The WillowWood Alpha Silicone AK liner, featuring a symmetrical profile engineered to provide extra protection to the distal femur and allow the liner to be rotated for extended wear, is available through Chico, Calif-based O&P distributor Cascade. According to the company’s website, the liner uses a proprietary, platinum-cured, medical-grade silicone intended to ensure comfort and performance for transfemoral amputees.

The blend of silicone, vitamin E, and skin conditioners reportedly results in a smooth surface that is non-greasy, non-tacky, and comfortable against the skin. The company notes that the liner also uses Select fabric designed to control pistoning without using a dual matrix, yet allows for circumferential stretch for easy donning.
