Ultra-lightweight and durable, the Suncloud Sentry Sunglasses incorporate the brand's signature lens and frame technologies. The Sentry's injection-molded polycarbonate medium-fit frames feature an 8 base curve that stylishly wraps around your face. Crafted from optical-grade TR-90 Grilamid nylon, the Sentry's frames offer ultimate impact resistance and flexibility. Hydrophilic megol nose pads provide exceptional comfort and fit. Its polarized lenses shield against 100% of UV A/B/C rays while reducing both direct and ambient glare. Suncloud's glare-reduction technology selectively filters out horizontal reflecting light waves that interfere with visibility.
