Liquid Climbing Chalk is great for combating sweaty hands on tough boulder problems or for longer periods of time. Liquid chalks are made using magnesium carbonate mixed with alcohol, water and occasionally drying agents. The alcohol evaporates and dries moisture when exposed to air, leaving your hands with an even layer of chalk. All you need is a small amount with liquid chalk, using too much will mean you’ll need to invest in a good hand moisturizer to keep your hands from getting too dry. Chalk brands include Friction Labs, 8b Plus, Metolius, Tokyo Powder, Reset, Redpoint Friction, Perpendicular, Beal, Black Diamond, Mammut, and Wild Country.
