Porter-Yoshida & Co Tanker Square Shoulder Bag in Iron Blue – Nigel Cabourn

Porter-Yoshida & Co Tanker Square Shoulder Bag in Iron Blue


The “Tanker” series has become synonymous with Porter since its introduction in 1983. It uses an original 3-layered fabric inspired by the US Air Force “MA-1” flight jacket that is both durable and lightweight. Comprised of nylon twill as the surface layer, a polyester cotton blend as the mid layer and nylon taffeta as the inner layer, the vivid orange colour lining has become a key feature in this range. This series remains one of Porter’s iconic ranges and is representative of the thorough attention and commitment of Yoshida Kaban’s craftsmen.

With a compact square shape, this Shoulder Bag is deceptively spacious with several inner and outer pockets and compartments. Designed with functionality in mind, the main compartment fully opens out and is equipped with straps to secure your belongings. The main compartment is easily accessible through a zip on the rear of the bag, and the detachable shoulder strap means the bag can be used as a stand-alone pouch with its carry handle.
