The almostGOLF ball is perfectly balanced for true spin, trajectory and accuracy. Its unique cross-linked foaming and internal pressure results in a .32 COR rating, approximately one third of a traditional golf ball. As a result, the almostGOLF ball compresses slightly upon impact just like a real golf ball, giving it real 'pop' off the club face and long-lasting durability. But because of its special core construction, the almostGOLF ball is extremely soft, making it backyard safe.
