DESCRIPTION

Western Mountaineering proves you can have a 20F mummy sleeping bag with a wider cut at less than 2lb with the Alpinlite. But don't think that cutting weight means cutting features. The Alpinlite Sleeping Bag still has a full-length zipper and passive draft collar to seal in heat when you're rolling around at night. The Alpinlite's low weight is achieved by using the highest quality down available and an ultralight Pertex fabric. The Pertex is naturally very water resistant because of its density and very breathable since it doesn't rely on laminates and coatings. The high quality down used by Western Mountaineering offers more warmth per ounce and has much greater longevity than any other insulating fiber.
