We present to you, premium medically certified knee protection, natural knee movement, and comfort in one knee brace. Super stiff chassis for maximum control and protection but still comfortable that is the essence of the mono hinge C-Frame Pro Carbon! The C-Frames three-point force distribution greatly reduces forces to the knee, thereby limiting knee injuries (ACL, Meniscus, and MCL) and makes it a vital piece of protective equipment. Lab-tested built-in fracture points make the C-Frame chassis to break before you injure your shin or thigh bone. You will love the super low-profile Carbon shin plate that fits perfectly inside your boots
