After wearing these belay glasses for one day, we felt like idiots we didn't get a pair sooner! Seriously, anyone who climbs (and subsequently belays) should have a pair! They work for ALL climbs (not just steep ones), saving the neck, and providing a safer belay because your belayer can actually keep watching you from nearly any angle. In fact, the ability to view your climber from almost any direction and have good peripheral vision means even if you catch yourself eying another climber on your project, you can still keep your eye on your climber at the same time!
