The Julbo Liry Kilian Jornet Series is built for sustained effort in exposed environments—where clarity, airflow, and stability are non-negotiable. Its wraparound architecture creates a wide, uninterrupted field of vision while shielding the eyes from wind, debris, and high-angle sunlight.
At the core of its performance is a ventilated frame system that actively manages airflow. Strategic front venting, paired with a suspended lens design, allows heat to escape before it becomes fog—maintaining optical clarity during high-output movement like trail running, cycling, or long alpine pushes.
Fit is highly tunable. The 3D Fit Nose Evo system adapts to the contours of the face, while CustomFIT temples can be micro-adjusted for a locked-in feel that remains stable across uneven terrain. Grip Tech inserts add friction without pressure, ensuring the frame stays secure without becoming distracting over time.
Constructed with Rilsan® bio-based material derived from castor beans, the frame balances low weight with resilience and flexibility. Paired with a Spectron 3 lens, it delivers consistent sun protection and impact resistance in bright conditions—making it a reliable tool for fast-moving days in the mountains and beyond.
