I just bought a Giro Revolver and couldn't be happier. With the medium thickness padding and earflaps it's great for wearing without a beanie, goggles on top of helmet.
When I take out the earflaps and replace the medium thickness padding with the thin padding, my goggles and beanie fit under the helmet.
So my advice is: don't buy a helmet that is too big. By using thinner padding or removing padding completely you can usually fit a beanie and goggles under the helmet.
