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.
