The cap fits snugly over a 47 cm head circumference (bb 10 months). My son does not like his establishment but once on the head, he does not even try to remove it. This protects head gives a nice look to small boys, soft colors. It is true that the scratch will not last long so strong handling, but once set you do not need to change the position of the "Velcro" or at least only when the head of the baby grows. And the closing scratch everyday is very good. The only small snag is sweating under the bonnet, the hair is wet and it quickly in rooms at 21 ° (even when I give a 5/5 after having in our possession more caps and suck at the same price)
