The Aether MIPS combines a lightweight, 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 much of the impact energy, while deep air channels provide outstanding cooling. The independent MIPS Spherical technology is integrated between the two EPS layers, offering the safety benefits of MIPS without compromising comfort or ventilation. On the outside, a sleek six-part shell forms an impressive silhouette around the generous ventilation openings, which receive structural reinforcement from the shatterproof AURA Reinforcing Arch. Completing the design is a Roc Loc 5+ Air fit system with 3-D adjustment for ultimate comfort and quick adjustability.
