The 70's Gold Standard of Helmets.
You can now get a 2014 version of this same helmet.
There are a bunch of imitator clones these days which include the Biltwell and the Foo-Foo Fashion statement Ruby, all of which do not have a flip-up shield. What hipster decided that Flip -up shields didn't cut it, in their narrow focus formula. Certainly not a very serious rider who plans on doing some back road scratchin'. When wearing a full face helmet, your flip shield is absolutely your best friend.
It gives you an airtight, clear view of the action. You can crack it open to any degree and when its time to go you snap it shut, like Steve McQueen snapping his seat belt in, in Bullit.
