I'm pretty picky about helmets. I live in the southern hemisphere where we do a lot of HC climbs in very hot weather. I ordered this helmet through BTD and had my son bring it down. Wore it out into the Andes yesterday and here is what I LOVE...
-Ventilation is incredible.
-Fit is so perfect you don't notice it. It's very light too.
-Sunglasses actually fit against my head not helmet parts.
-The non-padding throughout the helmet is a non-issue. Especially in how that really helps to keep the head cool. Trust me, you will not notice it.
-The glasses docking when not wearing them is OUTSTANDING.
-I wear a 718 to 714 when buying fitted ball caps and the Medium is dead on perfect.
-One last thing...it looks GREAT on the head too.
Bought this helment cause of its weight and Boa system. Both areas were perfect but my big head wouldn't fit. it was good side to side but had too much pressure on front and back. I ordered the large, I normally wear large in specialized helmets,.
This helmet is weird that it sits exactly the way it should on my head except it is snug from front to back. Thought about exchanging for a bigger one but then I think a bigger one would sit too low. The one I have is just above the eye brows.
The most important thing about a helmet is how it fits your head. This one happens to fit my head perfectly while other brands like Giro, Bell, and Poc do not. It's comfortable and well vented. I think my favorite part is the pad that runs across the front of the helmet on the inside which does a great job of preventing sweat from running directly into my eyes.
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.
