The Arc'teryx C80 Chalk Bag is a large chalk bag for people with bigger hands. If your paws are giant, then give the C40 to your tiny handed friend and go with the C80 for yourself. The larger opening won't cause your hand to get trapped inside with all the chalk, leaving you hanging one-handed on the wall. Since this one is bigger, Arc'teryx found room to fit an external zipper pocket on the bag, where you should definitely put a bunch of candy inside. When packing up, pull the drawcord tight so chalk won't escape on the way home.
So sorry, but only 4 items are allowed for comparison. I blame the gnomes and so should you.
