Keep sweat at bay when you wear the Costa Slack Tide sunglasses. The temples of these athleisure frames feature vents. This means your head stays cooler and sweat doesn’t build up even on sweltering summer days. This plus Hydrolite nose and temple pads gives you a slip-proof fit. The polarized lenses help cut back on glare to reduce eye fatigue too. Choose an available lense color.

Choose between 580P polycarbonate lenses or 580G lightwave glass lenses. The 580P polycarbonate lenses are light and resist breaking upon impact. A C-WALL molecular bond on the outermost layer is scratch-resistant too. Go with the 580G lightwave glass lenses for superior clarity. Although heavier than the 580P lenses, they’re still 20% thinner and 22% lighter than traditional polarized glass lenses. Encapsulated mirrors between the glass lenses make them scratch-proof too.
