Designed for close-range use in dense jungle during jungle warfare by the South Vietnamese Armed Forces and adopted by US Special Forces during the Vietnam War. It features narrow stripes that look like brush-strokes of green and brown, and broader brush-strokes of black printed over a lighter shade of olive or khaki. The brush-strokes interlock rather than overlap.
All Hopper covers are sewn with matching color thread and black bias. Made from a custom fabric called SRF, a foam with polyester laminated to both sides. All hopper covers can be flipped inside out for an all black cover. Newer generations will have black thread on the inside.
