About this item

  • MIPS EVOLVE CORE — All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giro's Mips Evolve Core-equipped helmets is to reduce rotational forces while enhancing fit and comfort by combining the Mips slip plane with the helmet's adjustable fit system. Giro believes that helmets equipped with this technology can reduce the amount of rotational force that may be transferred to rider in certain impacts.
  • RUGGED: In-MoId Construction fuses a tough polycarbonate outer shell with the helmet's impact-absorbing foam liner. The fusion process allows for better ventilation systems, making in-mold helmets lighter and cooler than traditional helmets.
  • ROC LOC SPORT FIT SYSTEM — The Roc Loc Sport fit system offers easy one-handed operation with a 7cm adjustment range. Its confident clicking feel and sound lets riders know that the helmet is adjusting to a comfortable fit. With comfort similar to Roc Loc 5 and ponytail compatibility, the new Roc Loc Sport fit system brings premium function to sport level helmets.
  • DEEP INTERNAL CHANNELING — Combined with the massive 19 vents, internal channeling forces air to flow over the scalp, providing remarkable cooling power.
  • Quick Link removable visor - Reflective rear decals

Customers say

Customers like the quality, weight, ventilation, adjustability, and appearance of the bike helmet. For example, they mention it's well made, lightweight, and has plenty of airflow to keep their head cool. Some appreciate the rotator clip and the chin strap has only one adjustment, making it easy to fit almost any size. That said, some say it'd be a good choice for those looking for a nice looking, sturdy helmet at a reasonable price.

This helmet is lightweight, comfortable, and good protection from falls. I chose white to reflect the sun. On a hot humid morning, I biked 20 miles wearing this helmet. Despite stopping 3 times to drink water and eat a clementine, I wound up dehydrated. About a 1/2 mile from the car, I stopped the bike, intent on getting off it. I put my feet down and leaned over the handle bars feeling very sick. The next thing I knew I was face down in the dirt after passing out from low blood pressure. These photographs were taken after the spill. The thin visor had popped off, but it didn't break. Amazingly, I didn't get a scratch on my nose, face, or head, and my neck was fine. I wound up with a scraped knee, huge black and blue on my chest, and 2 bags of IV fluid. The helmet was unscathed. STAY HYDRATED, FOLKS!

I love that this helmet fits so perfectly! It is lightweight, and is so comfortable. I'm also partial to the color yellow, so this one is right in my wheelhouse! It's easy to see me coming...

I purchased this primarily to move up to the improved MIPS technology. While that tech change is not visible to my novice eye, it gives me confidence to be riding with the latest safety feature.

There's an extra plastic clip-on on the front of the helmet. This must be for cosmetic purposes only. Honestly, I have accidentally dislodged it several times while putting on the helmet. It's easy to re-install.

I'm very pleased with this helmet!

This helmet is very light and comfortable. It is easy to adjust for different head sizes. The only down side is that you may forget you are wearing it.

While it seems as sturdy and safe as other helmets, it breathes well on hot days/long rides.... most of the time I forget that I'm wearing it. I can't say too much about how it performs in a crash ... yet. When that unfortunate day comes, I will hopefully be able to pro9an update.

The dial to adjust size works nicely; the helmet feels secure on my head, and the chin strap does not rub or chafe regardless of the length of ride I do.

I highly recommend it for comfort, especially if you don't mind looking like a dork when you forget to take it off as you walk into work, a bar, or a restaurant (yeah, that's from personal experience).
