Name: Ethnocare Underlay TT Open Sweat Management Sleeve
Brand: Ethnocare
SKU: ET0112
Price: 30.0 USD

The Ethnocare Underlay TT Open is a transtibial sweat-management sleeve designed to help control humidity, perspiration, heat and odour inside a below-knee prosthetic socket.

Worn under the prosthetic liner, the Underlay uses a proprietary moisture-management knit to help move sweat away from the residual limb and improve comfort during everyday wear, exercise and hot-weather conditions. Its open-ended design allows the liner to remain in direct contact with the skin where required for suspension, while the Underlay extends beyond the liner to encourage airflow and natural evaporation.

Ideal for Hot Climates and Active Users

Sweat accumulation inside a prosthetic liner can affect comfort, suspension and skin condition, particularly during exercise, long working days or in warm environments. The Ethnocare Underlay TT Open provides a simple way to manage this moisture without changing the prosthetic socket or suspension system.

For prosthetic users in regions such as the Middle East, Africa and South Asia, where high temperatures and humidity can make perspiration a significant daily challenge, the Underlay offers a practical addition to the prosthetic interface that can help make extended prosthesis use more comfortable and manageable.
