Size 5 - (Age 11 and older). The Felt Soccer Ball by Uber Soccer features European soccer technology and is made strictly for indoor use. These soccer balls are made to have slightly less rebound for less inside bounce which allows more play off of walls and has a soft kick feel for virtually painless play. The 32 hand-stitched panels are made of high-quality felt that will not mark your walls. Additionally, this ball is black light reactive so it's great for black light soccer games and will glow in the black light. Note: All soccer balls are shipped deflated to reduce shipping costs.
