Chaska introduces a unique new shape to the TP Collection. With rounded contours, adjustable sole weights, and three forward sightlines, the design provides exceptional stability and simple alignment features. Combine all this with its Pure Roll® insert and you’ll have everything you need to roll with confidence. PURE ROLL™ INSERT Played by Rory McIlroy, Jason Day and Dustin Johnson, the Pure Roll™ insert combines 45° grooves with a softer polymer to increase topspin and improve forward roll across varying surfaces – helping your ball start and stay on its intended line.
