Integrated micro side shields and hooding help block peripheral light, while the vented Hydrolite nose pad keeps the frames secure and helps prevent fogging. Meanwhile, sweat-management channels and eyewire drains keep sweat from reaching your eyes.
Mainsail and Aleta also feature Costa’s polarized, color-enhancing 580 lens technology for exceptional clarity. The scratch-resistant lens cuts haze and blur while enhancing key colors for improved clarity and definition. Built with eco-friendly Bio-Resin, the Mainsail and Aleta frames are lightweight and durable.
