Troy Lee Designs youth elbow guards feature an ergonomic design that's properly proportioned to their size for a better fit and protection. They feature a polycarbonate shell and ventilated foam backing to absorb impacts to the parts of the body most likely to take a hit: your youngster's elbow and forearm--no more bloody arms and elbows! Plus, the Velcro® straps on these youth elbow guards will keep the pads comfortably in place at all times.
