The Tanker is an iconic series from PORTER that debuted in 1983, and its inspiration comes from the MA-1 flight jacket. This series is still very popular today, and here we take a look at the latest Day Pack to get the Tanker treatment. An all-black exterior is made from three layers of synthetic materials for durability. On the exterior, a nylon twill fabric sandwiches polyester cotton material in between nylon taffeta on the interior. Rescue Orange lining is also another of its iconic trademarks, referencing the MA-1 jacket. This day pack also comes equipped with a matching pouch that can fit digital cameras, electronic gadgets or smart phones. B Jirushi Yoshida online shop in Japan is stocking this item right now.
