DONIC BLUESTORM - A storm brews! BLUE ALERT 

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 outstanding spin and speed characteristics, making this rubber especially well suited for the new plastic ball. The thinnest sponge is 1.9 mm, middle 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, Z3, Z2, and this version, Z1.

DONIC Bluestorm Z1: A LIGHTNING STRIKE 

Z1 with its medium pored sponge and 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 horsepower, a competent driver is required behind the wheel. The well trained player, master of the fastest game, will find Z1 to be a lethal weapon. 

Topspins with this rubber are quick as lightning!
