Friction Labs is one of the premium brands that explicitly make chalk for climbers. Very popular in the gym, Friction Labs products consistently score high in customer reviews for all their traditional and liquid chalks. Besides the great friction it offers, Secret Stuff liquid chalk tends to be more skin-friendly than other products. Friction Labs even offers an alcohol-free liquid formula.
