Every coach should have wind balls for training purposes. JASPO wind balls are made with great quality PVC rubber and are heavy enough to be able to throw a good distance, though they are not as heavy as a leather ball and thereby, ideal for practice sessions. The Jaspo Wind ball can also be used to produce different trajectories through the air, with different techniques called swing and spin. These balls are ideal for coaches to train different bowling techniques to the kids and beginners. The cricket practice balls are suitable for indoor and outdoor use. They can be used on hard surfaces such as turf, gravel and PE sports halls for training and practicing. The balls can be used to practice batting on grounds, nets or turfs.
