The Pro Hard Shell Knee Guard offers Sweet Protection's top level of protection for downhill riding--all without compromising on pedal friendliness. On rowdy trails, these guards help protect our knees with additional pads on each side and a hard-shell in front for low-friction performance. The double-fit adjustment system works with the interior gripper elastic for a locked-in fit all ride long, while the highly breathable, stretchy materials ensure well-ventilated, flexible comfort.
