Performance Chalk (200g), magnésie avec Upsalite

KletterRetter's Performance Chalk represents the next generation of magnesium carbonate – developed by climbers, for climbers. The formula combines high-quality, ultra-pure magnesium carbonate with 10% Upsalite®, an innovative, highly porous form of magnesium carbonate that binds moisture, sweat and oils significantly better than conventional chalk.

The result:
More friction, longer-lasting dry hands and noticeably more consistent grip – even during intense sessions and changing conditions.

Why 10% Upsalite?
Upsalite can absorb up to 10 times more moisture than classic magnesium carbonate. But pure Upsalite would dry the skin too strongly and would be extremely expensive. The blend of 90% MgCO₃ and 10% Upsalite provides the optimal balance between maximum performance and skin-friendliness.
More performance – without unnecessarily drying out the skin.
