Created as the world’s first sport performance polarized shield-style sunglasses, the Zeal Optics Airestream gives you exactly what its name implies: a shield from the stream of air (and wind, debris and UV rays). Ultra-lightweight while retaining its strength and resilience, the Airestream is ideal for protection while lounging or while dashing down the sand. Adjustable nose plates offer a custom fit to eliminate eyelash rub and co-injected silicon ear temple pads offer a comfortable, secure fit. Import.
