Protection against our favorite element, water. Our lenses are designed with a shield to help prevent any optical distortion stemming from water buildup.


Keeps your lens clean. Our lenses include an oil-resistant coating to help avoid smudging or fingerprint marks from distorting your field of view.


In the shop or on your commute to the beach, our anti-static protection helps prevent any dirt, dust or small particles from sticking to your lens.


Helps prevent scratches. A scratch-resistant coating that helps ensure our lenses stand up to your active lifestyles.

The Untangled Collection helps prevent discarded fishing nets from entering our oceans by recycling them into Costa sunglasses—and now—optical frames. Our partners at Bureo® work together with fishing communities to recycle used fishing nets into high-quality, NetPlus™ products. An ocean free of discarded nets is a sight worth seeing.

Key features:
- Made from NetPlus™ recycled fishing nets and stainless steel
- Timeless, lightweight designs
- Durable and comfortable
