The STX Shield is the new big brother to the best selling STX Eclipse. Our Pros noticed the increase in stiffness right away. If you are stopping cannons this head can stand up to the punishment. The next big benefit was the ergonomic hand positioning on the throat design. For advanced goalies that play with the upper palm right at the base of the head - there is no better option. The angle of the top rail allows for the same easy clearing ability as the Eclipse. Overall, this is a upgrade for advanced goalies but we still see the Eclipse as the go to for advanced youth players.
