This is a good helmet for a few reasons. It looks good (no bobble-head look), it has adjustable vents, It fits (my head at least) very well, and it protects your dome.
My only gripe is that after a couple falls the the brim and outershell are very slowly starting to separate from the helmet. Also, being one of very few cool looking helmets, everybody and their mom will have one. I personally am not too concerned about this, but just thought i'd mention it.
