The Giro Men's Aether MIPS Cycling Helmet 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. The proprietary MIPS Spherical technology is embedded between the layers of EPS foam instead of against the rider'’s 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-proof “halo” that runs throughout the helmet. The final touch is the Roc Loc® Air fit system, featuring three dimensional fit tuning, that allows easy adjustment in seconds for the ultimate in comfort.
