Only down side to the Bell Metro is that if you use glasses that hook over your ears, the glasses will open up a gap in the ear covers that will let in enough cold air to bother you a lot below freezing. I have used eye protection that didn't need to go over my ear with great sucess, but the easiest solution is to wedge the ear pieces between the outside of the balaclava and the inside of the ear covers in the same spot they would be normally.

Of course, skull caps and tape when you need to is a lot cheaper than a Bell Metro, and may even be more stylish. But I am a sucker for gimmick products if I think they will work.
