Suncloud's Sentry Sunglasses bring together superior materials with top-notch glare-reduction and sun protection features. The Sentry's strong impact-resistant frames are made from optical-grade Grilamid TR-90 nylon, combining flexibility and comfort with long-lasting wear. Megol nose pads ensure that you achieve an optimal fit even in humid conditions, thanks to their hydrophilic composition. Its injection-molded lenses are polarized to protect against 100% of UVA, UVB and UVC rays. Suncloud's glare-reducing innovation specifically screens out horizontal reflective light waves to help eliminate both ambient and direct glare.
