Smith Reason OTG GoggleSmith Reason OTG Goggles We never take clear vision for granted so you can. The Smith Reason OTG goggles are over the glasses and ODS compatible, meaning you can wear them over prescription glasses or use our ODS prescription lens insert to keep your view sharp. Built for larger faces, they offer a helmet compatible, pressure free fit that lets your glasses sit naturally. A ventilated design regulates airflow for a fog free view even with a helmet.
