Official Indonesia Rugby balls by Gilbert. This range of rugby balls has been fully endorsed by Persatuan Rugby Union Indonesia and will be used by players, coaches and clubs across the entire country. The Gilbert GTR 3000 Rugby Ball will serve as the Official Development Ball of Indonesia Rugby. The Gilbert GTR 3000 Rugby Ball features the company’s newly patented Tri-Grip triangular surface grip pattern. The innovative new grip represents a major step forward in ball grip technology. Tests have shown that this new more defined pattern is hard wearing, and allows players more surface area contact with the ball when handling. Drawn in-house at Kuckreja, the new Persatuan Rugby Union Indonesia series was developed locally in-house at Kuckreja. The design took over a year to complete, and offers charming yet striking elements of Batik design.
