The Giro Athlon Mountain biking helmet crushes the racecourse with speed and style – and features the new Roc Loc 5 fit system. After more than ten years of refinement, this ground-breaking fit system provides an entirely unique use experience with an unmatched level of comfort, stability, adjustability and weight savings. With Roc Loc 5, you can easily dial-in both fit tension and adjust vertical position with a single hand. Just twist the dial for a tighter feel on tough terrain, then back it off a notch and relax across the flats or a warm climb. Even with these remarkable features, Roc Loc 5 is still 40-percent lighter than its popular predecessor, Roc Loc 4. Roc Loc 5 systems is: 1) Micro Dial. The heart of the Roc Loc 5 is this ratcheting, micro-adjusting dial. A simple, two-finger twist of the Micro Dial opens or closes the retention system and each click is audible. 2) Three-Position Vertical Fit – It's never been easier to change vertical positions and fine-tune fit. We incorporated a three-position bracket that features 15-millimeters of precise up/down movement. Like the Micro Dial, this system can be adjusted without removing the helmet. 3) Carefully crafted ergonomic arms are shaped to be as comfortable as possible, yet work flawlessly with Giro eyewear (what we call Super Fit engineering). 4) Dual Pods – These two panels are designed to firmly grasp the back of your head while comfortably cradling the occipital lobe. Strap management – with Roc Loc 5, your helmet straps are woven through the fit system, so they are always in the perfect position. Complex Internal Design – Dozens of small parts work together seamlessly to provide exceptionally user-friendly adjustment. Minimal and Light, yet Strong – Although this fit system is 40% lighter than its predecessor, it's much stronger. In testing, Roc Loc 5 performs flawlessly, even after 6,600 cycles (equivalent to 3 years of riding with 3 round trips per day).

Customer Reviews
Great Helmet …
From searching for hours for a helmet, I found Giro to be a leader in helmet design. I liked the look of the Athlon from the start. If you have a dealer near you, I would highly recommend trying on before buying. I saved $30 buying from Amazon, & love the helmet.
The adjustments are very easy to make, and I am rarely aware that I’m wearing my helmet. Very light/comfortable, & would recommend to a friend.
Love It!
OK so pretty much all helmets are the same in my opinion when it comes to protecting your head. I like this helmet because it is very comfortable. This is my mountain biking helmet so it is heavier than a road helmet but still comfortable. The helmet is very cool and fits nicely. It is very secure feeling and several steps up from my Trek Vapor helmet. I have a Giro Prolite and Ionos helmet and Giro makes a quality helmet.
Incredible!!!
Love this helmet. A nice uprade from the Bell I had before. Fits snuggly, loved it came in different sizes so I picked a really good fit.
Good!
Is a good helmet, comfortable and easy to adjust.
Just did not like the logo and brand are stickers, easy to unglued.
Awesome
Great look, light weight and comfortable. Runs a little large. Had to return the first helmet to get a smaller size. There are many ways to adjust the helmet so you can get a great fit.
great helmet
Great looking helmet. I have a small head and have trouble buying hats that fit me without making me look funny. This helmet fits like a glove. The flames add a little funk and make the helmet look way cool. All my cycling buddies love the way it looks. It is super light, can barely fill it on my head. Even though it was a couple of dollars more on Amazon, decided to by it here and get the worry free customer service. Woulf definitely recomend to a friend, hopefully they would get a different color.
Great Helmet
This is the second time I have purchased this helmet. I ride both on road and off road and I like this helmet for both. The only reason I am on helmet #2 was a minor crash in the Ocala National Forest and the helmet protected me very well but the tensioner adjuster in the back did not survive the impact.
Great Helmet
Bought this helmet after hearing good things about it from a frined. I have used it for 6 months without problems. Thankfully no crashes to test it out. I use it for both mountain and road biking. No issues with quality.
