The Julbo Fury is a 25 g sport sunglass with a wide cylindrical lens, open venting, and a REACTIV photochromic lens that covers categories 1 to 3. It fits under a helmet and is offered here in Black/Black and Mint/Grey.

What it's for

Cycling, mountain biking, running, and Nordic skiing in changing light. The lens lightens in trees and shade and darkens in open sun, so you do not need to swap lenses mid ride.

How it works

REACTIV photochromic lens: The tint adapts to the light level on its own. Julbo lists the current Fury lens, REACTIV 1-3 High Contrast, at 72% VLT at its lightest and 13% VLT at its darkest. VLT is the share of visible light that passes through the lens.

High Contrast: A tint treatment that brings out detail in the terrain.

Full Venting: An open, vented construction lets air flow behind the lens to prevent fogging.

Air Link temples: A shock absorbing elastomer insert at the end of each temple improves comfort and hold.

Grip Nose and Grip Tech: Soft, grippy inserts at the nose and temples keep the frame in place.
