The messenger-bag version of our versatile Ditch™ bag can load-out numerous modular containers on the front surface, but keep them hidden/protected under the unassuming flap. The flap compresses bulk with over-sized lock-buckle-straps (which are also removable from the bag). The flap itself can be removed in a few seconds (it is mounted on the rear with an ingenious flat-lock system). You can also change flap colors with aftermarket flap-purchases. The flap has a large loop-fastener area which also fits our available i.d. window patch. The patch can be secured to the flap w/ our Civilian® Rewind™ cable gear retractor. The MOD™ also now features a luggage-handle velcro/webbing mount on the back for convenient airport travel and a direct access flap zipper (you don't have to open the buckles to get to the main bay area.)
