Engineered for a straight, powerful stroke, the Bridgestone e12 Contact Matte Red Golf Balls 12 Pack improve your long game and your short game. Contact Force Dimpling increases the surface area contact between ball and club up to 38% to allow better energy transfer and greater distance. Inside, the polybutadiene core is compressed at 48 for a soft, responsive feel. The suryl cover uses 326 dimples for a longer flight path off the tee, and a nimble spin on the green.
