"Chatooga" model duffel dry bag is easy to close, guaranteed waterproof and has a huge opening. Order this bag if you're tired of messing with roll-down closures that require "burping" inside air and would like to be able to see what you've got inside. Patented extruded rubber "ZipDry" closure is an industrial-strength version of a Zip-Lock Bag, only easier to close. Chatooga model is 1,800 cu. in., 21" long and 10" in diameter. Made of double-coated polyurethane over a base of 420 denier nylon packcloth, it's tough to beat for durability. Closure is the full 21" length so it opens wide.
