This is some pretty awesome chalk. I got it from the gym that I go to a few weeks ago, except in the form of a ball. I used to have to stick my hands in my bag like every fifth move, but I can now go up a whole route without chalking more than five times total. As far as I can tell, the ball the chalk comes in is durable, unlike many other balls that I used. Also, I like that there are no added chemicals in it. This helps your hands by avoiding torture and the same with the environment.
