SPRI Chalk Ball is great for gymnastics, rock climbing, weightlifting and high intensity workouts, giving you the grip needed to excel and push to greater heights! It's basically a chalk block in a bag, get all the dry hands benefits from a traditional chalk block, but without all the crumbly mess. Premium-grade pure, non-toxic magnesium carbonate is packed inside a cotton sock, and tightly secured so chalk will not spill out of the top. With just a few quick squeezes the chalk will absorb and eliminate moisture to keep sweaty hands dry and does not easily rub off so you can lift or climb longer with confidence. Chalk ball can easily fit in a chalk bag, pocket, or strapped to a belt for easy access and a quick squeeze is never too far away - can be used as a personal bag or shared with the group. Chalk helps to keep hands dry, and prevent blisters and calluses while reducing slippage during your workout - sold as a 2 pack so you can keep one at home and one in your gym bag.
