I don't know specific fabric names but it's a stretchy material that is nearly see-through (kind of like nylons), we doubled up the front of the mask to prevent skin from showing but left the back with only one layer to assist with cooling the wearer. Around the eyes and nose there is a plastic mask glued in place to prevent the nose from being squished and this also provided a place to glue the lenses so they wouldn't harm the wearer. There is hockey tape and sewing thread around the fabric eye holes which in turn were glued to the lenses....
... other than that I have no idea, lol!
oh wow. such attention to detail, its amazing - i just can even tell you XD
