This is a Cybertron backpack. It's been used sparingly, so I think it's in the category of spare equipment. The right shoulder strap is missing (photos 3 and 4). The following is from the Amazon page: Waterproof 900D (zippers are not waterproof) External dimensions: 20"(H) x 12"(W) x 8.5"(D) / 50cm(H) x 30cm(W) x 22cm(D) Molle system
