Our most durable stability ball! Made of heavier, thicker-gauged PVC material with an updated, dimpled surface - this ball is more resistant to puncture, deformity, or losing shape. Ideal for heavy traffic and commercial use facilities. The smooth, slightly dimpled surface offers a full 360-degree range of use, no raised surfaces to impede comfort when rolling your body on it. Easy to inflate, and includes a tape measure make it easy to tell when you've added the right amount of air. Black. Two sizes available, diameter clearly marked. Sold individually. Storage options and pumps available. Pump not included.

Pro Tip: On first inflation fill to 75% of capacity and stop. After a few hours you can fill to the desired level. The thick PVC needs time to adjust, but this features is what helps keep it burst resistant.
