The 5 Ply Ultra Cushion Gel Liner™ is a two layer prosthetic liner made with cotton as well as a nylon reinforced-toe for added durability. It is also coated with the Silipos® proprietary gel to cushion and protect the below-knee (trans-tibial) residual limb from friction, abrasion and pressure. Constructed with the same great quality as more expensive gel liners, at a fraction of the price. Now available in both 3 and 5 ply versions.
