PORTER 's signature series, Tanker, has been reborn using 100% plant-based nylon, the world's first material to be successfully mass-produced. The Boston bag (L) is a distinctive item with its half-moon design. It has enough capacity for everyday use when you have a lot of luggage, as well as for short trips of about one night. The side pockets and hook-and-eye pockets on the exterior are convenient for storing and retrieving small items such as smartphones. A removable strap is included, allowing you to use it in two ways: as a hand-held bag or over the shoulder.
