The Alpinlite is a 20F mummy sleeping bag built with high-fill-power goose down in continuous horizontal baffles, letting you shift loft where you need it. A full-length draft tube, down-filled collar, and snag-free zipper seal warmth in, and the 6ft 6in length with a left-hand zipper fits taller sleepers.
It is made for three-season backpacking and shoulder-season alpine trips where packed weight matters but a cold night is a real risk. The trim mummy cut traps heat efficiently while the down compresses small in a pack.
Western Mountaineering has handcrafted down sleeping bags and garments in San Jose, California since 1970, filling and sewing each bag in-house.
