Familiarity: I've put it through the wringer
Love the bag! I specifically wanted one that wouldnt spill chalk all over the place while I have it riding in my climbing bag. This one has a pull tie, and a zipper, so its always clean! Its big and holds a lot of chalk as well!
It is a little light though and easy to knock over when upright.... so if youre one to through your bag around when bouldering you may spill chalk every once in a while. (Sorry to my local gym for chalk spills all over). Its no fault of the bag though, just forgetful user in the zone.
