Costa Blackfin Pro Sunglasses (580G Glass)

Wide fit. PRO Series tech. 580G glass. Costa's most-loved frame, upgraded.

The Costa Blackfin Pro is the wide-fit flagship Pro frame — built off the original Blackfin's beloved look and lens, with six new angler-approved additions to keep you on the water longer. Vented and fully adjustable nose pad for custom fit, sweat channels and eyewire drains to keep your vision clear, side shields, hooding, new stickier Hydrolite® rubber, and metal keeper slots that don't break out under hard use. Paired with Costa's 580G polarized glass lenses — the gold standard for clarity, scratch resistance, and optical performance during long days on the water.

Why We Like It

The Blackfin has been one of Costa's best-selling frames for years because the wider fit covers more eye area — less peripheral light leak, more comfortable for anglers with wider faces. The PRO Series upgrades fix the original Blackfin's only real shortcomings (light bleed, sweat management, rubber pad delamination) without changing what made the frame popular. 580G glass at this price ($249-$269) is genuinely Costa's premium optical performance, and the build quality justifies the spend for anyone who fishes seriously.
