Since being introduced in 1983, PORTER's synonymous "TANKER" series uses an original fabric developed with the motif of the US Air Force flight jacket "MA-1". The three-layer fabric of nylon twill (front) + polyester cotton (intermediate layer) + nylon taffeta (back) is very light, and the soft feel of the bonding material and the bright rescue orange on the back are attractive. In every process from cutting to sewing and parts, we express thorough commitment. Established in 1962, Porter Yoshida Kaban’s durable, practical and stylish military-inspired nylon bags are made exclusively in Japan. Fun fact: “kaban” is actually the Japanese word for “bag.” Dimentions: W 5 x H 7.5
