While we're not prepared to claim that the aerodynamics of Giro's Air Attack Shield Helmet is enough to make the difference between a podium and an also-ran, the wind tunnel-tested design certainly can't hurt your changes. This year's updated version continues to offer many of the same lightweight, efficient features as the previous versions with the addition of a redesigned shield to further improve its drag-shedding capabilities. The polycarbonate Flash shield, produced by Carl Zeiss Optics, serves to redirect air flow and keep your eyes protected and vision clear at high speeds. Post-race, it can be flipped up or unfastened entirely using its magnetic clips.

An In-Mold polycarbonate shell provides structural integrity to the Air Attack Shield's EPS foam body, diffusing impact in the event of a crash. For added comfort, Giro includes removable X-Static padding, which works with the Roc Loc Air fit system to ensure the helmet has a secure, streamlined fit. Six vents and internal channeling ensure that aerodynamics don't come at the cost of stifling heat by allowing for plenty of cooling airflow.

  • Removable Carl Zeiss Flash shield with magnetic clips
  • Roc Loc Air fit adjustment
  • X-Static padding
  • 6 vents

Apprehensive 😬

Wasn’t sure about this purchase, but after reading some mixed reviews and doing some research I went ahead and pulled the trigger since it was on sell for half price. And Wow 😲! Sure glad I did went on 30 mile ride in 85 degree heat and what they say about the cooling affect the suspended cage & channels generate stands true. Plus I loved the shield also! So I’m giving it πŸ‘πŸ‘πŸ‘πŸ‘

Love the integration

I have a peanut head so I ordered the small. It just fits, so all is good there. I love the integrated wind-screen/lense. I was getting sick of wearing glasses because the helmet strap interferes with glasses' arms. Not a problem here. And when you stop riding and want to remove the lense, it just flips and reattaches to the helmet -- brilliant! No more fiddling your glasses into the helmet air holes.

Great for Cold Weather Riding.... LOL

The lack of vents makes it a great helmet for riding in Temps below 35 degrees F.

I had the original air attack. Then I had a pretty bad fall on the road. The helmet did its job and took the hit. Got a pretty good scratch on the top, but my head was totally fine. I picked up the replacement helmet which is the air attack with shield. I wear glasses and hat putting on sunglasses. This takes care of everything. Good to know that the additional lenses are inexpensive at $24 on amazon. I picked up an orange lens for my white helmet.

Great Helmet!

I wear this helmet pretty much every day for my commute into work. The helmet is comfortable; the straps and roc loc 5 fit system are easy to use and keep the helmet snug against your head. The shield (sun protection) works really well so you do not have to wear sun glasses and as an added bonus it helps keep your eyes free from rain and splash from the road. I was looking at helmets half the price of this one, but I am really glad I got this helmet!

Love It!

    Love this helmet! I've always been uncomfortable wearing sunglasses under my helmet and this solves that problem, plus it's very comfortable.
    On another note...the customer service at Backcountry is amazing!

    nice helmet

    i was a bit worried about it being too hot but it hasn't been a problem riding at about 35+ celsius :)

    Great triathlon helmet!

    I recently picked up one of these because of how much I liked the non-shield model. I haven't competed in any races with it yet but hope to do so this coming spring. All the same features apply! Great adjustable fit with the Roc-Loc Air. Better than expected ventilation. Now having the option of a shield is fantastic! Simply flip it around when not needed and it is safely and and conveniently stored out of the way.

    The slippery slope of aero vs. venting

    • Fit: True to size

    Ive owned the base and shield helmet for two seasons and only made it a point to wear it all throughout this past summer in Houston TX. I was sold on it after noticing the reduction in wind buffeting and noise when you have your head down and forward. The complaints of it being a hot helmet are well founded. This helmet exacts its pound of flesh if you do not present it with the conditions required for it to perform as it was designed. If you're out front, and in the wind, with active airflow, this helmet breathes great. You can, and will feel the air go over your head inside. If you're living in the draft of a pace line, it negates all the engineering put into this helmet and you're left cooking your skull. Ventilation of the shield version against the base is negligible at best. The vents where the helmet meets your brow are meant to buffer against your face and then use the four vents on top to draw fresh air in and over. They're mostly effective, but not nearly as much as when you've got your head down and forward. I've worn it on multiple competitive centuries in temps well above 98F and was never any more uncomfortable than expected. The fit and finish are as well as any other upper end Giro helmet. Some people balk at the aesthetics, which I will agree, do take some time to grow on you. I find it interesting as this helmet is constantly compared to the Evade. Riding friends swear by that helmet, but also have the same complaint about it being a very hot helmet. I find that interesting as the number of vents is much higher than the Air Attack, so one would guess, more vents is much cooler. Perhaps that helmet needs the same conditions of the Air Attack as well. If you can stand the pain of living in the front and bringing the hurt to all behind you, at least be confident in the knowledge that your head will be quite cool, as well as the bit of effort saved from the aero benefits netted by the helmet itself.

    This helmet just saw my partner through a windy, relatively climb-heavy bike leg at Ironman Ceour d'Alene. She beat her target splits and entered T2 feeling a lot fresher than other competitors. I'm not sure how much the helmet actually helped, but every little bit can make the difference over 112 miles.

    She also uses it for everyday road riding and training. The relative lack of vents hasn't given her any issues in Northern Utah's 100 degree summer.

    My favorite "go-to" helmet

    This helmet has solved the problem I had with sport glasses. My eyewear prescription is *co$tly* to order sport sunglasses...I wanted to wear my own glasses and this shield helmet allows this. Snap on the magnetic shield and I can comfortably wear my glasses behind the shield. The helmet is super comfortable - I chose the Neon color to be visible and it matches my shoes (Gaerne carbon) Its also not hot at all in the summer, given the vent area.

    There is some wind noise, but not more than other helmets in my experience.

    How much clearance was there between your prescription glasses and your sheild? Ive been looking for a helmet that i can wear my everyday prescription glasses and still have the effect of sunglasses with an aero body.

    Great helmet

    I have a few of these same helmets due to different homes, bikes and accessories. I really like the look, fit and functionality, really like the shield which does not require I wear separate bike sunglasses. Great matte white, orange and fluo yellow colors.
