I agree with the previous review to the extent that one may specify this ball is not as F-capable youth in the product description! He's just too heavy and the provider has probably no idea of the rules of football associations for the Hall rounds (myself am a trainer F-youth team). For G- and F-youth, the balls may weigh 260-280 grams and have a circumference of 51-53 cm. This one has 56 cm, the weight is but since. It's actually not that no further information is available at the Futsal balls and usually they are not even accurate and standardized. I had mistakenly ordered him because I thought size 3 is the smallest indication. Those looking for balls Bambini need size "0", there is also "Cawila". Otherwise, I can not say much for the quality because I can not play him with the Lütten (8 years), otherwise it seems to be OK.
