Great helmet!
This helmet honestly feels like a much more expensive piece. The padding is soft, great ergonomics, it’s extremely light weight and the quick release strap is a cinch. I rode with mine today, and I know exactly where I’m going to buy another one should I ever need to

Terrible quality!
Helmet is ok for the price if you ride a scooter. After about a month continuous wear the padding quickly deteriorates. Also the rubber vent piece I had to epoxy on to stay and the cheekpads constantly unsnap. The wind noise on the sides are awful at speeds 60+, can't even hit 100 because the helmet pushes back against your face. Now after a couple months the visor flaps open and close which isn't concerning at the moment, it's just annoying. I have two of these and both have same issue. Very cheap helmets for street bikes! Not recommended

Worth purchasing
I got this helmet for my gf so this review will be her words. Likes: comfortable padding, convient flip down sun shade, light weight Dislikes: just one, description said double d ring for the chin strap and this one came with ratchet I'd like to point out that I bought her a small and I wear an icon in large and this helmet fits me pretty comfortably.

A little bit of glue goes a long way.
I'd have given it that other star if it wasn't for the fact that the little rubber piece at the front of the visor opening comes off whenever you want to carry your helmet around by the usual place of the face protection guard. It is only little studs that the rubber bit sits on and is not that tight so came off in my hand. It's only by chance that I noticed that it came off. I think I'll just put a bit of glue on to make sure it doesn't come off so freely again. Just don't know why the makers don't glue it?

Good helmet
Good comfy helmet with clear visor and pop down sun visor. A fair bit of wind noise but very comfortable

Bon rapport qualité prix
Très confortable et de bonne facture pour le prix la ventilation est un peu juste et je trouve le casque un peu lourd mais il fait le job à voir cet hiver pour la buée. La visière pare soleil se déclenche facilement. la taille est conforme par rapport au standard

Great value for money!

Sehr schöner helm
Sieht gut aus, passt und ist bequem, das einzige was ich zu bemängeln habe ist das wenn zu stark ausatmet, das Visir innen stark Beschlägt, besonders lästig im Winter, im Sommer bisher noch gar nicht
