WHAT IS ROCK CLIMBING CHALK?
Chalk is mined as Dolomite, a mixture of Magnesium Carbonate, Calcium Carbonate, and numerous other compounds.
HOW THIS IMPACTS YOUR GRIP
The difference is on your hands.
More Magnesium Carbonate = Drier Hands = Better Performance
All climbing chalks market themselves as Magnesium Carbonate, because that's what dries moisture the best. They mislead you in to thinking it's only Magnesium Carbonate when the truth is that they all have significant amounts of Calcium Carbonate and other fillers. Calcium Carbonate - the same stuff as chalk board chalk - just gets slimy when mixed with moisture. When you sweat, keeping your hands dry depends on having chalk that has high amounts of Magnesium Carbonate and low amounts of Calcium Carbonate. We had an independent lab test our chalk against the most popular options to see what they're made of.
The results are clear: FrictionLabs has the best chalk for rock climbing! See the data for yourself!
