Black Diamond athlete Alex Honnold doesn't rely on much gear, but for all of his climbs, there's one crucial component: chalk. Get your hands on the Honnold-edition Black Diamond Eco Gold chalk.


  • Eco gold chalk is made from pure magnesium carbonate, which is a byproduct of the desalination process, as opposed to being mined from the earth like typical climbing chalk
  • Thanks to its pure form, this chalk is extra absorbent, offering superior drying power and effectively enhancing your grip on tough climbs
  • Sold in a 514 g bag, because that's the climbing grade that Honnold loves most
  • Black Diamond will donate a percentage of proceeds to the Honnold Foundation, whose mission is to promote solar energy for a more equitable world
