What helmets are the best ventilated on the market? I’d imagine some of the POC helmets are pretty good.

Catlike Kilauea. Came out last summer but rather hard to find. 37% of front of helmet open
....per their advertising.

I've used an Octal for several years, and despite moving to the South of France and enduring a fairly hot summer, feel no need to change. During the colder months, a merino beanie worked fine. Their newer offerings look like they attempt to combine adequate ventilation with some modest aero gains, but just how aero they really are is, well... debatable. Given helmets are fairly personal purchases relative to one's head shape and riding environment, I'd happily buy another POC in the future.

Best,

No complaints with my Limar UltraLight+ on ventilation... or much else for that matter.

I've also got 2 octals and they're great for ventilation. Coming from having used a specialized Prevail and Catlike whisper. The Octal seems a lot better but that could also be partly fit

The type, size, and shape of the head band may be as important as the overall airflow. A big difference for me is the headband. Some of them act like dams, others sponges, and others pass crap out of the way. My Oakley (same as POC???) tends to pool and dump. My Spec Prevail has the low scalp vents, which were nice.

Another thing to consider, as long as you aren’t going slow (climbing, mtb, urban), just having convection is as good as ultimate airflow. As long as you have air traveling over all parts of your head and exiting, you’re as good as having ultimate air flow. An aero helmet without many openings can cool efficiently, as long as your head is at the right angle. If you’ve got openness but no exit for the air, with the air stalled, you’ll get hot. You’ll also want some turbulence and a gaps above your head to get the air to work out the sweat, rather than having the same three channel efficiently cooled.

IMHO an aero helmet can offer adequate ventilation only at high speeds and only at temperatures up to 20 celcius. If speed is low and temperature is high no aero helmet can offer good ventilation. I often ride at 30-35 celcius and this is my experience.

Kask valegro. Protone has gotten it done for me as well.

I've been happy with my S-Works Prevail 2. I used to wear a sweatband but I haven't had to use it since I got this helmet.

I live in Florida and no matter how fast you get air going through a Vanquish, the heat still starts to become an issue after a while.

Octal, Z1, Valegro, and Prevail 2 all look like pretty good options. I’d go with Valegro but it doesn’t look to sturdy or padded.

Anyone currently using MET Trenta helmet? I'm curious how that helmet compared to Protone and Valegro.

Poc Octal that needs replacing. Tried a Ventral Air but they've messed with the sizing so the M was tight at the sides and the L was massive. Very annoying.
