Evnroll ZERO Putters represent a new era in putting performance thanks to their zero torque balancing. This design aligns the shaft with the head's center of gravity, virtually eliminating torque and keeping the putter square to the target throughout the stroke. Maintaining a square face at impact is critical to successful putting. Evnroll's data shows that a mere one degree of variation can cause a ten-foot putt to miss, and a scant 0.5 degrees is enough to send a twenty-footer offline. Like all of their models, the ZERO lineup showcases Evnroll'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 Z5 Hatchback is a high MOI, winged mallet featuring distinctive full-body sightlines and precise directional 3D milling that offer effortless alignment. The 38 Tour Spec's counter-balanced design, including a heavier head weight, longer shaft, and longer grip, allows players to grip down and engage the larger muscles, diminishing the hands' involvement in the stroke for added consistency.
