For riders who need stability and protection for their knees, the 6400 knee brace offers support in a lightweight and comfortable package. The bilateral support hinges of the 6400 knee brace use hyperextension stops to support the knee and prevent injuries. Comfort is ensured by the X-Fit Strap System, which prevents pinching that could restrict movement and cause discomfort while on the trail or slopes. The adjustment of the upper and lower compression straps allows for a personalized fit. The protective thermoplastic knee pad is covered with an abrasion-resistant material that ensures ultimate durability and longevity. All of this is contained in a lightweight knee support that feels at home on a mountain bike, motorcycle, snowboard, or skis.
