The Aether MIPS combines airy, open design with a revolution in rotational energy management to advance head protection for cyclists. Inside the Aether, a dual-density EPS foam liner helps to manage a wide range of impact energies, while also boasting deep internal channeling to provide cooling airflow. Our proprietary MIPS Spherical technology is integrated between the layers of EPS foam instead of against the riders head giving riders the benefits of MIPS without any obstruction to comfort or cooling power. Outside, a sleek 6-piece shell forms a stunning silhouette around the massive vents, which get added structural reinforcement via a shatter-resistant AURA reinforcing arch. The final touch is our Roc Loc 5+ Air fit system, featuring 3-way fit tuning, that allows easy adjustment in seconds for the ultimate in comfort.Specifications:Construction:- In Mold Construction With Eps Liner And Progressive Layering- Six-Piece Polycarbonate Hardbody Shell- Aura Reinforcing Arch- Installation: Secure, Tool-Free Mount Fits 22.2mm–34.9mm Seatposts- Vents: 11- Fit System: Roc Loc 5+ Air- Ventilation: Wind Tunnel Vents With Internal Channeling- Certification: Cpsc Bicycle Technology: PROGRESSIVE LAYERING:- The Aether utilizes multi-density EPS foam to save weight and manage a wide range of impact energies.NANOBEAD EPS FOAM:- To acheive a sleek and slim silhoutte without compromising protection standats, the Aether utilizes a micro-bead expanded polystyrene.ROC LOC® 5+ AIR FIT SYSTEM:- In addition to retention adjustment on the ergonomic and compact dial, riders can adjust vertical positioning and tune the contact points asymmetrically.MIPS® SPHERICAL:- A reimagined version of the MIPS® Brain Protection System that eliminates the plastic slip plane of the original MIPS design.IN-MOLD CONSTRUCTION:- In-Mold Construction fuses a tough polycarbonate outer shell with the helmet´s impact-absorbing foam liner. The fusion process allows for better ventilation systems, making in-mold helmets lighter and cooler than traditional helmets.Giro helmets are developed utilizing our proprietary Wind Tunnel ventilation system. This elaborate design combines active vents in the helmet´s shell with exhaust channels inside the helmet that thrust fresh, cool air over and around the rider´s head while forcing heat and stale air out. It´s the most effective cooling system available, and a difference you can feel every time you ride.NANOBEAD EPS FOAM:- To acheive a sleek and slim silhoutte without compromising protection standats, the Aether utilizes a micro-bead expanded polystyrene.ROC LOC® 5+ AIR FIT SYSTEM:- In addition to retention adjustment on the ergonomic and compact dial, riders can adjust vertical positioning and tune the contact points asymmetrically.MIPS® SPHERICAL:- A reimagined version of the MIPS® Brain Protection System that eliminates the plastic slip plane of the original MIPS design.IN-MOLD CONSTRUCTION:- In-Mold Construction fuses a tough polycarbonate outer shell with the helmet´s impact-absorbing foam liner.
