Riding with your knees to the breeze brings unease: for everything but the mellowest pedals, knee protection has become compulsory. Leatt s 3DF 5.0 Knee Guards are certified bomber, designed to cushion your knee from impacts on front and sides. A good pad for heavier riding, they're still comfortable and pliable enough to pedal in. Don't get caught pulling rocks out of your skin for the next month, invest in a good pair of knee pads!
