Evnroll putters feature the company's award-winning SweetFace Technology. Consisting of variable-width grooves that are wider in the center and gradually narrow toward the heel and toe, creating a precise V-shape, this patented and groundbreaking technology redirects the ball toward the target on mishits. The grooves' progressive spacing also transfers more energy when the ball is struck away from the sweet spot, ensuring all putts travel the same distance, regardless of where contact occurs. In other words, SweetFace drastically reduces the adverse effects of player error, resulting in more makes and fewer three-putts. The Carlsbad Collection's milled full-face insert is exceptionally lightweight, creating 70 grams of discretionary weight. Evnroll strategically repositions the weight at the base and perimeter of the head to significantly increase MOI, stability, and forgiveness. The M1 is sleek mallet featuring gently curved rear wings and a connected back alignment bar. This putter's short slank neck hosel suits players with a moderate arc in their putting stroke.
