Z20 Aero MIPS Helmet

Where do you begin with helmet reviews. Well let’s start below:- FIT: The helmet according to the sizing chart and measurements I took and ordered fit to a “T”. In fact, same sizing (large) as my Bontrager helmet. When tightened, it was snug and had no flop and did not create any unusual or pesky pressure point issues.- AIRFLOW: While I will agree I was riding 68 degree weather, the flow through the minimal venting was sufficient and even on a 95 degree day will suffice. I wear a skull cap even in the hottest of days to soak up sweat. I read a recent review by a customer here stating it was hot and the sweat retention too much. I would suspect she does not know you should wear a under helmet cap to help reduce that drastically even in the hottest of days. The air across the top of the head was good and this aero helmet should not be a issue next season when full on heat.- DESIGN: The design is stylish but mainly functional. I really pay secondary consideration to style. The vents are placed as well as can be to retain aero functionality but allow sufficient air to get in. Not sure if a midline vent with a slide closure on the hottest of days would benefit but maybe a consideration for a re-design by Bell for the future.-DURABILITY: That is yet to be determined. Stay tuned. But on appearance and a detailed hand inspection, seems to be well constructed without any issues to note.-PRICE: Insane! And it is not even the most expensive. No bicycle helmet should be over $125 ever! But to get more top features, unfortunately, you have to pay.Is this a 5 star helmet? I would say a definite 4.5 right now. But since Amazon which I deplore on their 1 star increments without ability to take .5 off for issues, I gave benefit of the doubt. However, I will change it if warranted down the road.

The measurement/fit guide were spot on. I'm a medium in most helmet brands but have trouble finding a medium that works because a lot of them are made for people with oval shaped heads, I have more of a circle head- this one works well for me.It's also pretty light weight, I hardly know it's up there. Also stays pretty cool for having so few vents. Works well with sun glasses too.

Well made and comfortable. I also like the lack of air vents for raining days. All that being said, it does look super bulky. Makes your head really large. So, if you are looking for something that looks streamline, this is definitely not it. I tried the white one first, it looks like a giant egg on your head. So, I went with gray/red. A little better. I do feel like this helmet will protect me. Function over fashion.

Excelent helmet. Lightweight and confortable.

I liked how this helmet fit me, I've tried several other helmets including Kask, Giro, and some cheap stuff and this was the most comfortable of all.Then I fell during crossing the railroad, and I could feel that my head hit the road pretty hard. I had bruise on knee and elbow, but I was able to walk away from it. Helmet's foam cracked, but outside was barely scratched. So I went out and bought same helmet, different color. I am confident that if I do get into an accident again, it will protect me again.

Great fit, light and comfy. No complaints about ventilation. My precious helmet was a Specialized Propero II and I can't tell much of a difference between the venting between the helmets during those humid summer days in the South.

Really impressive helmet. I have a Kask Protone as another helmet and can say the quality of the design and manufacture of the Bell is first rate (think it beats the Kask). Ventilation seems much better then it looks and it is definitely fast. Fit is more generous then the Protone, but snugs up as needed.

The helmet worked fine for about a year, then for some reason the adjustment in the back somehow melted. I have no idea how this would’ve happened. I actually don’t live in Las Vegas anymore, so I it wouldn’t be the climate. Perhaps just inferior materials? Probably not going to purchase a Bell again when Lazer, Kask, etc. offer more compelling options.
