"PORTER FORCE" is a casual series with a military touch and a motif of coincidental color differences rarely seen on military items. The biggest feature is a slight color irregularity between a front pocket and a body, to create a look of various lots. All types come with a removable pocket that can be used as a pouch. Industrial material is used for outer material, which is made of 210 denier 6 nylon high tenacity yarns. With quilted ripstop nylon in orange (emergency color) is used for lining.
