The new STX Cell 4 arm pads are worn by the elite collegiate middies and D Poles in the nation for the hinge free padding and non slip arm sleeve. These pads haven't changed much since their introduction several years back, but they remain perennial best sellers year in and year out! Many of the elite level middies were switching over to elbow pads and smaller defensive pads but were coming home battered. Many of these guys are switching back as a result.
