The DermaSaver Arm Tubes are soft and loose with ample air flow reaching the skin allowing for greater healing ability whilst offering protection. Two cushion layers of MicroSpring Textile protect fragile skin from friction and pressure that can cause skin tears, bruising and abrasions, plus another two layers to protect vunerable elbows. Available in a selection of sizes. Simply measure the circumference around the widest part of the forearm. For borderline measurements, choose the larger size to ensure comfort.
