PERFORMANCE TECHNOLOGIES: Built for defense: The Mark 2D head features a stiff construction and wider face shape designed for harder checks and better ground ball control. Every defensemen in lacrosse needs the tools of the trade. Made for players: Just because you play defense doesn't mean you can't perform on offense. The 29 sidewall holes, higher side profile, and slightly pinched throat of the Mark 2D gives you a pocket you can actually play with. Stiffer is better: We used advanced software to make the Mark 2D stiffer and stronger in all the right places. By identifying high-impact areas, we used material more efficiently to create a tougher head that won't weigh you down. Better for ground balls: Everyone knows ground balls win games. Attack the ball from any angle knowing your head was engineered to give you every advantage possible. ADDITIONAL SPECS: 6-month warranty: Visit stringking.com/warranty for more information.
