100% polyamide. Water-repellent duck down insulated fabric. Full zip fastening. Stand collar. Stowable hood. Raglan sleeves. Two zippered interior chest pockets. Two zippered slash pockets. Ribbed cuffs and hem. Regular fit. The Vintage Mythic Jacket from Pyrenex is a down behemoth with a real rousing moniker. Pyrenex has been making these since the 70s, and not a lot has changed design-wise since then. Just the way we like it. They have kept up with the times in terms of fabrics though, endowing this doozy with water-repellent, wet-look taffeta thats been stuffed to the gizzards with down. We shouldnt need to tell you how toasty this is.
