Reebok's 16K hockey pants are constructed for durability with the use of 440D nylon with key stretch areas providing a streamlined front and comfort, plus ventilation to maintain dryness. JDP hip caps protect by dispersing the energy of impacts away from the fragile joints. Molded PE kidney protection conforms to the body for gap-less protection. The floating spine protector follows the body movement to protect the lower spine. Segmented foam with molded PE inserts for the lower back allow for mobility without sacrificing protection. Foam thigh guards provide great slash protection. This pant offers an easy to use hidden length adjusting zipper under the padded belt which allows for up to one inch in length for growing players.
