Why we made it

Chalk as it's supposed to be.

If your chalk isn't sustainably sourced then it's time to get a grip!

For a long time we have been on the search for the highest quality natural chalk, that's sourced sustainably. But, finding the best natural chalk wasn't enough, we needed uncompromising sustainable chalk and packaging that's safe to use and absolutely spot on for performance. And so, Techno Chalk was born!

Made from regenerated sea waste our chalk is tested for heavy metal content - it's high performance and a chunky blend of chalk that mixes into nugget sized chunks - perfect for climbing, crossfitting and weightlifting.

Why you'll love it

  • Sustainably made from regenerated sea waste
  • Chunky & funky
  • Not that horrible liquid chalk 🤮
