The world's most trusted knee brace has evolved.
The K4 3.0 is designed to move with you, delivering a natural fit and a high level of protection when it matters most. Featuring Human Motion® technology, it has been refined through years of testing and real-world use.
Impact Modified Frame
The Impact Modified Frame combines strength, light weight and a low-profile design, while the Adaptive cuffs follow the movement of your leg for all-day comfort, whatever the terrain.
Full impact protection
Designed to provide full impact protection while ensuring excellent ventilation for maximum comfort.
The guards can be removed quickly, making the K4 3.0 suitable for multi-sport use too.
Human Motion® hinge
Designed to work in harmony with the body's natural movement, the Human Motion® hinge helps divert forces away from the ligaments, ensuring smooth, natural movement throughout the full range of motion.
With reinforced linkages, a reinforced hinge housing, an integrated knee containment system and quick-fit hinge inserts, the K4 3.0 is built for reliable performance and low maintenance.
FLEX Grip Frame Liners
Attached directly to the frame, the FLEX Grip Liners help keep the brace securely in place, reducing movement and bulk and keeping maintenance to a minimum.
The non-absorbent material resists sweat and moisture, keeping the brace fresh, comfortable and odour-free, ride after ride.
Customise your fit
Extension adjustment
Set your preferred extension limit between 10° and 20° to suit your riding style.
- The progressive extension control system helps cushion the end of travel, slowing the joint before it reaches full extension and reducing harsh impacts on the knee.
- Hinge Pads: The brace comes with thin hinge pads pre-installed and a set of thicker pads included in the owner's kit, so you can tailor the fit to your needs.
- Multi-sport ready: From track to trail, water to snow, the K4 3.0 adapts to you. The removable impact guards let you switch from one sport to another in minutes.
