The most comfortable brace ever designed. Lightweight, glass-filled nylon shell conforms to your leg shape creating 360 degrees of protection that won't rotate or slip. The Continuous Cable Routing System (CCRS) adjusts the fit with a simple turn of the locking composite dial; the Figure-8 cable and behind-the-knee adjustment pad greatly strengthen the joint, yet work as freely as your body's own ligament system. Overlapping patella area with adjustable, composite extension stops leave no gap exposed regardless of how far the knee is bent.
