McDavid's patented Hex Pad technology consists of closed cell foam padding bonded to a breathable nylon compression fabric. Hex pads move freely and in synch with an athlete's movements. They are lightweight and tremendously versatile. The compression fabric helps provide warmth and compression to joints and muscles for improved athletic performance and faster muscle recovery. Hex Pads are used by many professional and college players to protect wrists, knees, hips, elbows, arms, back, and chest. Copied by several brands, but never equaled in performance or durability. Hex Pads are machine washable and dryable without shrinkage.
