Designed for uptempo activities, these lightweight-breathable jackets use air-permeable fabrics that wick moisture. Water and wind resistance vary dramatically.
BEST FOR: Cross-country skiing, cool- weather running, fast-and-light climbs.
WHY THIS ONE: Made from Gore-Tex’s stretchy Windstopper X-Fast fabric, Millet’s Trilogy Limited WDS Hoodie is surprisingly weatherproof given how lightweight it is. Worn with a thin base layer, it was ideal for midwinter marathon training in windy and snowy Minnesota.
