Looking for the thinnest.. Fit's closes to your head.. Sick of the mushroom head look...
Any ideas??  

In my humble opinion, you are going down the wrong road.

Thinnest actual DOT approved beanie is still going to require 1-2 in of Styrofoam to absorb impact. If you want the stylish look, go for a Novelty helmet. Most of them have a little DOT sticker you can slap on the back.

BTW, got a friend who destroys his old real helmets with axes and sledgehammers. Tells me it takes several whacks. Bet I could crack a novelty with a 8 oz tack hammer.  

As someone who recently had to throw a helmet away after an accident, I can tell you that buying a helmet for the way it looks is a bad idea.  

woman was killed here (Tennessee) recently while she was wearing a novelty helmet and the rear tire blew out on her husbands bike.  He lived, she didn't.  What a waste.  Things may have been different if she had a DOT approved helmet on her head.  

There is what I think may be safer helmet than DOT/SNELL, but, it's not legal in the US.
Canada, and Europe do a different test on the helmet, it's a larger strike force, but, it's only done once at any spot. I believe a 2nd hit is done on another part of the helmet, at the same higher force. Acceptable G's are lower.

I would consider slapping a DOT sticker on one of them, but, I understand the strengths and limitations of those helmets.

Novelty helmets on the other hand are just on the head to avoid a ticker. Women in Tennessee probably would have prefered the ticket.
