How do you make a bicycle that never needs lube, never leaves grease on your pants, and always delivers smooth pedaling? Simple: Ditch the chain.

For its new Soho commuter bike, Trek replaced greasy metal links with a dry belt. Unlike other attempts at such bikes, the Soho is silky smooth to pedal. And it’s the first to offer multiple speeds, using an eight-gear transmission inside the rear-wheel hub.

Wear the same 23-ounce jacket whether it's slightly cool or downright frosty outside: A new North Face coat becomes more than a third warmer when it's turned inside-out. Its versatility comes primarily from the way the insulation is sewn. The quilted squares on the metallic -- or cool -- side have small pockets at their edges. When worn on the outside, the pockets stretch open and allow air to flow in and out. When reversed, the jacket pushes the pockets together and traps air inside them, providing greater warmth.

Keep your digits toasty without swaddling them in layers. Outdoor Research’s PrimoVolta gloves pack an electric heater that can stay hot for six hours—more than twice as long as others—yet are still flexible enough to grab your jacket’s zipper pull.
