Sewn to military specifications, the Propper Air Force OCP Boonie Hat is the official boonie hat of the United States military. Approved for active duty use, the hat keeps you cool and dry with vent holes that allow moisture to escape and air to enter. An adjustable chin strap fastens the hat securely in a comfortable position. The 50/50 NYCO ripstop fabric is also supremely durable and designed to last a lifetime. To ensure that you stay out of sight from infrared detection, the Propper boonie hat is also NIR compliant.
