The K4 3.0 knee brace is designed to provide a natural, secure fit with substantial knee-impact protection for riders and multi-sport athletes. Built around Human Motion® technology, it uses a low-profile, lightweight Impact Modified Frame and adaptive cuffs intended to move with the leg throughout a full range of motion. The Human Motion® hinge is designed to support smooth movement while helping guide forces away from the knee ligaments. Reinforced hinge components, an integrated knee-capture system, snap-in hinge pads, and strengthened ligaments are intended to deliver dependable performance with reduced maintenance needs.
Full-coverage impact guards provide protection while allowing airflow for comfort, and can be removed for use across other sports. FLEX Grip Frame Liners are bonded directly to the brace frame to help minimise brace movement and bulk; their non-absorbent construction resists sweat and moisture. Fit can be tailored through adjustable extension control, allowing a preferred extension limit between 10° and 20°, plus thin installed hinge pads and included thicker pads. Progressive extension control is designed to slow the joint before full extension, helping reduce abrupt lockout forces.
