A prosthetic sheath is most commonly worn against the skin underneath any prosthetic socks. When worn against the skin, aprosthetic sheath will protect your residual limb against friction by absorbing movement between your sheath and stump socks. A prosthetic sheath acts as a low tech perspiration barrier. Sheaths are knitted with nonabsorbent synthetic materials such as stretch nylon . Nylon allows any perspiration to pass through the prosthetic sheath and into your prosthetic socks, offering you a feeling of dryness.
