    Sometimes the sequel is better.

    It’s a big job to take on a sequel, but Giro knew that the Atmos was getting a little long in the tooth, despite its massive worldwide popularity. So, it took what everyone loved about the original Atmos (the light weight, comfort, and ventilation), and packed it full of new technology. The biggest change is the inclusion of the SL Roll Cage, a thermoformed structure that provides the frame for the EPS foam. The SL Roll Cage prevents the helmet from breaking apart in an impact, so that it can do a better job of protecting your head the way it was designed to do.

    • Roc Loc 5 adjustment system
    • 26 vents with exhaust channels that lead the air over the head and out of the back of the helmet
    • X-Static pads inhibit bacteria growth

    One bad flaw, IMO

    • Familiarity: I've used it several times
    • Fit: True to size

    I had read nothing but good, no great, reviews on this helmet and decided to get one while they were on sale. I have always had Giro helmets and was expecting good things. However, there is one flaw in this helmet that I am surprised I have not heard about. In the middle of the forehead, there is a gap without a sweat pad (the pad is two pieces - a right and a left). Because of this, sweat just pours right down the middle of my head and down my nose. I had to go to a Halo headband which is OK but it only moves the problem to later in the ride. Other than that, great helmet. I will be moving to one of the new MIPS helmets later this year.

    Light and Comfy

    • Familiarity: I've used it several times

    I love this helmet. It is lightweight and comfortable. With the easy adjust wheel in the back of the helmet, I can snug it quickly to my head and forget about it. It has plenty of vents to keep you cool when things get hot which I am looking forward to in the summer heat, and the helmet itself has a classic and stylish look. I am very glad I ended up getting this helmet.

    One of the best bike helmets ever made

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    I have been riding for nearly 40 years.
    Have used so many different helmets, but, hands down for the protection, style, weight, comfort and fit and, the price, specially, if it is on sale, the Giro, Atmos, helmet, is hands down, the best helmet that Giro has ever designed and created.
    I have been using it ever since it first came out.
    Unless you think about it, while riding, you do not really, "feel it."
    This one is a true classic.

    Given as gift - but he's raved about it

    • Familiarity: I gave it as a gift but have feedback to share

    No sense re-inventing the wheel - right? Gave this as a gift to replace the dad-in-law's nappy old one. Fit, style, use exactly the same as they were before and he's as happy as can be. One of the best things about Giro helmets are how adjustable they are, and the Atmos is no exception.

    Don't even know it's on

    • Familiarity: I've used it several times

    So far i am loving this helmet, super light weight, comfortable on my head to the point where i forget it is there. I don't think there is better helmet for the price, would recommend to anyone looking for a great road helmet.

    Comfy, light and does a great job

    • Familiarity: I've put it through the wringer

    1. Comfy

    2. very light

    3. amazing adjust-ability

    4. does a great job when you land on your head in a crit race - see attached pic

    Comfy, light and does a great job

    Simple does it.

    • Familiarity: I gave it as a gift but have feedback to share
    • Fit: True to size

    Sometimes a helmet is just a helmet. And there's nothing wrong with that. The strap isn't as soft as some, the shell isn't as obnoxiously "aero" as some, and the body isn't as minimalistic as some. It's not the most advanced (read: expensive) helmet, but it disappears once it's on, and that's what matters most. It's a classic for a reason.

    Version II is better than ever

      Giro designs some of the best high-end helmets in the sport (atmos, aeon, synthe). Excellent gloves and aero covers too.

      I purchased my first Atmos helmet 12+ years ago. It was one of the first modern, really good looking, highly-vented, in-mold composite bike helmets made.

      Pros: Very, very well ventilated. Light weight. Strong. X-static (silver fiber) pads naturally inhibit sweat odor. Awesome looks. Affordable $$.
      Cons: none.

      This is a great Summer road helmet. The classic for a reason.

      Note: Make sure any helmet fits your head *shape* correctly (more round or oval). This is very important and true with any company's bike helmet. The only way to know is to try 'em on.

      If it aint broke, don't fix it

      • Familiarity: I've put it through the wringer

      I've been using the Atmos now going on ten years, still my favorite! Great lightweight design, comfortable fit and plenty of ventilation for those hot days in the saddle. I often forget I'm wearing it sometimes. This will be my third one, and I'll probably re-up again when the time comes.

      If it aint broke, don't fix it

      Same great helmet as it was 10 years ago

      • Familiarity: I've put it through the wringer
      • Fit: True to size

      This design certainly isnt new, but it shows how great it was when the original Atmos came out quite some time ago. Great ventilation, solid retention system, a fit that works well for me, and all at a lower price as this helmet has succeeded by others with snazzier options. I also own the Synthe and love it, but if you want the best helmet for your money this is it.

      Great helmet at a good price

      • Familiarity: I've used it several times

      I bought this helmet to replace an older Giro helmet I've had for several years now. The Atmos II is lightweight, better ventilated than any other helmet I've owned, and priced right. The Roc Loc adjustment is great, but I think my head is sized weird - so the medium is too small, but the large is a bit too big. The adjustment system does cinch around my head well - but it still leaves a gap on each side of the helmet and it doesn't feel that secure. The thin straps are unobtrusive but the ends were a bit long - which I easily solved by cutting the excess strap material and singing the ends. The foam on the bottom lip of the helmet is fairly exposed though - so one concern I have is the long-term durability of it.

      So aero bro...

      • Familiarity: I've put it through the wringer

      Although my road cycling helmet is minor I am a guy that owns a lot of helmets! This one ranks right up there in terms of lightweight and breathability.
      Huge vents dump heat when stationary and cranking 30mph it almost gets chilly. While the suspension adjustments are easy to use and very accommodating for wearing a liner or having (my problem) really long hair.

      Sizing was pretty standard for me, I have 5 other Giro helmets all in size large and this one is no different.
      For the money, I am very happy with this helmet. I know there are better but there are also cheaper ones that don't perform as well.

      This Helmet Gets Better With Age!

      • Familiarity: I've put it through the wringer

      I previously wore the original Atmos for about 6 years and absolutely loved it. No doubt I wanted the new model. The Atmos 2 is even better. It vents incredibly well which is important for the hot sticky days here in the Mid Atlantic region. The best upgrade for the new version is the rock lock system. It has a super easy adjustment knob on the back that can be done on the fly. For what is now a mid level priced helmet I can not imagine a better choice.

      Unanswered Question

      Always wore a large, measured my head at 22.75 inches so I ordered a medium. My head fits and everything seems great but I'm freaking out cause it looks to small and the back of my head seems exposed compared to my old $50 trek helmet. Any feedback from users will be appreciated.
      Cheers, Mike T

      How does the matte finish compare to the old Atmos gloss? Any chance "marks up" more easily? Thanks!
