The Handi Life Sport Blind Football: Features and Differences from Regular Football. The Handi Life Sport Blind Football is a rattling ball made of high-gloss PU and features graphics in certified colors. The bounce behavior is reduced, similar to a futsal ball. The six rattling sound chambers inside the ball further slow it down. The objective is to place the ball in the opponent's goal, which measures 3x2 meters. Two referees positioned along the sidelines officiate the match. Since there are no boards, the futsal ball can leave the field. The difference from regular football is that the ball is kicked into play rather than thrown in. Size: 3. Construction: Sewn. For whom: Youth, Adults. Weight: 510-540 g. Circumference: 60-62 cm.
