Product Description
Classic performance!

Legendary design, performance and comfort. The Atmos II with SL Roll Cage inner reinforcement allows large ventilation openings without sacrificing light weight and safety. This isn’t the only reason why it remains as coveted as ever by riders across the spectrum: Racing cyclists, mountain bikers and triathletes have made it their number one for training and competition. The reason for this isn’t just its excellent wearing properties combined with extreme stability, but also the sensational Roc Loc 5 adjustment system, great ventilation and its very low weight.


In-Mold Construction
With In-Mold construction, the robust polycarbonate outer shell is bonded to the EPS inner shell in a single operation during foaming of the impact-absorbing EPS inner shell. The helmet becomes, without extra weight, even more resistant. This production process also makes it possible to form much better ventilation systems and openings. In-Mold helmets are, compared to traditional helmets, lighter and have significantly better ventilation systems.

Super Fit Engineering
The Super Fit sizing system is the basis of Giro's product design and development process. Giro's many years of experience make it possible to access an enormous amount of measurement data of the most diverse head and face forms during development. After the most varied and intensive tests in Giro's laboratories, the product is subjected to further hard practical tests and put through its paces by Giro's team riders, who then optimise it until the maximum fit and comfort is achieved. Of course, Giro doesn’t compromise on quality and functionality - this is what Giro understands by Super FitSystem.

Roc Loc 5 Fit System
The new benchmark for fitting systems is without a doubt the Roc Loc 5 fitting system. The adjustment mechanism is in a mini housing. The size adjustment is easy and in micro grids with two fingers. Additionally, the system can be adjusted in height so that a perfect fit of the helmet is guaranteed.

X-Static is a pure silver fibre. It is antibacterial and thus fights odour-forming bacteria. Its heat-reflecting and heat-shielding properties provide a pleasant climate and increased comfort.

Therformed SL RollCage
The Thermoformed SL Polycarbonate Roll Cage is 49% lighter than conventional composite reinforcements, offering outstanding stability. Thanks to the new SL Roll Cage, 15% less compressed EPS foam can also be used, which in turn reduces weight without sacrificing safety.

Wind Tunnel Ventilation
Wind tunnel ventilation is Giro's own system of internal ducts and active ventilation openings that direct cool, fresh air over and around your head, squeezing out tiring heat and stale air. A difference you can see and feel - on every ride.
