Feels like you're wearing nothing at all!
I've never been a big fan of helmets and consequently don't have much to compare this to, but this is a downright awesome helmet.
-looks good (as far as helmets go)
-expensive (but well worth the cost)
I haven't crashed it yet and hopefully I never do but it does give me good piece-of-mind knowing I'll have some stylish protection on my noggin in the event of a crash. You should buy this.
