The SPRI® Ultraball® has superior performance and maximum durability which help make it the safest and most reliable stability ball on the market today. It's made of a heavier, thicker-gauge material than other balls, so it's more resistant to stretching or deforming and ideal for use in the most demanding club environments. The dimpled surface offers a 360 degree body-traction effect. Slow-deflate anti-burst technology up to 600 lbs. Available in 65cm. Includes a free downloadable exercise guide.
