Shark Helmets | Sizing question

[Karate.Snoopy]

Owners of Shark Spartan helmets, I am a size XS in Arai, M in AGV & Scorpion.
Size chart suggests I get a Size Small (55 cm circumference) in Shark, but given the variation by brand I wanted to see if anyone had experience with these helmets and what they thought about the sizing?

I’m a L in Shoei, Bell, and Scorpion. Bought a Shark XploreR last year to try on and a L fit me well.

The more important thing is that shark helmets are generally very narrow. They really are a helmet that is best to try in person.

It depends. They used to be long oval in shape (like the RSX I had), but lately they are more round. I agree it is best to try in person. I am very surprised at the OP sizing of his Arai vs others. I suspect one of them is not a great. Fit. Arai has the most head shapes in their lineups, but are super expensive
