I've tested this helmet on several occasions where I ended up in the hospital. Yes, I bought a new helmet after each "test" and my head never was the worst of my injuries.
That's why I continue to buy the same helmet over and over.
My head won't fit into a Smith, Oakley, etc size large, but the large in POC is perfect. The fit and finish don't feel as nice as my first POC octal that I got in 2018, but it is still very light, very breathable, and this one has MIPS. Would buy again
This helmet is comfy and well vented. The glasses garage is such a nice thing to have as well! Plus, after a crash at around 40mph my noggin was safe.
Fits really well. Very lightweight and comfortable. I can hardly feel it on my head comparing to my previous helmet. The L size fits the 58cm head really well.
The Octal MIPS is extremely lightweight with good ventilation. I like how far down the helmet comes in the back for better coverage.
