The Untangled Collection helps prevent discarded fishing nets from entering our oceans by recycling them into Costa sunglasses. 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.
