With its excellent mix of breathability and warmth, this layer is perfect for winter trekkers. It's formfitting without being restrictive and features a French-terry interior lining for maximum comfort. Wrist covers and a chest pocket for keys are useful on the trail – while a reflective logo means it can be a great outer layer for an early-morning dog walk. And don't worry about overheating: Ventilated pit zones and the half zip at the neck help shed excess heat. [$85; salomon.com]
