About Bluestorm Z2
Bluestorm Z2 uses pre-tensioned tensor sponge with a catapult effect and relatively low dwell and a grippy, non-tacky topsheet typical of European tensors. Manufacturer sponge hardness is 47° (Tensor); a cut sheet is about 47 g. Factory sponge thicknesses: 1.8, 1.9, 2.0, 2.1, MAX. Sold with topsheet in Black and Blue and Red; sponge in blue. Bluestorm is a later Donic Formula generation (Z1/Z2/Z3) with a slightly livelier sponge than Bluefire.
On the TableTennisReview 0–100 index the Combined figures are speed 92, spin 88 and control 80 (official mapping 91 / 87 / 80). That is a high-speed inverted profile for offensive close-to-table and mid-distance topspin. Hardness, weight and thickness above are factory facts — not lab tests.
Community score 8.5 / 10 from 140 reviews. Indicative European street price €38. Compare Bluestorm Z2 with other Donic Bluestorm and inverted rubbers on the same scale, or open the catalogue filters for OFF inverted sheets.

Factory thicknesses
Factory sponge thicknesses sold in Europe: 1.8, 1.9, 2.0, 2.1, MAX. These are shopping facts — Combined speed / spin / control on this page do not change with thickness.
- 1.8
- 1.9
- 2.0
- 2.1
- MAX
- 1.8
- Thinner inverted sponge. Allround and first-upgrade backhands live here more often than attacking forehands.
- 1.9
- The usual club backhand thickness on inverted tensors. A bit more control, a bit less catapult than 2.1 / MAX.
- 2.0
- Mid-thick. Common on the backhand when MAX felt lively, or as a two-wing compromise.
- 2.1
- Still a thick attacking sponge. A small step down from MAX on some tensors — shops treat it as the other FH thickness, not a control sheet.
- MAX
- Thickest factory sponge. Most catapult on a tensor; the usual attacking forehand. Combined figures on this page are for the SKU, not a separate MAX score.
