Chalk

Chalk in lead climbing and sports climbing refers to a powdered substance, typically made from magnesium carbonate. Climbers use it to keep their hands dry by absorbing sweat, enhancing grip on holds. Chalk is usually stored in a chalk bag, which climbers carry around their waist for easy access during climbs.

Examples

Chalk is a white powder used by lead and sports climbers to improve their grip on holds. Climbers often carry chalk in a small bag attached to their harness. They dip their hands into the bag during a route to reduce sweat and maintain a secure grip. This is especially crucial during challenging sections where a good grip can make the difference between success and a fall.
