Costa Del Mar Brine Polarized Sunglasses – Tortoiseshell/Green Mirror

Costa Del Mar Brine polarized sunglasses deliver premium glare-cutting performance with the brand's signature 580P lens technology—a proprietary polarization standard that exceeds standard UV400 protection. The Tortoise/Green Mirror frame combines a classic tortoiseshell acetate construction with green-tinted mirrored lenses, ideal for bright outdoor and driving conditions. Costa Del Mar holds strong reputation among serious eyewear enthusiasts and fishing/water-sports communities for optical clarity and durability. At $177.60 (20% off list), this sits in the mid-to-premium segment—justified by optics and build but positioned above mass-market alternatives like SUNGAIT or Knockaround. Frame fit runs standard; lenses are distortion-free. Comes with a protective case and cleaning cloth. Warranty support typical of the brand. Best suited for buyers prioritizing optical quality and heritage brand credibility over budget entry points.
