The Alpha Liner for the OneSystem BK.

With the Alpha Duo Liner you get the best of two worlds: The inside of the liner consists of classic Alpha Gel, which is extremely flowable and greatly adapts to anatomical structures. On the exterior, the fabricless liner consists of extremely durable Alpha Silicone with a high-quality satin finish.

A One Gel Sock is enclosed with each liner; it serves as a textile liner cover which, during the OneSystem BK fabrication process, gets shaped to follow the edge of the prosthetic socket.
