Crux Original Liquid Chalk is a dense, deep-drying liquid chalk built for hot, sweaty and humid sessions. It lays down a thick layer that soaks up sweat and keeps drying, so it's our pick for warm climates, humid crags or hands that sweat more than most.

It's formulated with pharmaceutical-grade magnesium carbonate and an ethanol base that's gentler on skin than isopropanol, drying fast with a lighter smell. Rosin-free and low-dust, it's kind to holds and gym flooring alike. Formulated and manufactured in Crux's own lab in Spain, in a 200ml bottle.
