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