Got my son a hoodie and knee pads for his 5th birthday after a couple of spills on the pump track. These things are incredible, used daily for about 5 months now and still show no signs of wear, he's rolled over in them, slid down the concrete walls of bowls in them and they just dust off. Most importantly they give him the confidence to try new things without being distracted by the fear of falling. I will continue to move up in sizes for a good few years yet. Really cannot recommend them enough.
