Works for me
Love this helmet - easy to adjust, well vented and looks cool. Replaced a large Specialized helmet with a large in the Catlike Whisper Plus. I've also got a large Giro mountain bike helmet . All three work ok for my head. I've had less luck in the past with Giro Atmos - for me the top of the helmet pushed down on the top of my head. Shape seems to vary by manufacturer, so hopefully this is helpful.
