The SuperStroke Flatso™ putter grip features a distinct pentagonal “Flatso” profile: a wide, flat front grip shape with five pronounced edges. Now with Enhanced Spyne™ Technology and Multi-Zone Texturing, the Flatso™ Series has been refined to offer even better feel and feedback. 
The SuperStroke Flatso™ putter grip is one of the most popular grips played on professional tours. PGA TOUR professional Jordan Spieth trusted the Flatso™ grip for each of his three major championship victories.
