KletterRetter Performance Chalk is 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, grease and oil significantly better than conventional chalk.

The result: more friction, longer dry hands and noticeably consistent grip, even during intense sessions and changing conditions. Ideal for performance climbers and competitive athletes who need maximum precision and grip.

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

Features:
• 10% Upsalite for superior moisture absorption
• Skin-friendly, allergen-free, no resins or fragrances
• Reduced consumption thanks to higher efficiency
• Cleaner chalk experience with less dust
• Food grade, dermatologically tested
• 100% recyclable mono-material packaging (made from 30% recycled material)

Application:
As usual, take a small amount, distribute evenly, tap off excess chalk and reapply lightly if necessary. Due to its high efficiency, less chalk is often needed than with standard products.
