See Other Languages: Virgin Serilium

Virgin Serilium was the original material used for the plastic frame glasses. Originating in the Frogskins and Blades, Oakley used it into the M Frame era. While they employed the term less in the 1990s they continued to apply it to later M Frames and Sub Zero / Zero's. From 1994 to 1999, O Matter was supposedly replacing Serilium, however the brittleness of the early Jackets may possibly be due to Oakley still using a formula similar to Serilium.
