The outer material is made of industrial material woven with 210 denier 6 nylon strong thread. Originally, this fabric was not intended to be dyed, and was used as a base fabric for rubber boats. 

Inspired by the lining of a military jacket, the emergency color orange is used for the interior, and ripstop nylon is quilted. Up to 4 different types (4 colors) of nylon tape are used in key points to create a realistic military feel. Except for some items, the interior pocket is removable and can be used as a single pouch.
