This bag is inspired by civilian helmet bags from the 1950s to the early 1960s. It is crafted with highly waterproof nylon fabric on the exterior and features internal stitching with quilted polyester cotton to provide cushioning, effectively protecting the contents. The design is minimalistic, with slip pockets on both sides of the interior for storing flat items. It can be carried crossbody or by hand. The surface is embroidered with a dragon and tiger pattern, carrying a similar meaning to the Yokosuka souvenir jacket.
