The STX Cell IV™ lacrosse arm pad is part of the number one pad system in the game. The fourth generation of our most versatile arm 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. Dual straps and silicone tape inside the sleeve help keep the pad in place, while Lycra construction provides excellent comfort and moisture management. The STX Cell IV™ is customizable to match the look of your team's uniform.
