The Aether MIPS is Giro’s brand new flagship helmet which is designed with an airy and open design that brings a revolution in rotational energy management to improve head protection for cyclists. Inside the Aether is a dual-density EPS foam liner which helps manage a wide range of impact energies, with deep internal channeling to provide cooling airflow and keep you comfortable while you’re out riding.

Unlike other helmets, Giro’s proprietary MIPS Spherical technology is integrated between the layers of EPS foam instead of against the rider’s head, giving you the safety and peace of mind that comes with MIPS, without reducing comfort or air flow. While the stunning shape of the Aether MIPS is formed by a sleek six-piece shell that surrounds a series of large vents, with added structural reinforcement from a shatter-resistant AURA reinforcing arch. The final touch is Giro’s Roc Loc ® 5+ Air fit system, featuring 3-way fit tuning that enables you to easily adjust in seconds. This is Giro’s flagship helmet for a reason, it packs all of their most innovative technology and design into one lightweight, safe and well-ventilated helmet that is the Aether MIPS road helmet.
