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.
The Costa sunglasses ‘fit’ guide is a range from Narrow, Regular to Wide with most people choosing Regular. Fit is a combination of both the size of the sunglasses and the features of the frame, together. The features of our sunglasses influence the way the sunglasses fit, like the hinges and temple construction. Use the ‘fit’ guide to select a Costa sunglass frame that will be comfortable and perform for you.
