Make sure you punt off the heinous whipper you're about to take off your climbing project so photographers can only see white chalk exploding out of Edelrid's Rocket Twist Chalk Bag, because you don't want any photos until the glorious redpoint. Its unique closure ensures a dustproof seal, but since you have the bag opened while you climb, all that chalk is going to fly. There's an attachment loop, webbing belt, and brush holder for extra convenience.
