About Impartial XS
Impartial XS uses pre-tensioned tensor sponge with a catapult effect and relatively low dwell and a pips-out topsheet. Manufacturer sponge hardness is 40° (Tensor); a cut sheet is about 44 g. Factory sponge thicknesses: 1.8, 1.9, 2.0, 2.1, MAX. Sold with topsheet in Black and Red; sponge in cream.
On the TableTennisReview 0–100 index the Combined figures are speed 88, spin 62 and control 80 (official mapping 87 / 62 / 79). That is a mid-to-high speed short pips profile for offensive close-to-table and mid-distance topspin. Hardness, weight and thickness above are factory facts — not lab tests.
Community score 8.6 / 10 from 310 reviews. Indicative European street price €42. Compare Impartial XS with other Butterfly Impartial and short pips rubbers on the same scale, or open the catalogue filters for OFF short pips sheets.

- 1.8
- Short-pips attacking sponge, or a thick anti. Not the same job as inverted 1.8.
- 1.9
- Short-pips mid-thick sponge. Blocks and hits; still not an inverted loop sheet.
- 2.0
- Thick short-pips sponge. More speed on a hit, less of the classic short-pip deadness.
- 2.1
- The thick short-pips option when the sheet is sold that way. Still a pips-out job.
- MAX
- Thickest short-pips sponge the factory lists. Catapult of a tensor, geometry of pips — not inverted MAX.
