The C-3 was standardised on May 28th 1936. Made from a 1/4 inch fleece depth shearling, it was designed to be worn under a flying jacket or suit as an extra layer of insulation.
It has a simple 8-piece construction with a zip closure down the front.
Our C-3 is the first since WWII. Made to the same specification, from our 1/4 inch North American sheepskin.
