The Maxpedition Rollypoly was developed to hold empty magazines and carry shotgun shells, but it’s also suitable for storing clothes when travelling. The Rollypoly folding bag, also known as a dump pouch in the USA, is ready to be worn on a belt, or can be attached to a Maxpedition backpack or webbing using 3-inch TacTie® Attachment Straps (sold separately). It can also be attached via a Slik Clip (included) to 2.5 cm (1-inch) wide vertical backpack straps. There is an opening at the bottom for drainage.
