FrictionLabs Secret Stuff Chalk Cream
That slippery grip? Chalk it up to sweaty hands. To rain and humidity. To oily sunscreen. Then chalk it up from finger to wrist to fix it. FrictionLabs says their Secret Stuff Chalk Cream is the best liquid chalk on the sidewalk for overcoming grip problems. In addition, the Colorado-made salve contains no artificial drying agents like Silica so it won't "trash your skin" at the same time it's de-slicking it.
Despite its name, Secret Stuff Chalk Cream is happy to share its ingredient list: isopropyl alcohol; non-toxic, pigment-free magnesium carbonate; and water. The cream is safe for both kids and adults, and recommended for athletic activities ranging from rock climbing and gymnastics to hangboard training and CrossFit.
During use FrictionLabs says their Secret Stuff also naturally cleanses and disinfects hand. Each bottle should give you at least 100 uses.
