The Shellback Tactical Dump Pouch is a super low profile pouch that quickly deploys by a single pull tab. This dump pouch features a dual u-shaped zipper with a one inch pull tab that releases a secondary 260 cubic inch bag to hold empty magazines. The secondary bag features a drawstring closure that secures the contents in the pouch while the pouch is secured to webbing or a belt via nylon straps with hook closure. Once your mission is complete, the secondary bag can be folded up and tucked back into the pouch for the next mission.
