The Lax Training Head has been engineered to the millimeter to ensure a perfect regulation shaft fit. Built of high density plastics and steel, the Lax Training Head was built with a fortitude designed to handle the most brutal of workouts and ongoing training regiments. Our patented solution to building a great lacrosse training program began years ago as a personal solution to powering top lacrosse players. From there, the design has iterated, over and over, constantly improving in efficiency, weight, strength and fit. All of this painstaking design and re-design has resulted in the best Lacrosse training solution on the market.
