Giro Athlon Helmet -

The Giro Athlon was created in response to their efforts to better the hugely popular E2 Helmet. In Giro's world this is true -- make it better or don't waste the effort. Well, they didn't waste their time. The Athlon betters its predecessor by moving air more efficiently over the rider's head, and its shape has been improved by Giro's attention to "form language."

You shouldn't be surprised. Giro would never release a new helmet that didn't outperform the one that came before it. Even though the vents in the Athlon appear smaller than what you remember on the E2, Giro has improved their internal channeling to move that air over your head faster and easier. There are a total of 23 wind-tunnel-tuned vents for both intake and exhaust.

The Athlon's shape is more in tune with a human head than the E2. This is actually something we'd struggled with when checking out the E2. We liked the vents, the Roc Loc, etc, but the helmet didn't work with our aesthetic sense. It turns out that Giro felt this way too. So the shape is more organic but still has an aggressive quality about it. The Athlon also sits a bit lower on the head which helps it seem to disappear when riding.

The Athlon uses Giro's latest retention system, Roc Loc 5. The advantage over the older Roc Loc 4 is that you can make micro adjustments to the retention basket with a thumb and finger -- simply twist the ratcheting dial to achieve perfection. The whole system can be adjusted up and down to cradle the back of your head just as you like. Some of Giro's forward thinking gave rise to the special shape of the arms -- they allow the use of Giro's eyewear without interference, and they maintain the position of your straps so getting the helmet on is a no-muss, no-fuss affair.

The Giro Athlon Helmet is available in Black/charcoal and Matte White and in three sizes -- small, medium, and large. The visor has 15° of vertical adjustability for optimal protection/visibility, and it's removable as well. The wicking pads are durable, thanks to the welding of the cover material to the pad material, and easy to wash if they get stinky.

Jenson USA (2013)
The Giro Athlon is used by XC racers Adam Craig and the Rabobank/Giant MTB Team and by riders that are looking for a strong lightweight helmet that is comfortable in all conditions. Giro’s Wind Tunnel™ ventilation system is a combination of active vents with exaust channels in the helmet that push cool fresh air onto the riders head and pushing out the warm air that is already inside the helmet. Keeping the head cooler and more comfortable is just the start. For safety, Giro uses an In-Mold reinforced roll cage along with the In-Mold-EPS liner with polycarbonate shell. In the event of a crash, this technology allows the Giro Athlon to maintain structural integrity and offer maximum protection.

Giro uses Roc Loc 5, their best fit system, to fine tune the fit of the helmet with micro adjuster as well as the ability to offer fore/aft tilt adjustment. The interior padding is plush and uses X-Static fabric to combat bacteria and odor.

I have a few Giro MTB helmet and this is the first one with Roc Loc 5 and the are so easy to turn and adjust. I like the Matt Black color and the simple design. It looks nice with and without the visor. The 300g weight is ok for Mountain Biking and you hardly feel the weight. The strap is thin and soft unlike some low end Giro helmet. Since I was my helmet after long ride, cleaning the padding is a little inconvenience. It has 5 pieces and I lost 2 small one. I would recommend them when on sale since it is pricey for full price.

This Helmet is great. I have been using it for a few months now and am very happy with it. It is light and fits great. I had an older Athlon with the RocLoc 4 system and was happy enough with it but the RocLoc 5 system on the new Athlon is definitely more sturdy and better designed. The venting is good and I like the fact that the visor is removable for when I jump on my road bike. All in all it is a great helmet for the price.

Nice looking helmet in the matte finish. Sizing chart is correct. Helment comes packaged with 2 plugs to fill holes if peak is removed and larger pads for smaller head cirumferences. No replacement pads included as with the 2 previous Giro helments I've purchased but this isn't a deal breaker. Great price from Real Cyclist.

My wife loves this helmet. If only it came in a few more colors that were women-specific, it would be perfect, but the fit is nearly as good as much more expensive offerings from Giro and she likes that the visor is there for dirt rides and removable when she's on the road.

This is a good value helmet for racing. I used it for my first Iron Man. The fit adjustment dials in the fit well so the helmet stay put while riding hard.

Great fit and light. Good venting. Giro comes through with a great helmet.

I tried this and the Pneumo. Very similar in lightness, but has more vents.
