We received one of the Kettleballz from John Rarity last week. We put it to use at our gym right away. Filled it up with play sand and it was ready for a workout. We love that it is portable and we can throw it in a ruck sack and hike down to the river for a workout. Fill it up with rock, sand, gravel, mud – makes no difference as this bag can handle it all. Washes out easy and ready to go again. Good job John, we look forward to using Kettleballz at the CrossFit Grinder.
