Stylist Notes The "TANKER" series, which was announced in 1983 and is synonymous with PORTER. It uses an original 3-layer structure fabric developed with the motif of the US Air Force flight jacket "MA-1". The 3-layer fabric of nylon twill (surface) + polyester cotton (middle layer) + nylon taffeta (back) is very light, and the soft feel of the bonding material and the vivid rescue orange on the back are attractive. This series is full of the thorough attention of Yoshida&Co. craftsmen in all processes from cutting to sewing and parts. There are three colors available: black, sage green, and iron blue, and the back side is a vivid rescue orange. In addition, They have adopted an aluminum fastener, which was rare at the time of its release, and made it so that the metal fittings such as snap buttons and saddle snap can change over time, so that the paint will peel off.
