm alerts. Starting at $400 ($500 for the Peak).

How can you avoid the dork factor of strapping on an action cam but still record the day's best skiing or cycling moments? ZEAL's anti-fog HD2 Camera Goggle has a video camera built into its frame and a rechargeable battery that lasts up to eight hours. It takes photos in high enough resolution to print in large format (12 megapixels). And the camera lens is 170 degrees wide to capture all the action, which you can monitor via the in-goggle viewfinder. Even with gloves on, controlling the camera is easy thanks to oversize buttons. Zeal's app lets you upload shots right from the lift. $499, including an 8-gigabyte memory card.

If counting calories and steps is all you care about, clip FITBIT's unobtrusive Zip on your belt and go. The 1.1-by-1.4-inch tracker records how many steps you take (with every goal reached, you earn a badge) and calculates how many calories you burn based on your age, height, and weight. Fitbit's software can also create tailored food plans. $60.

Not sure if you'll have access to a wall plug? ENERPLEX's Packr Executive backpack keeps your gadgets' juices flowing wherever you are. On the front is a rugged, waterproof three-watt solar panel that powers a USB port. Inside, there's a padded laptop sleeve, a panel pocket, and enough room for a change of clothes. Charging a dead phone takes about five hours in full sun. At night, Enerplex's Jumpr Stack batteries will keep you going. $130 for the backpack; batteries start at $40.

Take the quantified-life trend to the extreme by sticking TRACE’s action sports tracker, which is the size of a peanut butter cup, onto your surfboard, skateboard, or skis—it’ll track your every jump, trick, and turn, telling you your speed, distance (horizontal and vertical), and calories burned. The sensor is shockproof and waterproof. Want to show off your sickest carve or longest ride with all your numbers appended? Trace’s stats sync with your GoPro footage, which you can upload to Dropbox. In addition to adding your stats, the snow-and-surf app cuts right to the action and color corrects, too. $200, including a tube of 3M adhesive.

If you have trouble counting your sit-ups, push-ups, or box jumps, WAHOO’s Tickr X workout tracker can help. Its 2.75-by-1.5-inch strap-mounted sensor has a motion detector that, with an app, counts your reps and how many calories you burn. You don’t even need your phone in hand for full functionality: The chest-strap monitor has built-in memory that captures your output, then syncs with your phone après. It’s compatible with more than 50 apps. $100.
