Kokatat Maritime Assault Suit System (MASS) consists of an over-garment with neck ring or any other tension relief and ventilation system, which can be used as a combat suit in maritime, land, airborne, shipboard, and transitional environments. To keep the user comfortable, the MASS shall provide the greatest degree of water vapor management and must be durable enough for rugged field use. Lightweight and durable, the MASS is currently used by Navy SEAL and SWCC Teams for on- and over-water tactical operations. The GORE-TEX® membrane and latex seals provide completely waterproof protection from the elements.
