Originally designed to be worn as part of a full 'Winter Flying Suit' (WFS), the 'WEP' jacket was produced for the U. S. Navy between the 1950s and 1970s. Buzz Rickson's have chosen to faithfully reproduce the late C-Type WEP jacket know for it's distinct V-tapered cuff detail and dark olive colour. 

Compared to other well known American flight jackets from the period, the WEP jacket takes a more utilitarian approach with two large patch pockets on the chest, and a single pocket on the left arm. A chinstrap keeps the ribbing closely fastened for warmth, while interior waste tabs are included with the intent to fasten to the matching trousers. The jacket is interlined with a dense wool felt to provide warmth and structure, while the gathered waistband keeps the shape neat and tidy.
