we have for our son (head circumference 53cm) cap ordered in size L and thereby related forward to the size specification of Vorrezensenten. These sizes are not correct.
Size L will fit well for head circumference 56 or more. For size 53, it will cap / head range at stake probably still the south.
What is also missing in the item description, the UV protection. This is the present model factor of 40, which is for us a toddler too little. The processing of the cap is ok - but nothing more.
Annoying Sometimes Hergeschicke. The money could also accommodate otherwise the provider.
