Costa Tuna Alley Pro Sunglasses

PRO Series. 580G glass. Built for offshore fishing professionals.

The Costa Tuna Alley Pro is the updated legend — a redesigned PRO Series frame on the Tuna Alley platform that's been worn by serious offshore captains since the original came out. The PRO Series upgrades are real: updated vent system to manage sweat, six dedicated fish-spotting features, improved Hydrolite® rubber that doesn't slip when you're wet, adjustable nose pads, top hooding and side shields to block peripheral glare, and metal keeper slots that won't break out. Paired with 580G polarized glass lenses — the best optical performance Costa makes — this is the frame to wear when you're on a marlin charter or running a tuna boat.

Key Features

Lens Guidance

• Blue Mirror: the offshore lens — cuts blue-water glare and enhances contrast on the surface
• 580G glass is heavier than polycarbonate but optically clearer; the right choice when you wear glasses 8+ hours a day on a boat
• Always wear with a Costa retainer offshore — glass lenses don't float

Why We Like It

The PRO Series is a real upgrade over the original Tuna Alley. The vent system actually works for sweat management on a hot August offshore day, the top hooding cuts the light bleed that drives serious anglers nuts, and the adjustable nose pads mean you can dial in a frame that doesn't slip when you're leaned over a rod. 580G glass remains the gold standard for full-day wear — if you're spending the money on Costa, this is the lens to get.
