Julbo Slack Cover Spectron S4

The basic model Slack is already a versatile all-rounder with a confident style, suitable for a variety of conditions. The Slack Cover retains the lightweight design and high wearing comfort while adding removable side shields and a nose guard, transforming the vintage glasses into a true mountain eyewear. Equipped with a double bridge in a distinctive style, these glasses are offered with three different lens options, including SPECTRON HD Polarized, a polarized lens that enhances the perception of contrasts, colors, and details while reducing eye strain. With the Slack Cover, you are fully protected, so even the icy mountain winds won't affect you.
