I went to the Monaco Gran Prix this year.

I found a little shop called Formule 1 that had same size helmets, but much better made (not plastic). They were cast form fiberglass and were custom lines with a rubber type compound with a steel fitting and a flip down clear visor.

They had 3: one in Yellow, one in black and one 2 in white with Monaco GP on it and checker board design and racecourse on back side (I bout one)

COST: $50.

These are great and alot cheaper than the the mini- F1 helemts sold around or the Heuer clock/displays.

Nice alternative
