FrictionLabs engineers high performance chalk for rock climbing. Chalk Matters. And they obsess over it. You may have thought, "chalk is chalk"...but we've tested all of the chalk out there and found there's a lot more to the story.
All chalk has Magnesium Carbonate and Calcium Carbonate. Chalk board chalk is Calcium Carbonate, and just like a chalk board, it makes your hands feel slimy when exposed to moisture. Magnesium Carbonate, on the other hand, traps water inside its crystalline structure, leaving your hands feeling dry and ready to crush. Lab tests show FrictionLabs chalk has the most Magnesium Carbonate and least Calcium Carbonate.
