The Costa Del Mar Hybrid Aleta Sunglasses seamlessly blend elegant, fashion-forward female styling with highly functional ocean technology. Named after the Spanish word for "fin," this specialized model features a lightweight Matte Translucent Sitka frame crafted from durable bio-resins. Outfitted with high-clarity Gray 580G polarized Lightwave glass lenses, this configuration guarantees exceptional, true-to-life color neutrality and sharpness across intense overhead sun. The adventure-ready framework integrates low-profile micro shields and hooding to block out distracting peripheral light leak, paired with vented Hydrolite nose pads to prevent lens fogging. Double-injected Hydrolite rubber lining along the temples increases its structural grip when wet, ensuring comfortable, secure placement whether you are out exploring deep waters or enjoying casual beachside living.
