Purchased several years ago and used a few times, but it has been stored unused since my commute changed. Square-shaped combination of navy nylon material and leather. The nylon material is a tough material also used in the inner fabric of bulletproof vests. The fabric, which has passed rigorous flame resistance tests, is both strong and lightweight.
