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 carabiner 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 you see rock climbers using to keep from losing a grip on their handholds, and many serious disc golfers have been looking for a similar product to help them handle their plastic in all weather conditions.
