The WillowWood Alpha® SmartTemp® Liner is a prosthetic liner designed for transfemoral (above-knee or AK) amputees. It integrates advanced temperature-regulation technology to manage heat and reduce perspiration inside the socket.

This revolutionary prosthetic liner absorbs heat as it builds up in the residual limb, then releases the stored heat as the body cools down. Select fabric allows circumferential stretch while controlling pistoning without a distal matrix. The Alpha SmartTemp Prosthetic Liner retrofits with any Alpha Liner with a progressive profile.

• Heat Management: Uses Phase Change Materials (PCMs) originally developed by NASA (Outlast® technology) to absorb, store, and release body heat.
• Sweat Reduction: Delays the onset of sweat and reduces overall perspiration.
• Select Fabric Cover: Features a specialized outer fabric that minimizes distal pistoning (sliding up and down in the socket) while still allowing circumferential stretch for easy donning.
• Suspension Options: Available in locking or cushion configurations, tailored for above-knee symmetrical profiles.
