The Exped Comfort Sleeping Bag lives up to its name when you're backpacking faraway destinations. Its 700-fill down insulation has a 25F temperature rating, packs small, and weighs less than three pounds for easy trekking. Exped treated the exterior fabric with DWR for durable water-resistance that sheds moisture and light rainfall. The full-length zipper wraps around the entire footbox to convert the sleeping bag into a quilt for greater versatility, and the zipper couples with other Comfort sleeping bags for room for two.
