For the rider needing stability and protection for their knees, the 6400 Knee Brace offers protection in a lightweight and comfortable package. The 6400 Knee Brace‘s bilateral support hinges use hyperextension stops to support and help prevent injury to the knee. Comfort comes from the X-Fit Stap System that helps prevent the bunching that could limit movement and create discomfort while out on the trail or slope. Adjustment Upper and lower compression straps to create a customized fit. The protective thermoplastic knee pad is covered in an abrasion-resistant material for ultimate durability and longevity. All of this is on a lightweight knee brace that is at home on a motorcycle, mountain bike, snowboard or skis.  No package.  I I opened  these up and put them in my gear bag excited to use them .  When I got to the trail I  tried on to put them on to  find out my legs are to big for them. So they have not been  used.
