Donic Bluestorm Z1: A Lightning Strike!

Bluestorm Z1 with its medium pored sponge and a short, wide pimple structure is the hardest and fastest of the three Bluestorm versions. It has immense power. However, in order to engage with so much horse power, a competent driver is required behind the wheel. A well trained player, master of the fastest game, will find Z1 to be a lethal weapon.

And topspin with this rubber are quick as lightning!

Bluestorm: A comprehensively thinner top surface rubber, subjected to high tension, allows space for a thicker sponge - generating extra power and speed. The Donic Bluestorm Series offers noticeably greater acceleration while retaining its outstanding spin and speed characteristics, making the latest trend. The thinnest sponge is 1.9 mm, middle sponge thickness is 2.1 mm - and the thickest variation is called max+, because this sponge is even thicker than previous max versions. Bluestorm is available in three versions. Select your own Bluestorm!
