I bought this helmet 2 months ago and I'm pretty happy! The helmet fits perfect to my head looks cool and is very quiet during freefall. Honestly I don't trust this d3O stuff. It is very thin and I doubt it to be effective on an impact. Don't believe in the sizing charts. I choosed XL and it didn't fit. Had to go for XXL (and my head is not that big). However, I definitely do recommend this helmet!
