The sand-filled rang footbags are designed for stability and versatility in body stalls. The sand filling inside the footbag helps it to "splat" on landing, which makes it more stable and less likely to roll away. The number of panels on the footbag affects its performance - fewer panels result in a larger splat and greater stability, while more panels result in greater accuracy and a higher rebound. It's worth noting that the colours of the footbags may vary from those shown, so customers may receive a footbag in a different colour than what they saw in the product photos.. Sold individually
