A Relwen classic, faithful to the original manufacturer construction specifications as produced in 1951 for the U.S. Army. Our latest version of the M-51 employs a matte finished nylon dobby shell fabric with breathable waterproof laminate backside. A slimmer fit than the original oversized box, our fishtail parka is still a bigger garment built for coverage and layering. The parka can be worn in 3 stages: minus faux fur hood liner, minus insulated liner with rib cuffs, or full bore with both linings in tact. The hood liner’s outer facing possesses a copper wire that allows the fur facing to be tightly shaped and extended beyond the face to create an opening that the fiercest sub 30 degree wind cannot penetrate.
