This is the "TANKER" series, PORTER's signature line, first released in 1983. Inspired by the U.S. Air Force flight jacket "MA-1," it utilizes an original three-layer fabric construction. The three-layer fabric of nylon twill (surface) + polyester cotton (intermediate layer) + nylon taffeta (back) is very lightweight, and the soft feel of the bonding material and the vivid rescue orange on the reverse side are attractive features. From cutting to sewing and parts, this series is packed with the thorough commitment of Yoshida & Co.'s craftsmen. The color is black, with a vivid rescue orange lining. In addition, aluminum zippers, which were rare at the time of release, are used, and the paint on the snap buttons and metal fittings like carabiners is intentionally designed to peel off with use, allowing for aging and changes over time (see photo). This is a shoulder bag characterized by its oval shape. The front and back pockets have wide openings for easy use, and the main compartment has a clear pocket, making it a functional item. - Color: Black - Size: Approximately W27cm x H18cm x D9cm - Number of pockets: 2 exterior, 1 interior
