THE COSTA SLACK TIDE STORY
When the tide goes slack, so does the fishing. In Costa’s athleisure Slack Tide sunglasses you can move on to another spot to chase a different adventure. This laidback west coast inspired frame is infused with functional elements - Hydrolite® padding, pin hinge, ventilation and 580 Polarized, 100% UV Protection lenses so you can see through multiple tide changes.
Polarized sunglasses block glare from light reflecting off flat surfaces, making them very popular among people who spend a lot of time outdoors, driving or particularly near water. Light-sensitive people and those who have had cataract surgery can also benefit from wearing polarized sunglasses.
