First commissioned in 1959 to make USA military gear that could withstand the elements, Alpha Industries is a Tennessee-born label known for iconic bombers, flight jackets and parkas (in other words, outerwear with major street cred). The N-3B has a flight nylon shell with contrast-orange nylon lining. The full-length storm flap, adjustable hood and storm cuffs make this snorkel parka perfect for protection. Features four pockets and Alpha's signature zippered utility pencil pocket.
