Play with the pucks the pros use. Measuring 3" in diameter, 1" thick, and weighing 166 grams, these ice hockey pucks are NHL-official. And, made from solid vulcanized rubber and manufactured to exacting standards of hardness and surface flatness, these pucks can stand up to NHL-official use and punishment. So dont settle for less: for softer, less smooth pucks. Choose Crown Sporting Goods and shoot harder, pass faster and more accurately, deke like Kane, and dangle like Datsyuk.
