Our latest cover has been pimped to provide a heavier duty and superior cover to better withstand punctures by sharp objects. We only now have maroon and Black left All seams on the new cover design are now double stitched and the 1000 denier cordura cover has a PVC backing making it very strong. We have tested this cover by leaving it in the open in our arena for the previous summer and this entire winter and it remains in top condition. The cover is designed to be used with the Free rein exercise ball and when inflated stands 100 cm high (measured vertically from a flat surface). The cover has our usual features including the easy to carry handle hidden under the flap closure and quality zip. Unfortunately we no longer have any stock of our inner balls and not certain with the covid issues and importing whether we will bring more in. Other brand inner balls can be used with our cover as long as they are the correct size inner ball. Other brands of inner balls unfortunately do not have the same heavy gauge of rubber used by Freerein but should still provide reasonable longevity if used with our cover.
