Product Description
Natural Bamboo Charcoal Fibers Combined with Aerocool Technology for Premium Joint Support and Odor Control
The Star Sports Bamboo Charcoal Knee Support XD341W is an advanced orthopedic sleeve designed for superior joint stability and skin comfort. Featuring a specialized blend of Bamboo Charcoal fibers and Aerocool yarn, this support guard naturally absorbs odors and wicks away moisture at an accelerated rate, keeping your knee dry and fresh during intense activities. The computerized weaving provides targeted compression on muscles while maintaining high breathability in flexion zones. Its 3D ergonomic pattern ensures a snug, non-slip fit that mimics the natural movement of the human knee. By distributing pressure evenly, it prevents injuries and maintains therapeutic warmth to improve circulation, making it an essential tool for both sports performance and injury rehabilitation.

- 3D Ergonomic Non-Slip Pattern
