Uniplexi Convex has a very interesting shape and new design. The Convex is made in chrome colour and in junior (M) and senior (L) sizes. The visor in this product is made from highly durable injection-moulded polycarbonate, using an optically perfect mould, which guarantees perfect optical clarity, which is constant on all pressed pieces. In the event that the Plexi is not damaged by scratches the visor is practically unbreakable. If the Plexi is scratched it can be replaced with a new visor. Replacing the visor is very simple. An anti-fog layer is applied to the interior surface of the visor and an anti-scratch layer is applied to the exterior surface of the visor. These are hard varnishes of a thickness of 5 microns (0.005 mm), which remain on the visor throughout its useful life.
