Why color

The joke is immature. The mission isn’t.

Bright white chalk can create highly visible marks on natural rock. Cok exists to make rock-conscious color options easier to find, easier to use, and much more fun to handle.

Climb loud. Leave the rock quiet.

The Cok Code

  1. Match the rock where local rules permit.
  2. Use less than you think you need.
  3. Brush your marks.
  4. Respect closures and local regulations.
  5. Don’t be a dick.

The cok Lore

We started Cok because we take visual stewardship seriously, without taking ourselves too seriously.

The name earns attention, while the mission gives climbers a reason to recommend us.

People Who’ve Handled Our Cok

Why is it gray or red?

Rock-matching color options are designed to reduce the visual contrast of bright-white chalk marks on some rock colors.

No chalk rule is universal. Check the current regulations and guidance for the specific climbing area before use. Use chalk sparingly and brush away marks where permitted.
