Are mens and womens helmets the same?

Apart from the colours, are they the same shape/fit etc? My helmet is broken and my wife has said i can borrow hers until i get a new one (if it fits – luckily it is plain white). I have searched but haven’t come across anything, does anyone know?

As far as I’ve been able to determine they are just the same interior, though the ladies version may not be available in larger sizes.

Well, just tried and it doesn’t fit so off to look for a new helmet. Now to try and find a good deal.
