Abstract: A pair of leg guards for sports, particularly of the type worn by hockey players under elastic socks, each includes rigid plastic shin and knee guard sections. A thigh guard section is joined continuously to the knee guard section. The shin guard section has front and rear panels. A channel is molded preferably diagonally across the front panel in which a rigid plastic strap protector is affixed. The strap protector has a slot through which a one-piece elastic strap passes to detachably secure the guard to the wearer's leg. The one-piece elastic strap has horizontal and diagonal strap portions which wrap around the back of the knee and lower leg respectively of the wearer and connect to the shin guard section by hook and loop connectors. The rear panel and the inside of the knee guard section are fitted and affixed continuously with a detachable liner for further protection of the wearer's leg and to enhance the life of the guard.
