PolarizationYes — Costa 580P technology

The Costa Del Mar Brine is a premium polarized sunglasses offering from one of the eyewear industry's most respected brands. These frames feature 580P polarized lenses — Costa's proprietary lens technology designed to cut glare effectively — paired with full UV400 protection and available in the striking Red Sky/Gray colorway. The Brine features a classic, medium-sized frame style with a wrap-around design suited for driving, fishing, and outdoor activities.

Build & Fit: Costa frames are known for solid hinge construction and durable materials, though some users report occasional fit variation across head shapes. The 59mm width suggests a standard-to-wide fit.

Who it's for: Serious anglers, boaters, drivers, and eyewear enthusiasts willing to invest in proven polarization technology and brand heritage. Costa commands premium pricing ($150–$200+ depending on lens coating) — justified by optical quality and durability, but not entry-level value.

Warranty: Costa typically includes a 1-year manufacturer's warranty on defects.

Value Position: Mid-to-premium tier; strong performance and trusted optics, but pricier than mass-market alternatives like SUNGAIT or Knockaround.
