The Story

The classic N1 deck jacket was first produced for the US Navy in the early 1940s.  Much copied since then, it has become a true style icon in its own right.  The Iron Heart version remains pretty true to the original jackets on the basis that "if it ain't broke, don't fix it".  The one major, but unseen, change is to add an additional interlining to increase wind resistance.  This piece is a truly warm winter jacket.

For FW22 Iron Heart added an oiled version to the range of N1s, giving improved water-resistance to the jacket.  Due to the nature of whipcord and its reluctance to absorb, the heavy oiling of the fabric increases its weight from our standard 12oz to approximately 14oz.
