Pure wool bonded with a breathable membrane to resist water and wind while retaining a luxurious texture and drape. We've returned to a 2-layer version that is softer but it still is fully seam sealed on interior. We heard customers and added better 2-way zipper, faux suede details, four exterior and four interior pockets. Double vented. Genuine horn buttons. Dry clean.
