The Rungne Magball Pro combines two chalk formulas in one refillable mesh ball. Magdust Superdry handles moisture absorption while Maglock primes the skin first, so both are working together by the time the sequence gets hard. The mesh construction keeps dust off the wall and out of the air, putting chalk where it belongs: on the fingers. What Our Gearhead(R) Experts Are Saying:"The Maglock in the blend acts as a grip primer before the Magdust Superdry kicks in, so my hands stay dry through long boulder problems instead of just at the start."
