The early attempts to make a camouflage uniform centered around coveralls. After field trials, these were found to be hot, uncomfortable and dangerous to the wearer in times of disposing of bodily waste during combat. These were rapidly relegated to a work uniform, although they appear to have seen limited combat use, in both Europe and the Pacific. A few photos also exist of them being worn by tank crews. Our repros are made from the same cotton HBT as our USMC and Army two-piece camo uniforms. As usual, we copied an original- these do include the internal suspenders- which, after one use, you'll immediately see why most guys cut them out. Made with Talon brand zippers and Scovil snaps.
