Perpendicular chalk is an excellent prescription for better friction.

The generous 80g refillable chalk ball is perfect for both indoor and outdoor – it is less messy but very grippy!


Perpendicular chalk is a premium high-performance product made from magnesium carbonate sustainably sourced from seawater. The pharmaceutical grade means high purity of magnesium carbonate, which means a cleaner and purer chalk with a better ability to absorb sweat and therefore longer-lasting performance.
