Fits perfectly, and I have an enormous head!
I have been searching for months for the perfect looking helmet that provides top notch safety for my melon. I tried everything; Bern, Giro, Triple 8, Nutcase, Protec, etc. My head is shaped in a wierd way, to be honest. Its more "longer" than "wider," like an oval (I wear 7 5/8 - 7 3/4 fitted caps). Every Large, XL, and XXL helmet would make my head look like a mushroom, and they all fely very uncomfortable. Then I came upon the S1 Lifer Helmet in XXXL (23.5"). I read the reviews and loved the idea of the deep fit design. So I took the risk and ordered one online. When I finally received it, I was relieved that I found a helmet that fit me perfectly, and didn't make my head look like a mushroom. Relieved that I can finally stop looking for a helmet. The black gloss looks amazing! I am now a fan of S1 helmets and I highly recommend the S1 Lifer for everyone, especially for those who have an extremely large head like mine.
