Callaway ERC Soft Triple Track Golf Balls 2021 - Yellow ERC Soft is Callaway's longest golf ball with soft feel, and it’s built for increased control around the green. To create all that distance, Callaway have developed a High Energy Core that promotes maximum speed and total performance from tee-to-green. The ERC Soft features a new Hybrid Cover made with a PARALOID Impact Modifier from Dow. This high performance, multi-material construction promotes high launch and low spin for long distance, along with great feel in a durable offering. Around the green it provides outstanding control, so you can play aggressively on approach shots, and in your short game. The PARALOID allows Callaway to make this ball so fast, and with so much spin. To complete the impressive design, Callaway's High Speed Mantle works with the core and cover to further enhance ball speed and greenside control. Callaway's popular Triple Track alignment utilises Vernier Hyper Acuity to help you choose the right line for better putting accuracy.
