The Spy

We took the Incognito core’s great performance and wrapped it in a textured polyester cover, creating a ball that has the length desired from polyester with a little extra kick down lane from the asymmetrical Incognito core. The Spy features a medium RG 2.51 with a strong diff of .053 and a medium intermediate diff of .017.
