The leader.

Aerodynamic road helmets became something of a trend over the last couple of years, with Giro's Air Attack Shield Helmet leading the way. It doesn't lead from the wind tunnel, though, which is where so many of these helmets get developed and tested. It leads from the velodrome, where the pros from BMC Racing recorded times that were 56 seconds faster over 40 kilometers. It leads from Kona atop Cave, the world champion from Great Britain. Now, it's leading into 2015 with the same design that makes it a favorite for pros across so many disciplines.

The helmet features the same front area as Giro's Selector time trial helmet, with the back — or rather, the lack thereof — really setting the Air Attack apart. Wind tunnel testing proved that passing air still "thinks" it's moving around a long tail, when, in fact, the excess material no longer exists. In addition to now having roughly the same minimal drag (only 11% more) than the Selector, the Air Attack provides a drastic increase in weight savings, 264g versus the Selector's 430g.

The low-vent design initially inspired fears of 100 degree Fahrenheit days with a stifling bowl on our heads. Giro researched solutions to this concern with something it calls the Therminator, a head-shaped object equipped with sensors. The Therminator went into the wind tunnel and data came out, showing Giro where vents work, where they don't, and providing a map for ideal ventilation with as few vents as possible.

Giro also found that as air hits the rider, there is a very high pressure zone right at the forehead. In response, the Air Attack's new fit system, known as Roc Loc Air, suspends the rider's head off of the EPS, allowing air entered in that front three millimeter portion of the helmet to flow over the top of the head and out the large, strategically placed back channels. Amazingly, the Air Attack boasts 97% of the cooling efficiency found in the barely-there minimalist Aeon helmet with an 11% boost in aerodynamics.

The polycarbonate shield is the result of a collaboration with the team at Zeiss Optics, who use their considerable wealth of lens knowledge to imbue the shield with high-levels of both durability and clarity. The lack of any framing means that the shield provides a wider field of coverage and view, and the magnetic attachments allow you to spin the shield around when you want nothing between your brow and the wind.

  • In-Mold polycarbonate shell with EPS liner
  • Air Attack shield with magnetic fasteners (Gray/Silver Flash included)
  • Six vents with internal channeling
  • Roc Loc Air fit system with removable X-Static padding
  • Slimline buckle

I just love this thing

  • Familiarity: I've put it through the wringer

I don't find the tighten/loosen adjuster too small as another reviewer did. This helmet is surprisingly cool and definitely efficient too. The built in lens is easy to remove while riding.

However, the built in lens also takes a little getting used to. On my first ride I had an itch on my nose and when I scratched it I pushed the lens off and it landed on the road behind me; had to pull a "u-ee" to pick it up;fFortunately I was riding solo and no damage was done. I've sinced learned my lesson.

Fits me nicely too (as Giros have in the past).

Great helmet

  • Familiarity: I've put it through the wringer

I purchased this helmet for triathlon use as my Giro Ionos paired eith my normal glasses didn't work well in aero position (had to keep pushing glasses up to maintain good site). The helmet is much cooler than I expected it to be, although I haven't used it on a scorcher yet. At first I was surprised and worried at the shields height, thinking it didn't come far enough down on my face to be effective, but in aero position it is great, even in rain it kept water out of my eyes and vision clear (until it got covered with droplets due to a downpour). The vision through the lens is great in a variety of lighting from blue bird to overcast and cloudy. Magnet strength is great and keeps the shield firmly secured when riding with it up. Helmet fit is true to size measurments. All around great product, highly recommend.

I am very interested in the helmet blue, (in the front) red (on the side) and black with the giro letters in red, in a Small size. I need it rush. Could you please verify it id you have one available?
Thanks in advance

It looks like we are out of stock in that color (LE Matte Black/Glowing Red/Blue) and our buyers do not have any more on order currently.

Let me know if I can help with anything else!

Got it for TT training

But I like it so much I may use it in competition instead of my teardrop.

It's much cooler than I thought it would be, both aesthetically and in temperature.

What you see is not what you get.

  • Familiarity: I returned this product before using it

Be aware that the blue/black helmet pictured on the website is NOT accurate. I ordered one and this is what it actually looks like. Nothing wrong with the design of the helmet, but I will be exchanging it for a different color.

A Good Addition to A Quiver of Helmets

  • Familiarity: I've put it through the wringer

I'll admit, the Giro Air Attack Shield is not my only helmet. I also have a Kask Vertigo and a Rudy Project Wing 57. I use my helmets for both triathlon training as well as triathlon competitions. The Giro Air Attack Shield claims to have great aerodynamics, but so does the Wing 57. The Giro Air Attack Shield, however, is great for very hot weather. Too have great aerodynamics, but also have great ventilation is quite an accomplishment. I've used the Air Attack in triathlons when the weather was incredibly hot, and I never felt like I was over-heating (all while using a helmet with great aerodynamics). I also really like how you can flip the shield upside down and get it out of the way while riding if you decide you no longer want to use the shield. The shield attaches to the front of the helmet using magnets. Most helmets with shields have no mechanism for moving the shield while riding, without removing it completely and stashing it somewhere on your person. So the design of the shield is great.

One downside of the helmet is the the mechanism in the back used to cinch the helmet onto your head. It's a very small, serrated dial and, to be honest, it's hard to operate particularly during a competition.

In the end, you can't go wrong with this helmet.
