Description

A light, panoramic pair of glasses with a fixed lens for bright light. The lens is always category 3, so you know exactly what you get.

The Spectron HD 3 lens gives a clear, high-contrast picture in the sun. You notice that on open terrain, where light bounces off the ground and you would otherwise squint. Above the nose there is a ventilation opening, so the lens fogs up less when you work hard.

Not sure? Choose this one if you mainly run in daylight sun. If you keep switching between forest and open terrain, the Frequency Reactiv is more practical. You'll find more ventilation and side protection with the Fury.

Lots of sun and little hassle: 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.

Frequently asked questions

What does category 3 mean?

Category 3 is a dark lens for bright sun. It lets through about 15% of visible light and is too dark for forest or dusk.

Does the Frequency run small or large?

Julbo lists the Frequency as a smaller fit. If a regular sports frame fits you well, this model will too. If you have a wide face, look at the Faster XL.

Can I wear the glasses with a helmet?

Yes, the thin, flexible temples are made to be worn with a cycling helmet.
