Porter-Yoshida & Co's 'Things Helmet' tote is a brilliant all-rounder because it's sizeable enough to work as an overnighter but also looks neat as a day bag when you want to transport your laptop. Made from durable nylon, it's equipped with front zipped pockets and a detachable padded shoulder strap. The cubic eye-piqué panelling on the back makes it comfortable to carry, while the elastic cord around the base is from the very first design that Mr Kichizo Yoshida created in 1923.
