Product Description
Enhanced Impact Protection with Ergonomic Embossed Padding and Breathable Cotton Comfort
The Star Sports Cushion Knee Support XD321W-03M is a high-performance protective gear designed for sports that involve frequent knee contact or impact, such as volleyball, dance, and indoor fitness. Featuring an ergonomic embossed cushion design, it provides comprehensive coverage for both the front and sides of the knee, ensuring a secure and stable fit. The core is constructed with resilient PU sponge foam, which effectively absorbs high-velocity shocks to prevent bruising and joint injuries. Crafted from a premium cotton-blend woven fabric, this support offers superior breathability and moisture absorption, keeping your skin dry and comfortable during intense matches. The high-elasticity weaving pattern provides optimal compression, supporting the surrounding muscles to enhance your mobility and power on the court.
