Dip your hand into Petzl's Sakapoche Chalkbag before a palm-sweating crux on the climb. The Sakapoche is like most chalkbags, in that it hold carbon magnesium to dry up your sweaty hands, except that it also has a pocket to store topo maps, keys, or even Petzl's small e+Lite headlamp for improved versatility. Petzl added a toothbrush holder so you can scrub off the crux hold until you can actually pull on the sucker.
