1943 CPO Shirt – 570 gsm – Navy Wool – Pike Brothers

A timeless classic from the U.S. Navy. The 1943 CPO Shirt in a heavy wool blend is designed to withstand extreme cold, whether as an insulating mid-layer or as a robust overshirt.

This version of the 1943 CPO Shirt is made from a heavy and durable wool blend weighing a full 570 g/m² (approx. 17 oz). The material consists of 80% wool and 20% polyamide, a combination that provides the natural warmth of wool while the polyamide increases durability and shape retention. The shirt was originally developed for the U.S. Navy as an extra warm layer under the iconic N1 Deck jackets, but its robust quality means it can easily be worn alone as an outer garment.

The design follows the original military specifications with an authentic cut that allows for layering. The shirt is equipped with classic anchor buttons, a distinctive feature of maritime clothing from this era. With two large chest pockets and a robust construction, this is a garment made to last for generations.
