This is a great casual jacket from Athleta called the Chill Bomber. It’s a navy blue windbreaker material on the outside but with a nice soft jersey knit lining. This jacket feels nicely made and is a medium weight. Little quality touches around the zipper and pulls. Pre-Owned but like new, size XS.
