The Smith Reason OTG goggles are over-the-glasses compatible. In other words, you can wear them over your prescription glasses to maintain the sharpest vision possible. Designed with larger face shapes in mind, they provide a helmet-compatible, pressure-free fit that lets your glasses sit naturally for comfort that lasts all day. The ventilated design regulates airflow for a fog-free view even when wearing a helmet. Product Code: EAOPJ3BL0221 Smith Optics Reason OTG Goggle - Slate + Ignitor Mirror Lens | Goggles UK
