Great helmet
Been struggling to get a helmet to fit my 13 year old son this hat fit really snug
MEDIUM in the adult helmets was too large for my petite head but it’s clear that the ‘kids’ helmets are the exact same as the adults just with fewer colour options (sadly). This SMALL helmet fits me great and is ponytail compatible.
We are very glad to hear your satisfaction with our product and look forward to seeing you again very soon!!

Great product and price
Straight to the point - do not buy this - you cannot adjust the angle of the straps, unlike almost all other helmet brands! As a result, you end up either with the strap so lose that the helmet can slip right back off your forehead, or if you try to prevent this, it has to be ridiculously tight against your adams apple! If you're going to bother wearing a cycle helmet, you need it to be fitted correctly otherwise it won't protect you. And if there's one area where Decathlon / BTwin should not be trying to save money, it is in ensuring that the straps can be adjusted so that they fit correctly. We bought this as Decathlon/BTwin can normally be relied upon for good design and great value, but I'd say this design is flawed - potentially fatally!
Brilliant helmet for children at a very reasonable price
Bought this helmet for my son and he loves it.Great product at a great price.Quick delivery couldn't ask for anymore.
Helmet looks very nice and fits perfectly!
