The unique serrated design and soft compound gives outstanding control and feel for anyone looking for a 3/32" over-sized grip. Core size: .580 or .600. Weight: 65 grams (+/- 2 grams). Latex Free!  

The core size is the "opening in the grip" where the shaft goes into. Example: if the core size of .580 the opening is smaller than .600 which will make the wall "thickness" slightly larger and the grip will feel bigger vs a .600 core size grip on the same shaft.
