Our ballistic fabric is a densely woven (1200 denier) material similar to that used in the flak jackets worn by soldiers during WWII. It resists tearing and punctures and will hold up much better against destructive behaviors than traditional bed covers. Rip-Stop is an additional feature that further reinforces the strength of the fabric. This grid-like weave of even stronger fibers helps minimize damage by stopping any small punctures from becoming gaping holes.
