One size definitely does not fit all, especially in over-the-glass (OTG) goggles. The Smith Showcase OTG goggles are designed specifically for smaller adult faces looking for eyeglass compatibility. Their semi-rimless frame provides a wide field of view, while our ChromaPop lens tech brings enhanced contrast and color definition to every light condition. The whole idea behind wearing goggles is for the best vision possible. You might as well get the fit to match.
