What to Look for in Costa Fishing Sunglasses

For everything you need to know about Costa Del Mar, visit our Costa Sunglasses Buyer's Guide. For a quick recap of why Costa makes the best fishing sunglasses, continue reading below.

Frame Technology

For long days out on the water, Costa fishing sunglasses are built to last while keeping you comfortable. All of the frames in today's lineup are made from eco-friendly TR90 nylon. This material is highly resistant to fluctuating temperatures and extremely lightweight to wear. It's also saltwater-safe and anti-corrosive, so you can enjoy the view with extra longevity.

Costa frames also utilize Hydrolite™ rubber to create comfortable and secure grip. Your frame will stay perfectly in place, even when the boat starts rocking. They also get tackier when wet, so no need to worry about frame slippage from unexpected splashes or on choppy days.

Lens Technology

As for lenses, 580 lens technology is the reason fishermen never leave the dock without their favorite Costas. Designed to enhance contrast and color while protecting against UV and HEV light, 580 lenses are some of the most well-loved lenses we know. Providing 99.9% glare reduction, all Costa 580 lenses are polarized to give you the most comfortable visual experience while making details pop. Available in 7 colors to enhance your specific environment, you'll get the perfect level of tint and color to compliment your fishing spot.

Best Men's Costa Fishing Sunglasses

Let's reel in the frames!

Costa Tailwalker

Kicking off our lineup, we're starting with a new frame from Costa's Core Collection. Introducing the Tailwalker, an active lifestyle frame ready for your next fishing trip. Square lenses provide excellent coverage, while built-in side shields deliver extra peripheral protection on bright, sunny days. As for the fit, you'll get a custom sizing experience thanks to the Tailwalker's two adjustable features: maneuverable Hydrolite™ nose pads and locking-lever temples that easily click to adjust the length.

Tuna Alley

The Costa Tuna Alley is no stranger to our best of fishing lineups at SportRx. It won the REXYS award of the best fishing sunglasses of 2018 and continues to be a favorite because of its impressive performance out on the water. In addition to featuring the Costa proprietary tech we know and love, like TR90 nylon and Hydrolite™ rubber, the Tuna Alley has a unique ventilation system to keep you cool. A patented 3-hole vent draws air away from the frame to keep your vision fog-free and clear at all times.
