Costa Del Mar Brine — tortoise acetate wrap sunglasses with 580P copper polarized lenses, worn with case.
The Brine is one of Costa's most recognized fishing-oriented wrap frames, built around their 580 lens platform which blocks high-energy visible light at 580nm for enhanced contrast on the water. The 580P designation means polycarbonate construction — lighter than glass, with the same proprietary Costa tint technology. The tortoise/copper combination is a proven pairing for low-to-mid light offshore and inshore conditions. Decorative ventilation ports on the lower frame face and silver Costa logo medallions on the temples are hallmarks of the original Brine design.
