Largest Driver Ever - Designed to the USGA limit dimensions with a 16% larger face than the XLS. A deeper, wider face profile paired with limit dimensions provide Cleveland's largest hitting area ever for ultimate forgiveness and maximum stability. MAX MOI - 24 grams of weight placed in 3 optimized perimeter locations allowing the MOI to approach the USGA limit of 5900. Max MOI generates Full Face Performance, maximizing ball speed and improving accuracy from anywhere on the club face.
