Giro Aerohead MIPS Triathlon Aero Helmet Review

Giro Aerohead MIPS Actual Weight - Medium
updated on 12/10/2016 to reflect 6 months of use and many races.

The Giro Aerohead is appearing in the wild. I actually just got mine today. I picked up a medium (55cm-59cm) and it fits true to size in comparison to my past aero helmets. For the weight weenies out there, mine measures in at a hefty 448 grams but given the aerodynamic promises of this helmet that will be very easily offset. You can get it next day via Amazon Prime: Giro Aerohead Mips

I wanted to briefly discuss my helmet choice for the remainder of the year. I do not have a helmet sponsor, nor would I want one. Having a helmet sponsor costs more than it is worth for almost every sponsored athlete unless it just happens to be the exact right helmet for the person.

My previous helmet was a helmet that tested well on many people at ERO. ERO is a company that tests aerodynamics outside the wind tunnel and is usually done on an indoor track. That helmet was the LG P-09. Although I hadn't actually tested the LG P-09 myself, given that it tested so well for so many people I decided that probability would dictate it being a good buying decision. I did happen to go to the wind tunnel this year and the wind tunnel confirmed the LG P-09 was the fastest helmet for me.

With that being said, there is a new sheriff in town. Giro developed this helmet in conjunction with ERO and they have put a ton of engineering behind it. Specifically the shape of the lens is where a lot of the aerodynamics of this helmet comes from. Despite not testing this in the wind tunnel myself, I am going with this helmet from here on forward. Although the Giro Aerohead Ultimate MIPS is technically faster, it is also significantly warmer than the regular MIPS and for triathlons over-heating can be a real concern.

The helmet is nice, it feels nice, it feels sturdy, and it feels fast. It is hot however and I did have some fogging issues with this at the super humid Ironman Cozumel 70.3 race. Luckily you can easily pull the visor, and flip it upside-down on the helmet. There are internal magnets to hold it in place in this second position and they are fairly strong. Over hundreds of miles, the visor never fell off once in either position.

Overall, this helmet is a winner and my aero helmet choice until something better comes along. The following is public marketing data from Giro. Please note, I purchased this helmet with my own money and have no support from Giro. If you want to help support my writing I encourage you purchase via this link as that helps a little!!

  1. Interesting. I just ordered an Aerohead, primarily because I'm concerned that my Selector is too hot as I am moving up from 70.3 to Ironman with Boulder being my first. Somehow I missed the "warmness" comparison that included the Selector. Looks like I won't be getting much cooler.

    1. Yep I can attest that it is hotter than my LG P09 which despite testing fastest in the wind tunnel for me, was also the coolest feeling helmet as well.

  2. My concern here would be over the probable big decrease in aero benefits without the visor. It rained at maybe 4 out of 6 events for me this year. My Kask has a great visor but it's impossible to use (too foggy) in damp conditions. I think the kask isn't bad however without it's visor. This giro looks like the aero shape is quite poor if you had to go without it. Dry conditions, this looks awesome

    1. 100% percent agree. The visor is an integral part of this helmet and Giro even says the shape was designed in conjunction with the visor. That makes not using the visor a huge disadvantage. For this very reason I have kept my LG P9 as well and I would use that for potentially very humid races or raining races.

  3. LG p9 is on my list of helmet with the areohead

    1. Should be mentioned that my P9 is the old one, pre-recall. I believe post recall it was fattened up and thus probably not as aero.
