Dahon Flo - $2,300
Two Wheels to Go. "Folding mountain bike" is the sort of phrase that makes me shudder -- kind of like "brakeless bullet train" or "Al Qaeda Airlines." But the Dahon Flo ($2,300; www.dahon.com) is such a well-crafted and sweet-riding hardtail, you'll drop any preconceptions the moment you jump in the saddle.
Thanks to a coupler near the bottom bracket and an ingenious use of the seat post to secure the frame, the bike builds up or breaks down in less than 15 minutes and can be stowed in a suitcase (to circumvent airline surcharges). Unlike other folding mountain bikes, the Flo's old-school steel frame—Reynolds tubing, not cheap aluminum -- delivers a great ride whether on the steeps of the Alps or the rocky headlands of South Africa's wild coast.
And its parts are excellent: Avid disc brakes stand out, 27-speed SRAM X9 shifters never miss a beat, and at 23 pounds, the weight is on the money. Now, if only someone would invent a folding helmet.
Suunto t3 - $149
Wrist-Top Coach. Heart-rate monitors are pointless unless you are training correctly -- and with the vagaries of individual body types, that's easier said than done. The Suunto t3 ($149; www.suunto.com,) however, does the work for you. Just program your personal fitness profile, then during your workout the t3 analyzes your heartbeat and records training levels to optimize improvement.
REI Sub Kilo - $230
Body Bag. Forget that the REI Sub Kilo ($230; www.rei.com) is rated at 20°F -- that's debatable -- but it's still the best three-season sack out there. The 29-ounce, 750-fill-down mummy is lighter and warmer than premium bags costing a hundred bucks more. Newly redesigned, it has a larger hood (for pillow creation) and an internal pocket for your headlamp and glasses.
