{"product_id":"costa-tailfin-black-green-mirror","title":"Costa Tailfin 580G Sunglasses - Matte Black Green","description":"\u003cp\u003eGreat eyewear shouldn't require a great fit compromise. The \u003cstrong\u003eCosta Tailfin 580G\u003c\/strong\u003e in Matte Black with Green Mirror glass lenses is the same performance-driven waterman frame — now sized for those who've always had to make do with frames that were just a little too wide, a little too heavy, a little too much.\u003c\/p\u003e\u003cp\u003eThe small sizing on the Tailfin isn't a scaled-down afterthought. It's a purpose-built fit for a face that deserves the same full Costa experience as everyone else on the water.\u003c\/p\u003e\u003ch3\u003eBio-Resin Frame: Lighter Than It Looks\u003c\/h3\u003e\u003cp\u003eThe Tailfin's Bio-Resin construction sets it apart from standard nylon frames. It's chiseled, refined, and engineered to be lightweight without feeling fragile. The Matte Black finish keeps glare off the frame itself — no reflections bouncing back into your field of vision when the sun is high and the water is flat. Adjustable nose pads let you dial in the fit precisely, and sweat channels keep things comfortable through long days in the heat.\u003c\/p\u003e\u003ch3\u003eGreen Mirror 580G Lens\u003c\/h3\u003e\u003cp\u003eThe Green Mirror on a copper base is the inshore angler's weapon of choice. Built for sight fishing in full sun, it cuts surface glare while amplifying contrast — so you can read the water, track movement below the surface, and spot fish before they know you're there. At 10% light transmission and a Base 8 Decentered curve, it wraps aggressively for maximum peripheral coverage while keeping your forward vision sharp and color-true. Costa's 580G polarized glass handles the rest: filtering the wavelengths that cause eye fatigue and holding up to the abuse of life on the flats.\u003c\/p\u003e\u003ch3\u003eFrame Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBio-Resin construction\u003c\/strong\u003e — lightweight, chiseled, built for all-day wear\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall fit\u003c\/strong\u003e — purpose-built sizing for a precise, comfortable fit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMatte Black finish\u003c\/strong\u003e — no-glare frame that won't distract your vision\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable nose pads\u003c\/strong\u003e — fully customizable, nonslip fit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eC-Wall® coating\u003c\/strong\u003e — repels water, oil, and sweat; scratch-resistant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e100% UV protection\u003c\/strong\u003e — full UVA and UVB blocking\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase 8 Decentered lens curve\u003c\/strong\u003e — aggressive wrap for maximum coverage\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecs\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Fit:\u003c\/strong\u003e Regular | Size S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLens:\u003c\/strong\u003e Green Mirror 580G Polarized Glass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLens Curve:\u003c\/strong\u003e Base 8 Decentered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem No:\u003c\/strong\u003e 6S9113 911307 57-17\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU:\u003c\/strong\u003e 097963967259\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eSame water.
