This is a prototype "sample" of a New Balance S7 fire retardant clothing system piece. This piece was probably one of several sent out to various commands for testing or this could have been used at the factory for reference. This closely resembles the USMC's Inclement Weather FROG shirts. This jacket is of a heavy, stiff material. It does not have pockets expect for the shoulder pocket on the right side. The sleeve cuffs have thumb holes as shown.
