Product Description

Product Description

Superior technology, Tour de France proven performance and leading style are why riders like Armstrong, Petacchi, and Freire count on the Atmos. If you want the absolute best helmet for the speed and thrill of wide-open roads, this is the one for you

Amazon.com

The Giro Atmos bike helmet continues to set the standard for high performance, matchless style, and comfortable fit. The Atmos offers such features as a proprietary in-mold design that provides the strength to support 26 cooling vents, a benchmark in-mold roll cage, and a low-profile silhouette. The vents are particularly comforting, as they work in tandem with an intricate network of internal channels to create a cooling system dubbed Wind Channel ventilation. The upshot? The Atmos is one of the coolest helmets around, making it a top choice for road, 'cross, and XC riders alike.



The helmet's Wind Tunnel ventilation thrusts cool, fresh air over and around the rider's head.
Ionos Technologies
The Atmos employs a number of advanced Giro technologies. The Atmos' in-mold construction, for example, fuses the helmet's outer shell with the impact-absorbing EPS liner. Not only does this reinforce both layers, but the "exoskeleton" allows Giro to engineer helmets that are lighter, more durable, and better ventilated. This culminates in the helmet's proprietary Wind Tunnel ventilation system, which combines active vents with internal exhaust channels that thrust cool, fresh air over and around the rider's head while forcing heat and stale air out. By definition, a channel is a route through which anything passes or progresses. In the case of Giro helmets, the internal channels are carefully crafted and are one of the keys to a well-ventilated helmet. This significant increase in air channeling makes a difference that riders will feel immediately.

Reinforcement and Fit
The Atmos also includes a roll-cage reinforcement--a tough web of DuPont nylon molded inside the helmet's EPS foam liner. This reinforcement provides an extra measure of strength and integrity that you'll never even notice--unless you need it. Finally, the Atmos helmet is engineered using Super Fit technology, making it so comfortable that it virtually disappears when you put it on. The proprietary three-size Super Fit system is based on "human scale factors" data and nearly 20 years of crafting helmets for the best riders in the world. The result is a helmet that fits 98 percent of the world's population, yet looks and feels like it was made just for you.

The Atmos helmet weighs only 275 grams and complies with U.S. Consumer Product Safety Commission's safety standards for bicycle helmets.

Helmet Tips
You should always...

  • Wear a helmet when you ride
  • Wear your helmet low to protect your forehead
  • Fasten your buckle and tighten your chin strap
  • Check your adjustments every time you wear your helmet
  • Inspect your helmet regularly for signs of wear or damage
  • Wear a helmet designed for your activity

About Giro
Working late nights in his garage, designer/bike racer Jim Gentes created the first lightweight adult cycling helmet in 1985. Friends at NASA helped him tune the final helmet shape and vent placement, resulting in the Giro Prolight, a helmet that was better looking and better fitting than traditional designs yet still met the industry's toughest safety standards. Plus, it was half the weight of traditional helmets. Since then, Giro has advanced its helmets, many of which have set the standards for styling, function, and innovation for progressive, performance-oriented riders on dirt, pavement, and snow. Giro helmets are worn by millions of riders, cyclists, skiers, and snowboarders around the world: young bloods and old-timers; hardcores, heshers, and hipsters; rookies, experts, and a few regular Joes too--in fact, pretty much anyone that appreciates superior fit and function, cutting edge styling, and the very best ideas you get in a helmet. Giro is based in Scotts Valley, California.

I won't go into comfort- it's as comfortable as any helmet I had before. I won't go into aesthetics... those are self evident. What I will go into is what happened to me September 18, 2011.

I was riding my bicycle on Mount Evans, the highest paved road in North America. During my descent, the winds became unusual (and I'd ridden this mountain MANY times). Perhaps a thermal eddy, maybe something else. All I know is on a straight section I was fighting a headwind, and then I wasn't, with a curve coming up fast. the winds had reversed direction, causing my speed to go from 30 MPH to 50 MPH in seconds. I tried to slow, but began to skid, so reduced pressure to my brakes to maintain proper control. I couldn't slow enough. I left the road... and fell off the mountain, landing on granite boulders 30 feet below.

Ultimately, I sustained 9 spinal fractures, 3 in my neck and 6 in my upper back. My rib cage and right scapula were shattered. Both lungs were punctured and I came as close to losing my left kidney and my spleen as anyone can come w/o losing them. My head... even though I landed on my head & upper back... escaped with a concussion. My helmet was completely destroyed. My Atmos saved my life in an accident that by all reckoning ought to have killed me. Moreover, I'm walking, and even starting to get back on my repaired bicycle!

In 20 years of road and mountain biking I've had 3 Giros, 2 Bell, and 1 Louis Garneau helmet. This is hands down my favorite. It's the lightest and breathes the best. Even on a recent ride in 94F / 65% humidity / Sunny, my head didn't feel hot. (well, hotter than the rest of me, it was a pretty brutal ride to be honest)

It's super light and very comfortable. You barely feel it on your head.

The reasons I knock it down to 4 stars:

1) Pads are quite sparse and in particular they don't cover the forehead very well. There's also a gap in the center. For me this means that sweat runs into my eyes - as it evaporates it's not sweat but concentrated salt water. Ouch! (Other helmets I've had with larger forehead pads delay this issue. There are head bands on the market for this exact issue, however)

2) The rear plastic head straps are covered in a rubber coating, which cracked within a month or two - doesn't affect the function or comfort as there is a stronger plastic material underneath, but a disappointment given the price.

3) On the underside there are 3 small areas where the foam is melted or looks like it was attacked by a solvent - surface defects really, and you never see it. Doesn't affect function or external appearance but at this price I guess I expect more.

My helmet was from 2008 when they still included a rigid carry pod. Apparently they don't make this anymore, which is a shame since it is a super nice feature - protect your helmet, carry your gloves, Gu and Powerbars too (It was well ventilated so things don't get stinky). - you can still get them on Ebay though...Specialized now makes one too but the Giro one looked nicer.

I always rode as a young girl on my bmx bike, down stairs and through the streets, with no helmet. It was the early 80's and no one wore helmets... As an adult I went for a while riding without one, but ultimately, we all know it's something we should do. Having someone in my family sustain brain injuries REALLY drove that point home.

This helmet was way more money than I wanted to spend on a helmet but it's the ONLY helmet I've ever tried on that felt, well, barely there.... You can easily forget that you're wearing it, which is what I was looking for. After all, I wanted to use it every day, not spend $50 on a helmet I hated and would never wear. The atmos also leaves your senses intact... I sometimes feel like my hearing or quickness of response would be influenced when I try on a bulky hemet. I DO use it all the time and will buy another once mine gets too old. Also, having a smaller head, most helmets look awful on me, like I was attacked by fungus and turned into a mushroomhead. The atmos tapers nicely around the edges which looks way better.

The adjustment on the helmet is great and easy, plus the straps stay in a good spot and you can adjust their angle too. The only tiny thing I'd change is the same thing an earlier reviewer noted... where the helmet meets the very top of the head is a little bit flat for my head, so there is small contact point there that I wish weren't there. Aside from that It's perfect and thanks Giro!

I commute as year round as I can in Chicago, so in the winter I just slap on a helmet cover over it and a thinly knit hat underneath and it becomes amply warm enough.

Lastly, the most glowing Giro helmet recommendation probably comes from Wisconsin.

First thing is that this helmet works for its most important feature: to protect your noggin. I crashed coming down a mild hill in July and Jim Kirk shoulder rolled onto the payment. I was going 28 mph and hit a road hazard so I impacted very hard. My shoulder hammered the pavement along with the side of my head and I sustained NO head injuries or any kind of temporary mental fog or spaciness. Unfortunately my collarbone broke really bad and now I have more titanium in my body than on my bike :-) The helmet was cracked in 5 places on the interior foam too, so clearly it did what it was designed to do.

Now onto the other features, less important but still worth considering. I bought this helmet because my previous Bell helmet was way too hot and I needed more airflow. It was a definite improvement, but my bell was about $40 and this cost $130. It was in no way $90 worth cooler. Still, my head is more valuable so I can't complain. Also, when I looked at the higher end cooler ones they obviously have to remove foam and hence protection so I think this is a good trade-offf between price, performance, and airflow. Otherwise it is very comfortable and light, lots of adjustments to tweak the fit, and the only issue I've had is the rear adjuster tabs for the head size seem to slide off. They are more or less aesthetic only and the helmet stays adjusted, but for the price I was a little disappointed - until it saved my life. So for the price and cheesy tabs I knock it down 1 star.

I found out that Giro will give 30% off on a replacement helmet, so that is pretty cool support too.
