It's a Down Sweater with more down. The Hi-Loft is built with a lightweight 100% recycled polyester shell, and packed with warm, highly compressible 800-fill-power goose down. It can be worn as a midlayer or stand-alone layer. It has Deluge® DWR (durable water repellent) finish, and two handwarmers, one internal, zippered security pocket. Drawcord hem seals in warm air and keeps out cold and spindrift, and stuff sack included. Regular fit!
