The Snap Rebound is a great medium/larger sized pad. It folds in half making it very easy to transport and store. This pad has straps on its underside which are detachable and can be put in a pocket on the Rebound to stop them from getting dirty or worn. The materials used on the outer is of the Rebound crashpad is (100% recycled) Polyester with a TPU coating, a TPU coating protects the foam and outer material from dirt, grease, oil and rain (it's not waterproof) which makes the Rebound more durable and able to serve you longer.
