The Molle system consists of a series of secure webbing loops designed to attach items to each other. The Molle stick threads through the laser etched slots on the ORG_M_04 - or via another set of Molle loops on many of our other bags - securing the pouch to the pack. The ORG_M_04 comes with the option of an adjustable/removable strap, giving you a compact bag with smart organization that you can carry on its own or as an expansion to a larger bag.
