VV Vertical SOLAR UP are new belay glasses. The optical prisms are mounted on a swivel joint. They can simply be tilted up or down, depending on whether you need to look through the periscope or have an unobstructed view. The glasses have integrated sun lenses, so they are ideal for outdoor summer climbing. The sun lenses can be removed in cloudy weather or when climbing indoors. YY Vertical offers quality optics and a comfortable frame construction.
