At just 1 lb 3 oz. (6' length), the SummerLite is the lightest bag Western Mountaineering make 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 32°F, which is based on extensive field testing. The EN13537 "Comfort Rating" (a.k.a. "women's" or "cold sleeper") is 41°F, and the "Limit Rating" (a.k.a. "men's" or "warm sleeper") is 32°F.
