Costa Rincon II Sunglasses Best-selling Rincon, upgraded. Micro side shields. 580G glass. The Costa Rincon II is the evolution of Costa's best-selling Rincon frame — same iconic West Coast-inspired silhouette anglers have worn for years, with real performance upgrades layered in. Micro side shields and extended frame hooding cut peripheral light leak and protect from sun, spray, and the elements. Vented nose pads keep the lenses fog-free in humid Northeast summer or Florida flats heat. Double-injected rubber construction eliminates the delamination that wrecks cheaper sunglasses after a season. Paired with Costa's flagship 580G polarized glass lenses, this is the everyday fishing frame that earns its way onto your face for 8-10 hours a day. Key Features Micro side shields and hooded temples — reduce peripheral light intrusion Vented nose pads — airflow reduces lens fogging in humidity and heat Double-injected rubber grip points — more durable than glued rubber, no delamination 580G polarized glass lenses — Costa's best optical clarity, scratch resistant Three color options: Matte Black with Blue Mirror, Matte Black with Gold Mirror, Matte Translucent Blue with Blue Mirror Base 8 decentered lens curve for true wrap coverage Iconic Rincon silhouette — the proven West Coast-inspired frame design Specs Model Rincon II Frame Colors Matte Black, Matte Translucent Blue Lens Options Blue Mirror (580G), Gold Mirror (580G) Lens Material Polarized Glass (580G) Frame Fit Regular Lens Curve Base 8 Decentered Lens Guidance Blue Mirror: blue water and offshore work — cuts surface glare in deep water Gold Mirror: inshore and stained water — warmer contrast, better for picking out fish in green water 580G glass is heavier than 580P polycarbonate but optically clearer — the right choice when you wear sunglasses all day Always wear with a Costa retainer when offshore — glass lenses don't float Why We Like It The Rincon was already Costa's best-seller for a reason — the silhouette flatters most faces and the fit is dialed for fishing scenarios. The Rincon II upgrades fix the few real gripes anglers had: side light leak, fogging in humidity, and the rubber pads de-laminating after a couple of seasons. Add 580G glass and you've got the everyday fishing frame at a price that justifies the spend ($285). The Blue Mirror is the saltwater pick; the Gold Mirror is the better choice for inshore and back-bay anglers in green water.
