In the most challenging rugby matches, players must be aware of every situation and be ready to react to anything their opponents may throw at them. In order to improve their ever-changing skills, players need new initiatives to test their reactions. That's why Gilbert has worked with Richie Gray, former Springboks, Blitzbokke, Scotsman and current coach of Montpellier, to design the best catch/pass system to increase players' awareness and skill level. Available individually for the first time, the Control-A-Balls each have a slightly different behavior. The balls included are: match, light, heavy, no grip and unstable. Using these different balls at different times before using a standard ball met challenges the player and improves their responsiveness in match situations. Control-A-Balls are available in size 5. If you want to improve your performance when it counts, Control-A-Balls are exactly what you need to take your training to the next level this season. Each ball comes uninflated and should be inflated to 9-10 psi for optimal performance. The unstable ball will also need to be filled with water. Below is a guide on how to do this.
