Category 4 lenses are engineered for those who like to push the limits.
The beloved Alpine Collection holds a special place in our hearts, but we thought it was time to level up. While the Helio lens is a go to for everyday adventure, we wanted to provide something for those who like to play without boundaries.
Thus our darkest lenses yet. Category 4 lenses allow only half the amount of light to filter through as standard Sunski lenses. Endorsed by the National Ski Patrol, they are engineered for optimal performance in the brightest extreme alpine conditions. Bring your adventures to new elevations.
