Precisely sized to hold seven M4 30-rnd mags, stacked either vertically or horizontally, the Rollypolly also functions as a dump pouch for shotgun shells, M4 magazines, or pistol magazines. Alternatively, the Rollypoly is a multi-purpose utility pouch suitable for evidence collection or general storage.

It has snag-free elastic shock cord closures that pull from the posterior side of the bag. A velcro flap which maintains the pouch in its folded position, doubles as a lid or can be concealed completely within the bag.

In its folded state, the Rollypoly is a mere 3" x 3" x 1.75", saving precious belt space, and can be attached to MOLLE or PALS webbing by means of Malice Clips (sold separately ). A top loop allows the Rollypoly to be piggy-backed using a Duraflex Siamese SlikClip (included). Grommet located on the bottom allows for quick drainage.
