Easton Natural Grip Senior Batting Helmet - Men's The Easton Natural Grip Batting Helmet is unique because unlike other one-size helmets, this one comes in specific sizing. No adjusting, no adding or removing pads because the shell sizes themselves are varied. That ensures your helmet fits perfectly for the maximum amount of protection. The high-grade ABS shell brings strength and durability, coated in a rubberized matte finish. Inside, dual-density foam protects comfortably with Bio-Dri™ moisture-management lining. Meets NOCSAE standards. Sz: Hat sizes 6 7/8-7 5/8. Head circumference 21.5"-23.75".
