Wilson Duo Spin Golf Balls Designed for the Control player who wants greenside workability and spin but still prefers soft feel and low driver spin Distance off the tee combined with a favorable soft feel around the green gives DUO the "performance double-take" mantra DUO Spin is associated with the "triple-take" due to a third benefit: enhanced spin for more control on shorter shots into the green Adding an inner mantle increases spin on mid- and short-iron shots and increased resilience for ball velocity and distance The Ionomer cover generates high-lift characteristics on tee shots and long approaches from the fairway
