The Traxion FLATSO 3.0 features a patented no taper technology that creates even grip pressure with a uniform profile that helps maintain the head path for a more consistent stroke. Traxion Control enhanced feedback zones use a tacky polyurethane outer layer for comfortable feel and enhanced feedback. The Advanced Spyne Technology helps create repeatable hand placement and keeps the putter face square at impact. The Tech-Port on top of the grip is designed to be used with all Superstroke’s Tech-Port accessories including the CounterCore weight system (weights sold separately). Flatso grips are designed with a pentagon shape. The Flatso 3.0 grip weighs 64 grams.
