STX Cell V Lacrosse Arm Pads are hugely popular with elite/collegiate midfielders because of their hinge free padding and non slip arm sleeve. Although they haven't changed much since they were first put on the market, the beauty is that they were designed dang near perfect as is, so they continue to be a best seller. These offer high protection and equally high mobility, which is vital when you are a middie who doesn't like to stand back and watch the action. And the new Dual 360+ straps will keep them in place on your arms.
