Don’t be fooled by imitators, there is only one original way to comfortably Belay. The CU belay glasses are an innovative new way to use prisms. While wearing these glasses, the belayer can see straight up while looking straight ahead. The high quality glass is not only very durable and clear but it actually magnifies as well. Rather than hinges, a flexible steel frame is used. The design allows them to be worn over prescription glasses or sunglasses. Completing the package is a neck attachment cord and a foam-padded plastic case.
