Riding downtown to meet your friends is far more enjoyable when the low sun isn't blinding you. The POC Know Sunglasses block out excess light to keep your ride and rooftop event fun. The Know features a Grilamid frame that is lightweight and flexible, yet durable enough to withstand daily wear. The nylon lenses have a Ripel treatment to ensure your vision remains clear and to make cleaning the lenses easy. Hydrophilic rubber pads secure the frame on your nose, minimizing movement even in the presence of precipitation or perspiration.
