The Gilbert Omega has been hand-stitched and is an official size 5 rugby ball ideal for club, school, and junior rugby. The Omega Match Ball for games features a Truflight Valve, a unique valve shape and placement that redistributes weight along the seams of the ball to improve rotational stability, resulting in greater accuracy on passes and more control in the kicking game. The standard Gilbert grip with round pimples evenly distributed at a uniform height make the Omega a comfortable and predictable ball. 3 ply poly-cotton and cotton laminate panel means that the ball will weigh slightly more. The ball will perform better on longer kicks and passes, and generally hold its shape better than a ball of 2 ply construction. Conforms to World Rugby Specifications.
