The Alpinestars Fluid Tech Carbon Knee Brace is a completely new knee brace composed of high performance materials resulting in a super strong, 40% lighter brace. By utilizing the carbon polymer compound to create the brace frame, less material is required which keeps the design streamlined and simple. There is ample room inside the brace, which allows users to utilize the new size adapter system which tailors the fit to each rider. With the S.A.S. you won’t have to worry about knee braces sliding down your shins anymore. By creating a snug, proper fit, the brace will always work at its optimum potential as it was technically designed to do. Furthermore, the X strap system is quick and painless for taking the braces on and off. The Alpinestars Fluid Tech Carbon Knee brace is truly an advanced knee brace due to its weight, size, and protective features. Most riders don’t even realize they’re wearing this brace as it’s so refined. Adaptive to freezing temperatures, the Aplinestars Fluid Tech Carbon Knee Brace is the go to brace for motocross and snow racers alike.
