The Infinite Discs Chalk Ball is a unique grip enhancement tool for disc golfers. Rather than being a bag of beads, dirt, sawdust, or other filler, it features magnesium carbonate grip chalk. The chalk ball comes inside a pouch which keeps the chalk from getting all over your bag and clothes while you carry it around. The pouch has pull-strings to keep it closed tightly and includes a carbiner which you can use to clip the pouch to your backpack, disc bag, belt buckle, etc. When needed, simply remove the chalk ball from the pouch to apply a solid dusting of grip-enhancing chalk to your hands.
This is similar to the stuff that rock climbers using to keep from losing grip on their handholds, and many serious disc golfers prefer this style of product to help them handle their plastic in all weather conditions.
