The E-Z Mount Zip-On QD Pouch can easily hold a 6-cu. ft. bottle or similarly sized object. An elastic drawstring top securely closes the top of the pouch while a nylon elastic band can be placed around the neck of an air bottle to hold it snugly in position. The zipper attachment allows the Pouch to be easily added and removed from the Ranger LTD BCD making storing and refilling your pony bottle a snap. To mount the Zeagle E-Z Mount Zip-ON QD Pouch on other Zeagle BCD models the Zip Universal Mount Adapter can be used. The Pouch measures 5.5" x 12" x 4" (14 cm x 30.5 cm x 10.2 cm) and is made from a durable mesh with taped and sewn edges for added strength and durability.
