BSN Medical Delta-Rol® Cast Padding, Synthetic adds comfort underneath a cast. It's made with synthetic acrylic fibers that won't absorb and retain moisture. This is important in helping maintain healthy skin and won't cause skin maceration from moisture build-up. It's also latex-free to not cause skin irritation for individuals with a latex allergy. The roll wraps around a limb easily and stretches as needed when trying to narrow the padding to cover smaller regions without needing scissors to cut to size.
