Costa Del Mar Fantail Pro Polarized Fishing

Costa Fantail Pro polarized fishing sunglasses with the 580P polycarbonate lens deliver Costa's proprietary 580nm filter in a lighter-weight, more impact-resistant lens format than the 580G glass option. The 580P lens cuts water glare and enhances the color channels that improve fish visibility and water reading — the same Costa filter technology in a lens that's safer for overhead casting, offshore fly fishing, and active inshore fishing where lens impact risk is higher.

580P Polycarbonate: When Lighter and More Impact-Resistant Wins

For fishing from a flats boat where fly line regularly passes near your face, offshore sport fishing where spray and impact risk are elevated, and any application where the consequence of a cracked glass lens mid-trip is significant, the 580P polycarbonate is the smarter choice over 580G glass. The optical performance difference is real but modest — the 580 filter's enhancement of contrast and color separation for sight fishing works effectively in both glass and polycarbonate. Active anglers in high-risk lens environments benefit more from polycarbonate's durability than they'd benefit from glass's optical precision.

• 580P polycarbonate lens — lightweight, impact-resistant with Costa's 580 filter
• 580nm filter — same color contrast and glare elimination as 580G
• Fantail Pro frame — co-injected rubber grip, wider temple coverage
• Lighter than 580G — less fatigue on full-day fishing sessions
• Costa lifetime warranty — repair and replacement coverage

Choosing Between 580G and 580P

580G glass: best for dedicated inshore and flats anglers who prioritize maximum optical clarity and scratch resistance in lower-impact conditions. 580P polycarbonate: best for active anglers, offshore fishing, fly fishing with line near the face, and any situation where the lens takes regular impact exposure. Both deliver the full benefit of Costa's 580 filter — the choice is about durability and weight trade-offs, not optical filter performance.
