Knee pads for hockey goalies are not a required piece of protection, but will add additional cushion to the goalie's knees, which are hitting the ice with regularity during a game. These generally attach with velcro strapping and are worn under the
leg pads and often tuck under the goalie pants. The leg pads do most of the work for you, but if you're looking for just
a little bit more protection at the top of your knee, these are a good investment.
