Keep warm on chilly nights with the Dolomite 20F/-7C Sleeping Bag from The North Face. The Heatseeker Eco Synthetic insulation provides an excellent warmth-to-weight ratio. It’s highly compressible and very durable. It’s made from 50D ciré polyester using 30% post-consumer recycled materials. Unzip the full-length zippers on each side and use the sleeping bag as an insulated campground blanket. The wraparound footbox zipper keeps the bag flat, and the rectangular shape provides plenty of wiggle room, for warmth without restriction.
