DMM Liquid Climbing Chalk

This wonder product solves the issue of keeping your skin coated with chalk on long boulder problems or intense routes were it is impossible, or too strenuous, to take a hand off for a dip in the chalk bag. Rub the liquid onto your hands, the alcohol solvent evaporates, and you are left with chalked hands. The dried layer of chalk is much more resilient to rubbing off than conventional chalk, so you can climb more moves before your skin begins to wet out.

In addition, there are the environmental benefits – use liquid chalk and the normal trail of white paw marks will be greatly reduced.
