It is a very beautiful and practical helmet. Bought it for my 3 year old daughter, she was immediately very enthusiastic and want no longer depose him. You could equal him alone close (light Habdhabung), while opening still needs some help, but this is a good thing. The design is very cute. The sizing of 50-55 cm I find optimal. Although my daughter has a Kopfumpang of 49 cm, but everything fits perfectly. I can only to anyone who wants a helmet where the margin is 5 cm, know about this. Price is also perfectly fine.
