Weighing in at just 1 lb 3 oz, the SummerLite is the lightest continuous-baffle sleeping bag that Western Mountaineering makes. These baffles allow you to regulate the temperature of the bag by shifting the down on top of you in colder temperatures, or underneath you when things warm up, making for a very versatile summer bag. Hard to believe in a bag this light, but the SummerLite even comes with a full length zipper and an insulated draft tube for extra protection from the elements. Western Mountaineering designed this bag for the lightweight fanatics who have provided them with feedback, criticism, and motivation to continue producing the lightest down products available.
Like all of Western Mountaineering's bags, the SummerLite is made by hand in San Jose, California. Their down is sourced from free-range mother geese who are never live-plucked or force-fed.
