Oakley Aro helmets - sizing Q

Anyone have any experience with the fit on these helmets or reviews? Specifically the Aro3 and Aro5 helmet.

I’ve got a small head and typically wear either a small or a medium. Sizing window on these helmets are small and no retailer around has any for me to try on.

They run smaller than advertised. You’ll at least need a medium.

ARO7 also runs on the small size.

Thanks for the tips.

I have the ARO5 and it fits small and for me a touch tight around the temples. Otherwise it is the “slimmest” helmet I’ve owned in terms of profile.
