Sometimes it's just better to abide by the K. I. S. S model (keep it simple, stupid), and the Smith Cascade Classic Goggles are evidence of such. The Cascade features a durable frame and medium fit for maximum versatility, while the cylindrical dual lens provides ample airflow and prevents the buildup of moisture and fog. Additionally, the hypoallergenic face foam not only provides a comfortable fit, but it's also moisture-wicking to prevent that hyped-up sauna feeling all over your face.
