Layering is huge when it comes to hitting the slopes or any active cold-weather activity. While the Race AirPush from Tenson is light enough to fit under a shell, it can just as easily stand alone. Tenson’s formula for light, down-like insulation keeps me warm on the cold days and dry on the warm days by wicking away moisture. Made with recycled polyester, this coat is one that can be purchased with a clean conscience. Not only is it thoughtfully constructed, it features large zippered pockets, a detachable hood, and an adjustable waistline. The Race AirPush is versatile, and one I keep in my arsenal for almost all excursions: alpine skiing, hiking, snowshoeing, or even Nordic skiing, to bundle up in afterward. Available online; $239.
