The Poly EXP string delivers a crisp feel with added durability, better tension maintenance and 50% less shock.

This string utilises Prince's Co-Extrusion process which creates a livelier response with above average power.

But what is Co-extrusion?

Co-extrusion has been used in synthetic gut for a while now but is new for polyester strings. The majority of polys are manufactured by extruding one material through a single hole to produce the string. Prince have combined nine strands of poly to build the core, then have finished it with a coating of another polyester.

The result is Prince poly EXP, delivering crisp power, excellent tension maintenance and 50% less shock.
