SUBSALVE USA Quad Bags are multi-purpose bags that can be used as a lift bag, on a reel as an upline float, as a drybag, or as an inflatable dive flag/float. The Quad Bag is four bags in one! Recover your ultimate prize from the depths, mark your location with an upline, tow the flag to warn off boaters, and after the dive put your suit into the bag to keep your car dry. A must for tech divers, wreck divers, beach and boat divers. SUBSALVE USA Quad Bags are manufactured of high-strength, lightweight, vinyl- coated nylon fabric and roll up small enough to carry on every dive. They are screened on both sides with a bright red divers down flag for high visibility. Every Quad Bag comes complete with a velcro tie strap, bottom waterproof closure and a brass snap. Quad Bags are equipped with an oral inflator and an optional lanyard-operated dump valve.
