Description

The lightest pair in this series, with a wide panoramic lens. You hardly feel it on long runs and it stays put on climbs and descents.

The Reactiv 1-3 lens adapts to the light. You choose between Light Amplifier and High Contrast; both range from category 1 to category 3. You notice that on mountain routes that keep switching between forest and open rock. Ventilation at the front and through the frame keeps the lens clear when you work hard.

Not sure? Choose the Intensity if weight matters most to you. Want more ventilation and side protection, the Fury is a better choice. With a wide face, look at the Faster XL. For snow you need a category 4 lens.

As light as possible in changing light: this is your pair.

Why Julbo?

You start in the dark, run through a shady forest and an hour later you're on a bare ridge in full sun. One pair of glasses that handles all of that saves a lot of hassle. That's exactly why we carry Julbo at Trail.NL.

Julbo makes sports glasses for runners, cyclists and mountain athletes. Best known are the photochromic Reactiv lenses and the light, frameless models you barely feel at high pace. For the mountains there are wider glasses with side shields.

For us, Julbo is above all a brand that knows what mountain light does to your eyes: photochromic lenses, a stable fit and more than 130 years of experience with eyewear.
