A true best-of-class parka, our layerable and generously proportioned Fishtail comes with an impressively durable, hydrophobic shell fabric of polyester, cotton, and nylon. The shell fabric alone is worth discussing. Super supple, amazingly soft, yet dense enough for water to simply bead and bounce off. A removable quilted liner with hood and wool blend rib knit cuffs instantly serves as a 2nd jacket as weather dictates. Taking its cues from the original M-51 parka, many of the original’s construction hallmarks are faithfully embraced while at the same time utilizing modern materials for a better solution. Every detail painstakingly considered and built to last. This is our most protective garment, for all elements.
