2021 Callaway ERC Soft Triple Track Golf BallsThis is our longest golf ball with soft feel, and it features an innovative new Hybrid Cover, with a PARALOID Impact Modifier from Dow*. Thats how ERC Soft delivers an incredible combination of maximized distance from high launch and low spin, soft feel, durability, excellent greenside control, and advanced alignment with Triple Track Technology. Maximum Ball Speed and Total Performance From Tee-To-Green - High Energy Core is engineered to increase ball speed and distance through the bag. The core also works with the High Speed Mantle to boost resilience and speed. Advanced Alignment From Triple Track Technology - Weve prominently featured Triple Track lines on the ball for improved putting accuracy. Triple Track uses Vernier Visual Acuity to improve alignment compared to a regular side stamp alignment aid. Enhanced Ball Speed and Control - Our High Speed Mantle creates more efficient energy transfer between the layers for more ball speed, and provides more wedge spin around the green. Advanced Alignment From Triple Track Technology - Weve prominently featured our popular Triple Track lines on ERC Soft to help you focus and find the right alignment for every putt.
