PORTER 's signature series, Tanker, has been reborn using 100% plant-based nylon, the world's first material to be successfully mass-produced. This tote bag (L) has an attractive basic design and can store A4 files and a 15-inch PC, making it the perfect item for everyday use both on and off the job. It has a wide gusset, which allows it to store a large amount of items and stand on its own. The side pockets on the exterior can hold a 500ml plastic bottle. It comes with a removable strap, so it can be used in two ways: by hand or over the shoulder. The handle is designed to be long, so it can be used over the shoulder.
