ALPS Mountaineering Wisp Sleeping Bag

The Wisp works as a standalone summer mummy bag perfectly suited for warm nights, where typical 30-degree bags may be too warm. The fleece liner interior delivers a soft, comfortable layer next to the skin that doesn't promote sweat like some bags with nylon interiors. A left-side zipper also allows the top of the bag to be opened, keeping the upper torso cool and the lower torso and legs comfortable.
