Helmets larger than XXL?I've got a seriously oversized head (64 cm circumference). I hardly ever can find hats that fit, and now I can't find a helmet that fits either.
Giro's ski helmet sizing chart says XXL runs from 60.5 to 62.5, so their biggest ones are about 1.5 cm away from what I need.
Any suggestions as to brands that run large, brands that come in 3XL, ways to modify a 2XL without reducing its safety, etc. etc.?
