Details Y&Y Plasfun Belay Glasses Belaying for extended periods can be really bad for your neck, so get a pair of Y&Y Plasfun Belay Glasses before your mate settles in for a long redpoint siege. Compact BK7 prisms let you see upwards without having to bend your neck, while still allowing good peripheral vision to negotiate the uneven crag base and manage the rope. Anyone who belays from below on the regular should consider a pair. We think they should be standard issue for climbing centre staff and SPA instructors too.
