For high speed ascents and light-and-fast hikes, nothing beats the premium, high warmth-to-weight ratio of down. The North Face Diez Vest for women is the lightest down vest they make and is streamlined for high performance as part of TNF's Summit Series(R) collection. Stuffed with lofty and highly compressible 900-fill down (yes, you read that right), this North Face vest has a drawcord at the hem to help seal in warmth and will stuff inside one of the 2 front zippered hand pockets to save pack space. Designed with an Alpine fit, this winter vest decreases bulk with a snug fit that will keep you warm under your weatherproof winter jacket. When you beat the rest of your party to the summit, you'll be stoked to pull out The North Face Women's Diez Vest for some instantly gratifying warmth.
