Sweating in a Winter Wonderland

Whether you bike, sled, ski, skate, or surf, here´s the best gear for frolicking in the cold

Winterize Your Bike

A typical bicycle tire puts about an inch of rubber on the road at a time. That works in dirt, but it´s not nearly enough tread to get a grip in deep powder. With the Ktrak aftermarket kit, your mountain bike floats above the snow and weighs only five pounds more. $540; ktrakcycle.com

Sled Like a Pro

The Eurosled AvaLuge Ice Model-a seamless piece of polyethylene plastic inspired by Olympic luges and steeredthe same way-zooms down hills at up to 60 mph. Only the runners’ stainless-steel inlays touch the ground, reducing friction and increasing speed. Careful. $240; 3playinc.com

Ski and See

The Zeal Optics Link PPX are the first goggles that are both polarized to cut glare and photochromatic to automatically darken according to the lighting conditions. They´ll let you see the tree-avoiding it is your responsibility. $160; zealoptics.com

Surf Warmer

If you prefer your winter rides in liquid form, keep your lips from turning blue with the Rip Curl H-Bomb heated wet suit. Two lithium-polymer batteries power waterproof, fiber-based heating elements along your back to keep your core warm. About $700; ripcurl.com

Skate Faster

The 1.7-pound Easton Synergy 1500C hockey skate doesn´t sacrifice power to save weight. The first-ever one-piece carbon-composite boot has no joints to rob it of rigidity, so it responds quickly and evenly to movements from your foot. $450; eastonhockey.com
