The STX Cell IV™ lacrosse shoulder pad is part of the number one pad system in the game. The fourth generation of our most versatile shoulder pad, Cell IV™ is built for any playing style. Our proprietary STX GeoFlex II™ technology is lighter and 25% more flexible than the previous version. The breathable protection system allows air to flow through the pad to help keep you cool and dry, while the pre-formed shoulder caps are designed to provide an anatomical fit. Finally, removable bicep pads, adjustable straps, and 7-point mobility stretch zones combine for a custom and secure fit.
