The KLIM Aeon Goggle is engineered to create optical perfection and clear vision through the most extreme conditions. KLIM&&';;s toric lens shape closely matches the human eyeball shape, meaning virtually zero optical distortion along with phenomenal peripheral vision, which both result in reduced rider fatigue. The Aeon lens system uses a high-speed magnet+hinge lock that makes swapping lenses extremely fast - without even removing your gloves. The Aeon is engineered with extreme anti-fogging technologies including air circulation through full-frame foam filtered vents, massive internal air volume and Super Anti-Fog lens coating.
