The Propper Hot Weather OCP Uniform Pants are designed for wear in extremely hot or wet conditions. Made to military specifications from a 57% nylon / 43% cotton fabric blend, the improved hot weather combat uniform (IHWCU) pants are a lightweight, breathable alternative to the scorpion OCP uniform used by the U.S. Army and Air Force. Engineered to dry quickly and perform better in the heat, these summer uniform pants offer top-level comfort in arid environments. They feature newer, more streamlined cargo pockets as well as 100% nylon knee reinforcements. These pants are built to meet strict regulations and are approved for official uniform wear.
