Vettel's 'current' design is essentially a design stolen by the original of Michael Schumacher.
nevertheless, i do enjoy this simple helmet design as it's much more recognisable and reminds me of classic helmet designs that stayed in memory better.
Schumacher's design was classic, Hill, Senna, Alesi, Mansell, etc.
all those overly busy helmets nowadays aren't really enjoyable imho.
and indeed, especially with all the sponsors on it.
I'd appreciate it a lot more if they banned sponsors on helmets, but that's never going to happen.
