ISO (Isometric Square Head Shape)
This exclusive Yonex innovation results in a sweet spot up to 48% larger than a traditional oval head shape. According to Yonex, it ensures more power and control with fewer off-center shots.
Different from conventional synthetic resin which stacks carbon fibre against each other, the new resin; Toughlex has more flexibility and it durability.
Inserting the Toughlex into the whole racquet frame creates a more powerful shot. As a result, players can make a stronger spin shot with longer ball dwell time.
