Valtteri's first racing helmet was straight from the shop shelf but when he finally got to design his own, he took inspiration from a former F1 driver.
It probably wasn't one you were expecting, though... did anyone guess Olivier Panis? Probably not - but he liked the French driver's blue, white and red design so much, he decided to imitate it.
"I was watching all of the races on TV, and he had this great race in Monaco and also very close to that time he had a big accident and broke his legs," Valtteri explained.
"He recovered really quickly and I just thought he was a tough guy. I am a big fan of blue, too, so I also really liked his design and copied it."
