The Leatt C-Frame Pro Carbon Knee Brace offers premium, medically certified knee protection whilst still allowing for natural knee movement and comfort. Although no knee brace can protect one fully from injury, the C-frame Pro Carbon offers a higher level of protection than other traditional ‘cage type’ designs. The brace’s three-point force distribution with super stiff forged C-arm mono hinge construction as well as reduction of forces to limit knee injuries (ACL, Meniscus and MCL), make it a vital piece of protective equipment. It is further equipped with lab-tested, built-in fracture points, and the C-frame chassis protects one by breaking before you injure your shin or thigh bone. The C-Frame Pro also sports a shin bone section with a load distribution plate that is super low-profile.
