When I decided to buy knee protection I didn't want something that looked beyond the relatively pedestrian singletrack rider that I am. Not doing crazy stuff on the trails, but every so often I push it too far and end up with a gravity check. Point being, these pads covered a good 85% of the damage that was likely to happen without, which is what I was looking for. They hardly feel like they are there most times, and rinse dry without losing shape. Good protection for the money.
