Refreshed and revitalized, the YY Plasfun EVO Belay glasses have arrived! This revolutionary eyewear boasts light and resilient plastic frames, plus enlarged BK7 prisms for a wider, more comfortable viewing experience. Perfect for climbers and glasses-wearers alike!

Profoundly adjustable for every face shape, YY Plasfun EVO belay glasses are devoted to safety and comfort—ideal for long rock-climbing operations like sport and top roping. Enjoy extraordinary quality without compromising a thing!

They allow the belayer to see directly up - operating like a periscope - without having to strain their neck back constantly. These glasses help prevent neck ache - "Belayer's Neck" - and thus improve concentration and encourage better belaying.
