I tried all those racer-replica helmets over the years. I still have new (but very old) Koscinski and Rainey helmets, and through the years have pretty much tried them all, including the Vemar.
This blows them all away for silence inside the helmet, comfort and fit, crash protection, minimum weight, anti-fog, ventilation, and built-in Scala with FM and external (iPod, XM, whatever).......
