At just 1 lb 3 oz., the SummerLite is the lightest bag we 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.
