Alpaca Lined Whipcord N1 Deck Jacket - Indigo

The classic N1 deck jacket was first produced for the US Navy in the early 1940s. Much copied since then, it has become a style icon in its own right. The Iron Heart version remains pretty true to the original on the basis that "if it ain't broke, don't fix it". The one major, but unseen, change we've made is the addition of interlining to increase wind resistance. A seriously warm and stylish winter jacket, and being indigo, this jacket will fade with time.
