Developed over several years of relentless testing, Mach 10 was originally known as 10jx and Confidential 4.0. It is Solinco's most technologically advanced string to date. The secret sauce is called CloudFORM, a unique chemical agent that softens the string without the usual tradeoffs in playability duration. With five sharp edges for enhanced bite and a low-friction surface for vicious snapback, Mach 10 is built for spin. Factor in the higher power level, and you get a heavy ball that drops hard and explodes off the court.
