Andrew, The only one I've liked is the Giro Atmos - I spent more to find one I liked look of and the fit so that I may actually wear it (am not a big helmet fan). Though that said...I've a big head. Go into a shop and try a few on.....?
+1 i have this helmet and i have a long face. i was inbetween sizes and went for larger one as it sat further down my head and looked better. Also, i noticed when trying on helmets that colour can make a difference. When i had the one before (which was also a giro but not an atmos) the red was the best, black looked bigger and white just looked like a dome, but all the same style.
this one looks like nice but may not make your tits look nice and close, you'll need a good bra for that.
Met Forte, tits nice and close, doesn't look like a mushroom. Comes in different colours, not just white.
It's the one I use, and I love it. Most comfortable one I found at the time I was looking.
most staff in an LBS will be happy for you to try out different ones, they will fully understand the need to look good on a bike!
