A 3/32" over-sized version of the popular Tour Pro perforated provides outstanding feel and control in an over-sized grip. Available in core sizes: .580 or .600 Weight: 67 grams (+/- 2 grams). Latex Free! They are 10 1/4" in length prior to putting them on shafts.
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.
