Black Diamond Eco Gold Rock Climbing Chalk

About the Black Diamond Eco Gold

Black Diamond’s Eco Gold Chalk is made from environmentally friendly, pure, and extra absorbent magnesium carbonate.

Because magnesium carbonate is the byproduct of the desalination process rather than being mined from the earth like most climbing chalk, it is extremely kind to the planet. Magnesium carbonate is also very absorbent and offers superior drying power, as well as enhancing your grip.

This edition of Black Diamond’s Eco Gold chalk is made in partnership with Alex Honnold and specifically the Honnold Foundation, which supports solar energy for a more equitable world. A percentage of sales for every bag goes to the foundation.
