HypaBand Underwrap is a non-slip, thin, lightweight foam material that is applied to the skin prior to taping for added comfort. It is highly recommended to use for prolonged periods of bandaging. HypaBand Underwrap is ideal for sensitive skin and is perfect for prevention of chafing and to prevent skin irritation. The non-adhesive polyurethane foam binds to itself and not to the skin and reduces trauma when removing the bandage. HypaBand Underwrap can also be used inside all kinds of athletic footwear for enhanced comfort.
