The Waterproof Satchels feature a thick durable wall construction with a 360 degree seal for water resistance. Available in two sizes, these satchels feature two locking points for extra security, a rubber over mold handle for easy carry, a recessed lid for extra work space, rust proof steel pin hinge construction, and a durable polycarbonate lid with ribbing design providing extra strength for crush resistance. The open core interior can be custom molded or inserted with die-cut foam to safely store and protect your valuables. (products are not tested for complete submersion underwater).
