The MERLIN Folding Backpack is a light-weight 'escape-and-evasion' style backpack that folds into itself forming a small MOLLE-compatible packet which can be attached onto belts or other modular platforms. When unfolded, the main compartment of the pack will hold approximately 17 litres of gear. A totally separate back compartment equipped with top D-ring can hold a hydration reservoir, flat items such as maps/documents, or a folded towel/jacket. Two separate frontal pockets allow organization of smaller items. Our unique zipper pull limiter system allows user to adjust the direction of lower pocket opening depending on the pack's expanded or contracted state. Important note: the body of the MERLIN„ backpack is made from tough 420-denier coated nylon fabric (internal seams finished, of course) to take advantage of its ability to fold into a small space. Frontal pockets are made from 1000-denier coated nylon fabric.Maxpedition Hard-Use Nylon Gear is designed and constructed to withstand extreme conditions; in other words, we expect you to USE IT HARD in demanding situations and environments.
