Description

Legally aero.

Aerodynamic helmets are proven effective in taking time off of your race against the clock, and this end, it seems logical that you'd want to wear one for every event. But, a teardrop-shaped aero helmet is not legal in mass-start races. Giro looked at how air moves around different helmet shapes and mated the aerodynamic qualities of a teardrop design with the ventilation and compact fit afforded in a traditional helmet. The result is the new Air Attack Shield.

The general design of the Air Attack was based off of the frontal shape of Giro's Selector time trial helmet, while the tail portion has been removed. And while this seems to defeat the point of a wind-cheating helmet, though wind tunnel testing, Giro found that the air still moves around the helmet, from front to back, as if the tail still existed. It also found that the drag is only 11% more than a full teardrop shape. This instantly means that there is a weight savings. In this case, the weight of the Air Attack, without the shield, is 264grams versus the Selector's 430grams.

Without proper ventilation, the Air Attack wouldn't be the ideal choice for mass start events. To this end, Giro developed a testing device they nicknamed the "Therminator." It is essentially a mannequin head form heated to the temperature of the human body with 'thermo-couples' placed on the exterior. The information relayed from these couples allowed the engineers to map out where exactly the head stays warm and gets cool in the wind tunnel. In turn, vents were placed in the areas where the head benefits from maximum ventilation.

As for fit, while in the tunnel, Giro's engineers discovered that the forehead is subjected to increased pressure. In response to this, the Air Attack's new fit system, known as Roc Loc Air, suspends the helmet above the rider's head, ever so slightly. This permits air that enters 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. The 11% increase in drag over the Selector is balanced by a 28% increase in ventilation.

For the included shield, Giro worked with Zeiss Optics (of camera lens fame) in order to create the polycarbonate design. This resulted in a wide lens that features durability as well as clarity. The frameless as well as curved design means a wider frame of vision than sunglasses. It is held in place my three magnets, making removal easy. It also may be turned upside-down to move it out of the way if desired.

The Giro Air Attack Shield Helmet is available in the sizes Small, Medium, and Large and in the colors Black/silver, Black/red, Blue/black, and White/silver.

Excellent product!!!!!

  • Familiarity: I've used it several times

I am very pleased with this helmet and the price was outstanding! My wife purchased these items for me for a gift to celebrate our new marriage. I couldn't be more happy with this and all my items/ The only con is that when my face sweats I have to take the entre helmet to wipe my face. Other than that this helmet is outstanding!

This is THE helmet!!!

  • Familiarity: I've used it several times

This is one awesome road helmet. Good for tours, triathlons and Sunday rides... One helmet does it all. The visor is great and easily flips and attaches / detaches. The magnets are perfect design.
Get this helmet!

Love This Helmet.

  • Gender: Male
  • Familiarity: I've put it through the wringer

WOW - I'm VERY impressed.

- I thought the "gap" between my cheeks and the bottom of the lens would bother me but no. I removed that little rubber liner around the nose area as well - this way its all clear all the way around the lens. The clarity is pretty amazing and my field of vision is about 20% less restricted by the top of the frame - cause there is no frame.

- Ventilation is pretty darn good. Since the helmet "floats" above your head, the air flows in from the front vents and I can feel it cruising over the top of my head and then out the sides and back. In some ways it felt more efficient than my other helmets at cooling my noggin'.

- Form factor is great. It's lower profile (compared to my Kask & LAS helmets) looks good and doesn't sit on top like a mushroom on top of my head, despite it being designed to be worn like that. And hell.....I look like a "Tech-rider from the future" wearing it, it's so Tron/Stormtrooper -ish.

- Comfort is pretty good. But not as comfortable as my aforementioned helmets. I think KasK and LAS still beat everyone else in this regard. The Italians really know how to pad their helmets with the right kind of adjustable straps. It would have been nice if Giro took a lesson from them in strap design for the occipital lobe.

- Not a SINGLE drop of sweat on my lens after my ride. Amazing. And I sweat like a racehorse - my Oakley Radars had to be wiped down at least twice each ride because of the pooling and drying of the sweat on the lens. Also, since the Oakleys -were so close to my face, my facial heat would fog the lenses up whenever I stopped. On the Giro, the entire lens is on the helmet, so there is a big enough gap to allow for proper ventilation that dries up sweat on my face before it can dribble down and prevent any "fogging".

- Integrated Helmet Lens = No frame-bridge on my nose. No Pressure. No adjusting. YES.

I had some apprehensions before purchasing, after reading numerous reviews, but very happy I did :) No Regrets!

Love This Helmet.

Okay...but not blown away

  • Familiarity: I've used it several times

Is a little bulky/big if you ask me. And the eye shield doesn't come down low enough on the face to make it practical for wearing for long-rides without sunglasses. I was concerned about overheating, but generally I'm quite please with the cooling....note, if you get an itch in your head though, you're not jamming your fingers into those tiny vents to scratch it...endure or take the helmet off.

Is the magnetic visor sold in a transition lens? I would love if it shaded in sun and cleared up in shade. Thanks, Kiki (Photo Credit: mattkurvin.com)

Hey Kiki,

Unfortunately, Giro does not sell a transition lens/shield for this helmet.

If you have any further questions feel free to contact me at bcrum@backcountry.com

It sure got a lot of attention between SF and LA on last week's AIDS/Lifecycle ride - worked REALLY well! Visor was great to have on the windy days and really left me feeling less fatigued when it came to dealing w/sand, dirt, winds and blazing sunshine! Photo Credit: mattkurvin.com

Can i convert my regular gir air attack to shield?

Responded on

No...there is a molded indent at each magnet location. If you simply glued magnets to the front of the helmet there would be a large gap between the helmet and shield. The metal on the shield has a rim that locks into the indent at each magnet.

is the shield polarized?

This was a great helmet! I bought this helmet for the 2014 racing season. I loved for the early year cold weather crits. It even seemed to be pretty comfortable in hotter conditions like at collegiate nationals this year. I'm positive that it saved me some watts. However, I believe the most overlooked feature of these helmets are their ability to protect. I crashed into a car recently, and this helmet took the majority of the damage and completely saved me. Thank you giro for great engineering, and I will definitely buy another!

Helmet Head, good or bad?

  • Familiarity: I've used it several times

Seeing as I don't see many people ever wearing this helmet on the road, especially with the visor, I don't know if I like looking like a futuristic bug or not. It does vent very well in hot weather and the shield is very cool, works to keep my contact lenses from turning into crackly crisps, but I guess you gotta have balls to go Tron in public. Ah well, who cares what people think?! I'm head to toe in spandex anyways...get this helmet!

The shield....does it hold fingerprints like crazy....

Responded on

No fingerprints. It's easy to grab it by the edges when moving on and off.

shield colors

  • Familiarity: I've put it through the wringer

When Are other shield colors going to be available?
Otherwise, this helmet is the best thing since sliced bread. I've ridden it in hot/dry and hot/humid weather and ventilation is zero problem. Don't know about "aero" but it's far and away the most comfortable helmet I've ever ridden!

i would love to see them partner with oakley , i won't leave my oakley glasses and i don't like the lens colors they offer (giro) but put them together,
