The Reebok 18K hockey pant is an elite-level pant in Reebok's 2013 line of protective equipment. It is a continuation of the 20k line, encompassing multiple characteristics of that pro-level pant. The nylon has certain stretch areas that make for more comfortable movement. The JDP hip caps intend to redirect any direct impact away from the hip joint. This pant also has all the necessary protection in the waist and lower back area as our Tech Description outlines. Possibly the most useful feature of this pant is the hidden zipper that will allow for up to an inch of extension so have no worries if you or your hockey player is growing!
