Wow! Look at you—so chic. Aspen is all you need to stay warm, look good, and keep it simple. We've taken the basics of a puffer, shaved off the bulk and kept all the core warmth in. The Quilted materials add style without too much fluff. The soft sherpa-backed neck and chest ensures extra warmth where you need it most. And our signature buttonhole for leash access means you'll always have a place for your pup's harness or leash as you're out on adventures together.
