The Aether MIPS combines airy, open design with a revolution in the management of rotational energy. This makes it an innovative head protection for cyclists. Inside, two interlocking shells of EPS foam absorb most of the impact energy, while deep air channels provide superior cooling. Standalone MIPS Spherical technology is integrated between the two EPS layers - rather than directly contacting the head - to deliver the safety benefits of MIPS without compromising comfort or ventilation. On the outside, a slim six-piece shell forms an impressive silhouette around lush vents, with structural reinforcement from the shatterproof AURA Reinforcing Arch. The finishing touch is a Roc Loc 5+ Air fit system with 3-D adjustment for ultimate comfort with split-second adjustability.
