The \u003cstrong\u003eCosta Tailfin 580G\u003c\/strong\u003e in Matte Black with Blue Mirror glass lenses was made for the moment the tailfin breaks the surface — and everything else disappears.\u003c\/p\u003e\u003cp\u003eNamed for the pursuit, the Tailfin is Costa's answer to the angler who needs a frame that moves with them. Lightweight, wrap-style, and built around Costa's legendary 580G polarized glass, it's the kind of eyewear that stops feeling like gear and starts feeling like an extension of how you see the world.\u003c\/p\u003e\u003ch3\u003eBlue Mirror 580G Lens\u003c\/h3\u003e\u003cp\u003eThe Blue Mirror lens sits on a gray base, cutting harsh overhead light while keeping colors true and the horizon sharp. Whether you're scanning open water or running offshore, this lens was built for bright, high-sun conditions where lesser lenses wash out. With just enough tint to tame the glare and enough clarity to read the water, it's the go-to choice for bluewater and beyond.\u003c\/p\u003e\u003ch3\u003eWhy 580G Glass\u003c\/h3\u003e\u003cp\u003eCosta's 580G lenses aren't just polarized — they're engineered to filter the specific wavelengths of light that cause the most eye fatigue and glare on the water. The result is a lens that's sharper, more color-accurate, and more durable than standard polarized options. Glass doesn't scratch like plastic. It doesn't distort. It just performs.\u003c\/p\u003e\u003ch3\u003eFrame Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWrap-style fit\u003c\/strong\u003e — full peripheral coverage for open-water conditions\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable nose pads\u003c\/strong\u003e — nonslip, fully customizable for your face\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eC-Wall® lens 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 — blocks all UVA and UVB light\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMatte Black frame\u003c\/strong\u003e — low-glare finish that won't spook fish or blind your crew\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecs\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLens:\u003c\/strong\u003e Blue Mirror 580G Polarized Glass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Color:\u003c\/strong\u003e Matte Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVendor:\u003c\/strong\u003e Costa Del Mar\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU:\u003c\/strong\u003e 097963967235\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThe Tailfin is for the ones chasing tails.
