YY Vertical Clip Up is a flip-up belay prism attachment for your own glasses. It lets you watch your climbing partner without constantly tilting your head back.

Keep wearing your everyday glasses while the prisms redirect your view towards the climber. The flip-up design lets you move the attachment out of the way when it is not needed.

Use it during longer belay sessions at the gym or crag. Check the fit on your glasses before use and take some time to get used to the view through the prisms.
