Overview

Developed for Daniil Medvedev, who wanted more power and pocketing than Razor Code. Constructed with the same high-modulus polyester but with a unique polyurethane additive melted into the core. Despite the name "Razor SOFT," this is not a soft string - it offers more pocketing than Razor Code while maintaining excellent control. A firm but not harsh string with excellent control on full swings. Outstanding playability duration - a well-known weakness of co-poly monofilaments. Medvedev has had his best seasons since switching to Razor Soft.

Best For

  • ✓ Intermediate to advanced players wanting control with pocketing
  • ✓ Players who find Razor Code too firm
  • ✓ Those who like Yonex Poly Tour Pro or Head Lynx Tour
  • ✓ Players with rackets over 300g

Not Ideal For

  • ✗ Maximum spin seekers
  • ✗ Beginners
  • ✗ Light rackets under 300g

Pros

  • + Developed for Medvedev - proven at top level

  • + Good tension maintenance
