Alpha Duo® Liner

The fabricless Alpha Duo Liner combines the comfort of gel with the durability of silicone. Alpha Classic gel lines the interior, providing all-day comfort with skin-protecting mineral oils and vitamin E. Alpha Silicone covers the exterior, providing durability and protection with a satin finish for easy donning.

A One Gel Sock is included with each Alpha Duo Liner, which aids liner longevity and provides an air wick for optimal suction and vacuum suspension. Designed for transfemoral use, the Duo Liner may be used as part of a passive or active system.
