In conjunction with the Ultimate Players Association, Discraft has introduced the J*Star ('JAY-star'), which is the official youth ultimate disc of the UPA for ages 12 and under. At 145 grams and 9.5 inches in diameter, the J*Star is 30 grams lighter and 1.25 inches smaller than the world standard ultimate disc, the Ultra-Star. As a result, it is easier for developing players to catch, throw, and get better distance.
