Like a hot knife.
When the number one thing on your mind is aerodynamics, the number one thing on your head should be the POC Octal Aero Raceday helmet. The Octal foregoes vents in favor of aerodynamic efficiency. To make up for the vents, POC lined the Octal with Coolbest pads, which promote airflow and manage moisture to keep your dome dry and cool.
Safety considerations are handled by POC’s impact-dispersing unibody polycarbonate construction and strategically mapped EPS foam. POC also molded the straps directly into the liner for aerodynamics, comfort, and durability. Size adjustments are made with a twist of the adjustment dial.

Another Great Choice!

I already own a POC Octal Raceday helmet (L, White). It’s the best helmet I’ve ever owned. See my CC review of it. However, because it is so well ventilated I went and purchased the POC Octal Aero for cooler and winter riding. To keep the noggin somewhat warmer on those colder days. I use the regular Octal for hotter days in the saddle.
Well, it was another great purchase because it was exactly what I needed. I really could care less about the aero benefits. I just wanted something that would retain heat a little better and it delivers in that area. Don’t get me wrong it ventilates well. You can certainly feel (and hear) that one vent sucking air in over your head but not enough for me to use it over my regular Octal on a hot day.
I also don’t mind riding in rain to get my miles in. So it’s my go to helmet on those wet days in the saddle. It’s smooth profile is perfect for keeping dry in any temperature.
The large fit me perfect. Which was weird because my non-aero version seemed to fit me a little bigger. So much so that I almost went with the Meduim this time. I’m glad I did not. The Aero is true to size.
I know these helmets are not cheap but I had to have them both. One for each season. I’m glad I purchased them. It’s a quality product that you soon forget that your even wearing but feel secure that your head is substantially protected. I bought the Navy/Black version of the Aero and It looks Dope! I highly recommend these helmets.
Great intro into Aero helmets
- Familiarity: I've used it several times
I use this helmet for racing triathlons and it works great. The air vent seems to work far better than I was expecting and while not "fully breathable" I have yet to get overly hot in it. ? I use the Poc Octal MIPS for my training helmet and this as my race helmet!

I am now on my 2nd POC Octal helmet. First one I crashed on my bike, and yes, my head did hit the pavement. This helmet protected my noggin. The helmet had scrapes and the Styrofoam compressed on the front left corner of the helmet, but the plastic outer shell was never perforated by the pavement. So protection of your head, which is the most important thing with a helmet passed my usage test.
As for the helmet usability, I also give it high marks. it is areo without the need to keep your head in a tucked areo position all the time and end up with a sore neck.
Ventilation is also very good. Never had an issue in heat, and I've used it for ironman's in the middle of summer.
how is the ventilation with this helmet?
I've had the regular Octal Aero since fall. It's got a one central vent, which I think this lacks. Heat doesn't usually bug me, but days in the 80s have me wishing for a more ventilated model. So a POC w/ zero vents? Can't imagine it beyond short TTs or chilly temps.
My head circumference is in between sizes. Do the size numbers have adjustability outside the specified range? Just wondering because I occasionally wear a hat under my helmet.
I doubt there is much room outside the specified range (it's a pretty generous range on the sizing chart). I just ordered a Large for a 58 cm noggin and the feel is great and comfortable, but the fit is just a little big and I'm going to compare it with a medium. I'd say, especially for aero purposes, go with the smallest helmet that is still in your appropriate measurement range. Unless you have a really bulky hat, of course. (then just measure outside the hat while wearing it)
