What Our Gearhead® Experts Are Saying:“The Cyrius X has quickly become a shop favorite because it eliminates the guesswork—no swapping lenses or stressing about changing light. The REACTIV lens adjusts on the fly, and the frameless design gives you a massive field of view so you can focus on the line ahead instead of what’s on your face.”Whether you’re skinning at dawn or chasing last chair laps, the Julbo Cyrius X REACTIV Goggles keep your vision sharp from first light to flat light.

Anti-fog construction, dual-pane ventilation, and plush dual-density foam keep comfort locked in all day. Topped off with recycled materials and a modern strap that’s helmet-ready, the Cyrius X delivers performance you’ll feel every run.
