Thermoplastic polyurethane, also known as TPU, is a class of plastics with many useful properties. Its high tear strength, and exellent cold weather flexibility, make TPU a very good choice of material to build zorbing balls. TPU is more abrasion resistant than PVC and is generally longer lasting. The drawback is the price. TPU is much more expensive than PVC. Each zorbing ball comes with a suitable blower, repair kit, and free shipping to lower 48. The colors of the handles and harnesses may vary unless a color is requested.
