Tennis String Iso-Speed Professional (12 m)

Tennis string Iso-Speed Professional (12 m)

From the Pre-Stretched string series. These are the first strings that combine the advantages of natural strings – almost constant elasticity throughout the entire period of use, very high playing comfort and maximum arm protection – with the advantages of synthetic strings – durability and resistance to weather conditions. Thanks to the use of a polyolefin blend, a string almost identical to natural gut has been created. Iso-Speed Professional is characterised by maximum ball acceleration and precision. A string for professionals.
