Naos Ziris Photochromatic

Adapts well to changing light. The photochromic lens automatically reacts to sun, shade, and clouds, meaning you don't have to switch lenses as often during long runs or rides. This feels reassuring and practical, especially on trails with a lot of variety.

Remains breathable during intense exertion. The open frame allows plenty of airflow, meaning the glasses fog up less quickly during climbing, tempo runs, or warm weather. At the same time, the field of view remains wide without much distraction from the frame around the lens.

Works particularly well during long sessions with changing conditions. During wooded sections, open gravel roads, or changeable mountain weather, you will notice that the clear vision and low weight help you stay focused without constantly adjusting your glasses. That comfortable wearing sensation remains pleasant, especially when you start to fatigue.

Undecided between an open performance goggle and a closed shield model? Choose the Ziris if ventilation, versatility, and low weight are more important than maximum protection against wind or splashing dirt.
