THERABAND Exercise Mats have been re-engineered with a new and improved material to provide maximum cushioned support for comfortable floor exercises and to help protect against injury. Made of high-density polyethylene, a lightweight non-PVC material, the mats' fabric-like surface is waterproof, wear resistant and designed for repetitive use. Easy to care for, they are washable with soap and water. They also include pre-drilled hanging holes and two elastic straps for easy storage options.
