Knee Pads… Theses things are awesome, they are pretty much the only thing that will actively work on keeping you from getting road rash. During a fall you can reliably fall to your knees knowing that you will have a safe pad to crash with. The KP 22 knee pad has multiple fitting straps to keep your knee pad in place during a tumble, and the soft interior foam will help to prevent bruising and hard impacts to the knee, while the plastic shell of the pad will minimize the road rash that will take place on your skin.
Knee Pads, dont leave home with out them.
