In the 1940s the US Navy was experimenting with many different styles of jackets that would meet the demands of the rough duties on deck. Jackets for sailors especially under arctic conditions needed to be warm, functional and durable. Until 1943 it was either the Deck Zip or the Deck Hook jacket that saw service. In 1943 a completely new design was introduced. The N1 Deck Jacket. Loved by sailors the newly introduced N1 Deck Jacket was warmer, more functional and durable than its predecessors. Firstly made in a dark blue/black it was soon replaced by a khaki/greenish tone for better camouflaging purposes at beaches. Today the N1 Deck Jacket is a highly sought after collectors’ item due to its iconic status it has gained during WW2 and the post war period.
