Y&Y Clip Up Belay Glasses
The Clip Up is an evolution for all spectacle wearers.
Just clip it on your own glasses and belay your partner with comfort.
It fits on most glasses and sun glasses and with a small movement it can be switched between the positions Off and On.
The trapezoid-shaped prisms allow a wider vision on the climber while keeping an important peripheral vision.
Clip and belay!
