Say NO to belayer's neck!
YY Belay glasses are prism glasses that can reflect the vision vertical to the belayers.
In traditional belaying, belayers need to raise their heads to watch their climbing partners. The neck discomfort can lead to a distraction which will put the climbers in possible danger.
The chronic injury from belaying can result in a severe problem: belayer’s neck. The ingenious YY belay glass can help to belay your climbing partner without straining their necks.
By avoiding raising the head for a long time and reducing pain in the neck or upper back, the belayers can prevent cervical pain related to contractures of joints and be more attentive during the belaying.
