No vote, only size specification

Because it annoyed me something that Amazon does not specify a size chart / Declaration for S, M and L in this case, as with other Vaude hats, I wanted to share my knowledge found on the Internet.
Where else can you know which size is meant for which age and which head circumference !?

Children / Kids SML
Head circumference / head circumference
S = 46-48
M = 49-52
L = 53-56

So this is not an evaluation, the hat I can not judge. Therefore, it would be unfair to give only a few stars (Vaude can not help it).
Otherwise, we are very pleased with Vaude, our daughter carries the one or other of the forest kindergarten.
