The boonie hat was introduced to the United States Armed Forces during theVietnam War, when U.S. Army Green Berets began wearing them in the field, along with Australian and Army of the Republic of Vietnam units. These leopard spot or tigerstripe boonie hats were locally procured, the camo cloth was usually salvaged from other uniform items or with the former from a parachute or made up by the tailor. The name is derived from "boonie", the abbreviated form of boondocks (itself originally American military slang derived from Tagalog bundok, "mountain", during the Philippine-American War).
A-TACS foliage green camouflage boonie. The wide rim helps keep the sun of you when in outdoor environments. The band around the hat allows you to attach extra foliage for specific concealment needs.
