The functional heart of Belay Specs are the prisms that "bend" the light through reflection and refraction by 60 degrees. This means your neck has to bend that much less when you're watching your climbing partner through the Belay Specs. The image quality of the prisms is fantastic, providing a crisp, clear view of the climber and surrounding cliff. Many first time users comment: "I swear I see better looking through these!"
The frame is the skeleton of Belay Specs and positions the prisms in front of the users eyes. The frames are stamped in Utah from tough but springy stainless steel sheet. The material allows the arms and nose pieces to be adjusted by the user for a custom fit for different nose and heads shapes and sizes. The springy arms gently grip your head and prevent the specs from falling off.
The arms and nose piece are covered with silicone which provides some padding for comfort and some grip to keep the Belay Specs in place. A keeper cord keeps the glasses close at hand for quick transition while belaying. Belay Specs come wrapped in a microfiber cleaning cloth inside a tough plastic case to handle the abuses that can happen while in a pack and at the crag.
