The black Vanguard USA Supreme 40F Carrying Case is a virtually indestructible, engineered hard polypropylene case that is airtight and built to withstand the most extreme conditions. The O-ring sealed case is waterproof to 16.5'. It has a three-piece foam set with a recessed interior for the top foam and an automatic pressure equalization valve. There are thick, quick release, easy-open latches that lock in place, and steel-reinforced lock holders for use with padlocks for added security. The case can be carried by a cushioned handle and it has anti-slip rubber feet.

This case received an award in Germany for design excellence.
