This clear visor hat is composed of a 3D printed plastic head band with top cover to provide extra protection from aerosols and a clear PETG plastic front shield measuring approximately 8.5" x 11" (216mm x 282mm). The head band is secured in the rear with a piece of elastic cord.
This visor is based on work done by Timothy Prestero of https://www.designthatmatters.org/. The design exists in the public domain. We are manufacturing these visors at a low margin to meet community demand.
