This lightweight, low-bulk insulation compresses small and resists water even better than regular down fill. Rest easy its certified to the Responsible Down Standard (RDS), meaning no ducks were force-fed or live-plucked. Versatile 4-in-1 design This isnt just any old 3-season bag; it can also be used as a liner inside a second sleeping bag for especially cold nights and unzipped for use as a quilt. Alternately, pop open the short zipper on the side to create a cooling vent without letting it all hang out. Durable water repellent (DWR) finish A sleeping bag this versatile is going to get used. It might get damp. Its probably going to get some dirt on it. But with a forgiving DWR finish, it shrugs all that off and never stops doing its job: keeping you toasty at night.
