Costa Del Mar Fly Line Sunglasses - Black - Green Mirror

The Fly Line series features high-performance optics, but always verify specific lens technology details on the product label as configurations can vary.

While durable, they are designed as lifestyle performance eyewear. Ensure you use a secure retainer strap if using them around open water to prevent loss.

Always store them in a protective, hard-shell case to prevent damage to the frame and lenses.

The frame is designed for durability and structural integrity; avoid bending the arms excessively beyond their natural resting position.

While the lenses are highly scratch-resistant, they are not scratch-proof. Avoid placing the lenses face-down on hard surfaces.

Ensure proper airflow around the frame and clean with an anti-fog spray if you frequently transition between cold and hot environments.

Use a clean microfiber cloth with a small amount of lens cleaner to gently wipe the lens in a circular motion.

Gently adjust the ear temple arms inward for a tighter grip, or consider applying non-slip silicone pads to the bridge if necessary.

Rinse the frame under low-pressure cool water and use a soft-bristled brush to clear out debris, then air dry completely.
