Performance, style, and comfort. The Atmos II uses the reinforced Thermoformed SL Roll Cage, a breakthrough in helmet architecture that allows great ventilation without compromising its integrity.

Main features:

• Molded polycarbonate shell with EPS liner for maximum impact absorption
• Thermoformed Roll Cage reinforcements: ultralight fused polycarbonate internal skeleton that acts as a second structure, improving shell support and increasing strength
• X-Static interior: 100% pure silver multilayer fiber that is permanently bonded to the fabric surface. This reduces odor and regulates heat
• Roc Loc 5 adjustment system: allows easy one-handed helmet position adjustment. The rotating dial lets you perfectly fit it to your head. It is also 40% lighter than other adjustment systems and offers comfort, stability, and unmatched adaptability
• Wind Tunnel ventilation system: 26 vents providing a channeled ventilation system tested in the wind tunnel (exclusive to Giro)
• Slimline buckle closure
• Weight: 190g (size M)
