Sizing Information for Giro Helmets:

Giro Helmet Sizing Chart

Absolutely brilliant helmet, had the original when it came out many moons ago. Quite a compact helmet, limits the mushroom head effect! Brilliant airflow as well, due to large vents. The new rocloc system is very good as well, easy quick adjusting if you like to wear a buff on cold days under your helmet.
Great quality helmet, light and the fit is great. Fast delivery and great price!
This is my second Atmos. The first lasted seven years and was an excellent combination of fit and ventilation. The newer version has an improved rear tensioner and I was able to take it out of the box and adjust the fit within seconds. Recommended
Superb all round helmet, super light weight and a great fit is enabled by giros roc lock system. Ace
Very good fit. Comfortable during extended use ie 10hr alpine epics. great ventilation for those >25deg C days. why pay more...?
Good ventilation with good fit. Construction seems of high qaulity. The straps are a pain to adjust and the helmet still feels to loose for ultimate safety - perhaps this is less of a focus on road helmets? Once the straps are adjusted to the most secure fit they slip out of place again quite easily. Not realy what you expect from a qaulity brand at a high price like this. Still a good product but expectations were higher prior to purchase.
Fitted my head better than the Kask - excellent helmet. The matte black version does absorb a lot of light - perhaps go for white if you're doing a lot if urban riding.
This is my third Atmos. It was ordered to replace a helmet damaged in a collision with a car. I landed on my head and was knocked unconscious. I firmly believe that helmet saved my life. The Atmos fits me well, it is lightweight and extremely well vented, the roc-loc 5 retention system is excellent and the helmet is, in my opinion, the most stylish around. The price was the cheapest I could find and delivery from Merlin was super fast, as always. 5 stars all round!
After a Giro saved my life/marbles the week before (an over-the-handlebars at 5mph, but temple-first onto paving stones), I had a certain brand loyalty towards the marque. I upgraded to Atmos, and it's a really classy piece of kit. Very lightweight and aero, it looks very cool indeed. In fact, I'm sure it would be cool on a climb in Summer - you'll need a skull cap through the Winter). Merlin's discount made it affordable (just), with speedy delivery.
I like it! It's light (my size medium was 248g) and fits well like all Giro helmets.
Only used a few times so far, the Atmos helmet is extremely light and comfortable. The helmet is vented well and is noticeable on very hot days.
Great helmet, fits better than the Monza I upgraded from. Great price too.
I bought the Giro Atmos helmet as a replacement for my Giro Monza helmet as the Monza looked massive on my head. What an improvement! The Atmos is light and sleek and the added ventilation helps on long warm weather rides. I certain have not regrets with this product and Merlin Cycles service was outstanding with super quick delivery, I'm 100% satisfied.
Great helmet, very comfy and light. Excellent price and fast delivery.
great service,fast delivery,helmet is superb but then its a giro so cant go to far wrong.
I've been wearing this helmet for a week now on fairly long rides. I like it a lot, it's well ventilated and very light I don't notice I've got it on at all. It's very easy to set up and the RocLoc 4 which sets the size doesn't back off or loosen like a few other helmets I've worn in the past. I would definitely recommend this to anyone looking for a new lid they don't come much better for the price. Another hassle free purchase from Merlin Cycles,great service as usual.
Awesome stuff and at a great price too! This helmet is the best helmet I've worn and I've worn a few in my time! If anyone is looking at getting a new helmet I recommend this atmos it's excellent!
When buying cycling products I always cross check prices with Merlin. Merlin always wins. Shipping consistently takes 10 days to the states which is more than adequate for free shipping. Merlin always has its products out the door very quickly, the rest if the time is international carrier delay. As for the product, very happy with the fit. Snugg, light, and well ventilated. Doesn't look like a mushroom on your head like the Saros.
