YY Vertical Plasfun EVO belay glasses use prisms to let you watch your climbing partner without constantly tilting your head back. Useful during longer belays at the gym or crag.

The prisms redirect the view of the climber into your field of vision, helping you keep your head in a more natural position. This is useful on long routes and when your partner is working a difficult move.

Before your first session, get used to the view through the prisms and find a comfortable fit. The glasses complement your belay kit while you continue to monitor your partner, the rope and your surroundings.

Key features

• Prisms for watching the climber
