The Desert Digital Camouflage Boonie Hat by Rothco. In use by the US Military since the Vietnam War, the Boonie hat has proven itself useful for providing shade and camouflage. Equipped with "branch loops," the user can insert local foliage into the hat itself to provide additional natural concealment. The attached chin strap provide extra security making sure you don't loose your cover. This is great for arid desert climates.
