As an angler, protecting the habitat where you recreate is important to you. Costa aims to reduce plastic waste by constructing the frames of the Pescador Polarized 580G Sunglasses out of recycled fishing nets. The entire frame, including the PLUSfoam nose and temple pads, is recyclable so you can retire them without guilt when it's their time. During their life, the polarized Lightwave Glass lenses cut through the glare that bounces off of the water so you can see the fish. Costa even included a ReFleece case to protect your shades when you're not wearing them so they're ready to go when you are.
