Porter-Yoshida & Co. - Porter-Yoshida & Co.’s black Tanker 3Way briefcase is an updated version of the 1983 original style that’s named after its choice of three carry options – by hand, over the shoulder or cross body. It’s made in Japan from a durable triple-layer nylon twill and has a bright orange lining – a riff on traditional bomber jackets – and is equipped with internal zipped pockets and buckled straps
