"The Julbo SLACK is bold, brazen, and versatile enough to adapt to every occasion. Lightweight and super comfortable to wear, with a double-bridge frame design that’s both audacious in style and ruggedly reliable. Available to buy in three different lens options, including high-definition Spectron HD, a polarized lens that amplifies detail, enhances contrast and color, and reduces ocular fatigue for all-day comfort. Also available with Spectron 3 and Spectron 3 Polarized. Designed to fit wider faces."
