DMM DMM Liquid Chalk
The DMM Liquid Chalk is a liquid version of climbing chalk that has been created specifically to last longer and be more resilient than your standard powder, for 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. The application of DMM's liquid chalk is a little disturbing to the uninitiated: a blob of suspicious looking white liquid is rubbed in, and for a moment you are left wondering how on earth you are supposed to cling to the rock with your hands coated in white goo. Then as if by magic, a cold sensation passes through your hands (as the alcohol solvent evaporates) and in a second or two the goo turns to a dry white coating. If any wet bits remain, just spread them around, and they will soon dry up. (It is also much more environmentally friendly, as the trail of white paw marks will be greatly reduced.) Liquid chalk means less time spent re-coating your hands before, on, and between climbs, so you can focus on sending the route.
