The Underlay manages humidity, sweat, heat, and odor inside the socket. Worn under the liner, its open-ended design keeps the liner in contact with the skin to maintain suspension while extending beyond the liner to allow airflow and natural evaporation.

*For more bulbous limbs or added skin contact, the closed version is the ideal alternative.

It’s truly miraculous

I had the chance to try the underlay. The bottom part works really well and helps with heat/sweat when wearing the sleeve. (It’s truly miraculous)

The Underlay offers a secure, comfortable fit that effectively manages sweat, heat, and moisture during intense exercise, helping maintain socket stability without causing irritation or discomfort. Compared to other sweat socks I’ve tried, it significantly reduces issues like slippage, odor, and friction.
