YY Vertical

Originally founded in the French mountain-base city of Grenoble, YY Vertical makes climbing eyewear designed for comfort and efficiency.

Their signature belay glasses feature a vertical mirror lens that makes it easier for a belayer to support a climber without straining their neck. This leads to better safety and more comfort for the wearer by keeping the neck in its natural position throughout the activity.

The YY design provides a double vision for both the climbing proceeding (vertical vision) and surroundings (peripheral vision).
