WArrior-Evo 4 ECD Mesh Re-engineered for the perfect balance of lightweight stiffness, feel and consistent release. The New SymRail design interior sidewall mirrors the outer for reduced weight without sacrificing stiffness. Maximum string holes for customized pocket placement. The newest version of the Warrior Evolution is lighter, stronger and has added stringing options for any pocket style. If you are a player who has a very specific way you want to carry and shoot the ball, the new Evolution 4 lacrosse head will allow you the most custom pocket options possible. The sidewall hole placements are designed for any type of pocket, yet the new design dripped the weight and increased the strength. Strung with ECD Vortex or Hero Mesh.
