We can recommend you any kind of helmets but there's a chance you may not like it.
Go to a reputable bicycle shop that have a large range of helmets on display and try them out till you find one that's comfortable.
If the Giro fit you, it's worth trying out the one you mentioned; the Ionos and Atmos.
AFAIK Tokyo Fixed have the Kask helmet too, not sure if Condor do them as well.
