If you spend any time on or near the water, you likely know that Costa Del Mar makes some of the best fishing sunglasses out there. While the polarized glasses can be pricey (and for good reason, given their quality and glare-reducing, color-enhancing lenses), they’re currently on sale at Amazon Prime Day for up to $89 off. That means you can grab a new pair for the lowest price we’ve seen all year. Below are the best Prime Day deals on Costa sunglasses, including popular styles like the Reefton and the Rincon.
