At just 1 lb 3 oz. (6' length), the SummerLite is the lightest bag Western Mountaineeringmake in a continuous baffle construction. Our goal in designing this bag was to make it as light as possible without eliminating key features or function. The result is a fully-baffled bag that weighs only 19 ounces and features a full-length zipper with insulated draft protection! The SummerLite is a dream come true for lightweight backpacking fanatics.

The 6'size weighs 1 lb. 3 oz.

The 6' 6" size weighs 1 lb. 5 oz.

Western Mountaineering rates the bag at 32F, which is based on extensive field testing. The EN13537 "Comfort Rating" (a.k.a. "women's" or "cold sleeper") is 41F, and the "Limit Rating" (a.k.a. "men's" or "warm sleeper") is 32F.
