Products tagged with 'YY Vertical Plas Fun'

The Y&Y Vertical Plas Fun belay glasses are an inexpensive way to help belayers from having to tilt their heads back for long periods of time. This helps to relax muscles in the neck area so you're ready when it's your turn to climb. The lenses have a very high optical quality and the minimal frames mean that you can watch both your climber and your surroundings at the same time. The Plasfun also works with glasses and sunglasses so everyone can use them indoors or outdoors.
