The Star line is created with a special blend of grippy, resilient polymers. Star plastic offers the same outstanding durability of our regular Champion plastic, plus improved grip like our Pro plastic. Star discs have the same flight characteristics as Champion discs, but are slightly less firm. High performance, longevity, and superior grip make Innova Star line discs a great choice for your game. The XCaliber is for those who have got to have the biggest and the baddest. Extremely fast with glide and stability. This is the one for confident bombs in windy conditions.
