GiroAerohead MIPS Cycling Helmet

The Giro Aerohead MIPS is a superb bicycle helmet. By two orders of magnitude the best I've ever owned.It's light and fits extremely well. I hardly notice it being on my head; the main noticeable effect with the visor down is great eye protection. There's no drying of one's eyes from the cycling wind.The Aerohead is cool. I rode with it yday and today in 90 degree sunny weather and never felt hot. The airflow system works.Presumably, the Aerohead is indeed aerodynamic. Any objective exploration of aerodynamics in real-world conditions is an exercise fraught with complexity. Still. I ride a 2016 Lightning Phantom and a very much older P38/F40. So, SWB's with relatively upright seating position. I measured 0.5-1mph faster than usual on the Phantom on a known trail, on two consecutive rides.My P38/F40 aluminum seat is at a fabricator's for welding repairs of cracks. I will definitely try the Aerohead on the fully faired F40 as soon as I get the seat back; I expect its effects to be remarkable.(Keep in mind what 1mph really means. Air drag increases with the square of one's speed, and the power to overcome air drag increases with the CUBE of one's speed. For example, 22mph takes 15% more power than 21mph, for the same machine and rider. Conversely, one can decrease drag and go faster for the same watts output.)The visor feature on the Aerohead is a great idea. I've mostly ridden with it down over my eyes, with sunglasses on underneath. Yet more surface area protected from skin cancer! Yet the visor can be attached, via its very powerful magnets, to the helmet leaving one's face exposed. Might be cooler in extreme heat, and certainly useful if dusk descends towards the end of one's ride.This little beastie also looks RAD. Especially in white. Sort of a cross between an Imperial Storm Trooper helmet and a Ford Motor Company American Helmet Model No. 8.You may have to Google that last one ...

I like how comfortable the helmet is, and it definitely seems to make me more streamlined when riding.

i got this last night and took it out for a 110miles ride today. i purchased this helmet based on the recommendations that everyone gave. here is my own personal experience. i started this ride in the dark and had the vvisor up. it stays in place. when the sun came out, i put it on. wow....it dampens all the noise! it does make me ride faster when i go into the tuck position. i rode faster while spending less wattage. i was worried that the helmet would be hot to use in houston in early september. the helmet with the visor up did blocked the holes but then it was still cool. once the helmet was in place, i never felt my head getting hot. the temperature got up to about 86/87 degrees. i will be using this for my ironman in chattanooga in late september. great helmet.

My head circumference is 57 cm. I previously bought another Giro model in size M, and it turned out to be a tight fit, so there’s no way I could wear anything underneath, like a cap. For this model, I chose size L, and it fits perfectly. I probably have a wide head))

I have a somewhat wide face with fat cheeks, so the lower part of the shield hits my face. After a long bike ride, a crease for sure shows across my cheeks. I still very much like this helmet though. On a hot day, the air circulation going through the helmet is really nice! What I like to add too is the air while riding does not circulate over the eyes (but over the top and sides of my head inside), and not causing eye dryness like my other helmet (that is my problem with the Giro Air Attack). I'd say this helmet is also not for the self conscious, it does look like a Star Wars helmet and you get alot of differing looks from "whoa cool!" to "you look ridiculous" (what my wife said). I am not overly self conscious and I like the benefit of being aero with a cool breeze inside the helmet. Recommended for those that do spend that extra to go for the small percentage gain over other helmets.

First things first......this helmet is expensive! I just started riding for triathlons and needed to get a newer bicycle helmet than what I had. I had looked around in a bike shop and they were around $100 or so. Plus, needing the right sunglasses too would have taken me probably to $200 or more. I thought I would take a chance on a really nice helmet with the visor and based on previous reviews. The helmet showed up and was I really wowed when I took it out of the box! It is light and comfortable. The adjustable strap made it that much easier to get a proper fit. I also wore a headband with it and it was still comfortable. I rode for and hour and a half and would have gone longer if I could. This helmet is fantastic. The visor is magnetically connected and comes off for cleaning or if you don't want to wear it. It was a worthwhile investment for my melon!

I love this helmet and is the one I should have bought to begin with. I was using another helmet without an integrated visor, causing me to wear glasses. The top rim of the glasses would obstruct my forward view while in the aero position and the glasses would fog up if there wasn't enough airflow around the lenses and sweat would occasionally drip onto the lenses. Giro's integrated visor allows a full range of unobstructed view, without fogging up or sweat dripping on it. The visor is held onto the helmet by a series of magnets, allowing for easy removal for cleaning and then reattaching. The aerodynamic shape and cool artwork/colors make me feel faster. I feel like I'm riding faster too.
