Super comfortable helmet. Plenty of vents to keep your head cool. Boa retention system is very stable and fine tunable. MIPS technology will keep your melon safer, though I haven't tested it yet. I am very happy with this helmet, the white color is really sleek looking and I've had several compliments on it in group rides. I have a pretty big noggin (7 12) and the large fits me perfect. Comes with a breathable storage bag so your shiny new expensive helmet doesn't get scratched in your gear bag. Oakley had already proven themselves with snowboarding and skiing helmets, and it shows. Great quality, and actually cheaper than equivalent helmets such as from POC, Kask, etc.
