I gave my ventral air SPIN to a friend and picked this up. It is almost identical to the SPIN tech from looks but has added minimal padding towards the back. This helmet in the same size feels slightly more locked in than the SPIN technology. Still the same comfort and airy feeling. I trust MIPS technology as I like to believe it saved me in my hockey helmets.
Overall the helmet is fine. It is light and it vents well. My only issue with the helmet is this eye garage. The vents aren't quite wide enough to keep glasses tight and the "eye garage" doesn't provide any extra slip protection if they aren't in contact with the sunglass arms. If you don't take your glasses on and off, then no worries. If you do, be prepared for your glasses to potentially feel like they're coming off before the "eye garage" catches the ends of your sunglasses (the tightest part of your glasses). This issue is not universal with all my cycling glasses. A smaller frame size works okay.
If you have a pair of glasses you love, try them with the helmet, before you hit the road/gravel/trail.
Was dying during the PDX heat wave in my old Smith with the straws. This new POC feels like I'm riding without a helmet compared to that thing. Long oval head (Arai Signet is my usual motorcycle helmet) and fits well, works with with glasses (tried with Tifosi Sledge, Rapha Full Frame and Smith Ruckus). Liked it so much bought a second one as backup.
It was time, 5 years, ti get a new helmet. I picked this one for its price and looks too. I hot much, much more. Light weight (I have to check ever once in a while to make sure I even have a helmet on); much better looking in real life than in the pictures; good and comfortable fit, it is snug with comfort; it holds my glasses well when I don't need them on.
