Soft neoprene pellets fill this unique ball that has a combination of fabric and mesh that creates a parachute effect which slows the flight of the ball. Perfect for early development in learning to throw and especially catch with no fear. Excellent for teaching palms up method of juggling (as opposed to palms down or clawing technique needed when juggling scarves). Also a great product for learning striking (including kicking/footbag or use with a racquet/paddle), balancing, pain free dodge ball, and an endless number of other fun activities. Originally designed for use in adapted PE and still one of the best products in this field!
