I’ve had the original POC Octal for some time now and I love it. It’s a great helmet. This helmet improves on the model. It’s still a super light helmet that feels more substantial than most others in protecting your head. However, loses some of the bulk and the weird way the straps stuck out. It looks neater and less bulbous and the straps sit flush to the face. Which, works great with non-POC glasses. The eyeglass garage has even better grip than the previous version.
The Spin technology is a tremendous win for me. MIPS additional layer always seemed like an over done solution. SPIN uses existing pads with no added layer, heat, or discomfort. Great Job POC!
Sizing definitely is a little different than the Octal. I was using a large Octal. However, I was able to fit in the upper range of a medium in the Ventral. Which, I was cool with. It still has that POC look but The medium looks a little smaller on my head.
For being an aero helmet it vents very, very well. Even on hot days it is more than adequate. Those large front vents pull in plenty of air. I have a few helmets and this definitely my favorite. The white color is highly visible in those early morning or late afternoon low light conditions. It definitely my go to helmet during those times.
