Use it for carrying groceries to your exes house, or to return overdue library books to the local library. Holds pretty much anything except small children, and swords larger than 3 feet.
Super tough materials like 1000 denier Cordura and Ripstop. Stain and tear resistant. 'Tear' like 'rip'. Not 'tear' like 'crying', but it's tough enough that it probably wouldn't cry, even if it could.
