Tour Edge Men's Exotics Trilogy Hybrid The Trilogys unique sole design features two outer rails and one inner rail that help players hit perfect shots from any lie. The outer rails move more mass to the rear heel and toe, producing a higher moment of inertia for enhanced stability on off-center hits. The inner diamond rail performs as a rudder, guiding the clubface into a square position at impact while minimizing divots for easier-to-hit shots. The Trilogy features a 60gm internal weight pad that lowers the center of gravity for more forgiving shots that get up and away quickly and easily. Experience the performance of the Trilogy and discover refined power and sensation of remarkable control. Lifetime warranty and 30-day play guarantee.
