The durable and extremely lightweight Women's SUMMIT L6 FUTURELIGHT Down Belay Parka from The North Face was made for long, cold belays in variable weather. The North Face's proprietary Futurelight technology is the most lightweight, waterproof, breathable membrane on the market. It coats the Pertex Quantum GL nylon ripstop that can hold up against the worst that nature can throw at you. The 800 fill ProDown insulation is the warmest you'll find and has even more repellency for total impermeability. The offset baffle stitch eliminates cold spots, and the attached, fully adjustable, helmet-compatible hood for complete coverage in any blizzard. With a full range of mountain-ready features, it's ready to help you conquer the tallest peaks.
