They Slack Cover feature the same sleek lines and legendary comfort as the Slack, while adding removableside and nose shellsthat offer extra UV protection for high-altitude activities. In addition, their double-bridge design gives them a resolutely modern and assertive look, while the curved arms ensure a perfect fit, even when the effort becomes intense. The removable shells offer increased protection against UV rays and splashes.

Featuring category 4 Spectron HD lenses offering maximum sun protection, this model of glasses ensures clear, high-contrast vision in all circumstances, ideal for high-altitude activities.
