The Giro Atmos continues to set the standard for high performance, matchless style, and comfortable fit. Its low profile silhouette, 26 Wind Tunnel vents, and benchmark in-mold Roll Cage make it a top choice for road, cross, and XC riders alike.
- In-mold Composite Reinforcement - fuses the helmet's outer shell with its impact-absorbing EPS liner during the molding process, making the liner literally a part of the helmet. This fusion process reinforces areas around vents and ribs, creating a one-piece 'exoskeleton' that allows the helmet to be lighter, more durable, and better ventilated than traditional designs
- Roll Cage - a tough web of DuPont ® Nylon® molded inside a helmet's EPS foam liner.
- Construction: In-mold - EPS liner, polycarbonate shell
- Fit System: Roc Loc 5
- Easily dial-in both fit tension and adjust vertical position with a single hand. Just twist the dial for a tighter feel on rough 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 nearly 40-percent lighter than its popular predecessor, Roc Loc 4.
- Micro Dial: The heart of 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.
- Three-Position Bracket: Ffeatures 15-millimeters of up/down movement. Like the Micro Dial, this system can be adjusted without removing the helmet. Carefully-crafted ergonomic arms are shaped to be as comfortable as possible.
- Dual Pods: These two panels are designed to firmly grasp the back of your head while comfortably cradling the occipital lobe.
- Strap Baskets: With Roc Loc 5, your helmet straps are always right where you need them. Not to mention this strap basket brings a new level of comfort.
- Ventilation: 26 Wind Tunnel vents, internal channeling - combines active vents with internal exhaust channels that thrust cool, fresh air over and around the riders head-while forcing heat and stale air out
