The Costa Del Mar Wader 4003 sunglasses are built for anglers who demand serious performance on the water. Named for the wading birds that patrol shallow flats, these rectangular metal frames combine Costa's legendary 580 lens technology with a secure, water-ready fit that won't quit when conditions get tough.
Costa 580 Lens Technology: See More Fish
The Wader's defining feature is Costa's patented 580 lens technology, available in both glass (580G) and polycarbonate (580P) options. These aren't ordinary polarized lenses. The 580 system filters out harsh yellow light at 580 nanometers and blocks harmful high-energy blue light, then enhances the reds, greens, and blues that matter most for sight fishing. The result is better color separation, sharper contrast, and less eye fatigue during long days on the water.
If you choose 580G glass lenses, you get Costa's sharpest optical clarity and superior scratch resistance—glass is 20% thinner and 22% lighter than typical polarized glass. The 580P polycarbonate lenses are even lighter and more impact-resistant, with Costa's C-Wall molecular bond for added scratch protection. Both deliver 100% UV protection and 100% polarization to kill reflected glare. Glass suits anglers who prioritize absolute clarity; polycarbonate is ideal if you need lighter weight and extra durability for active use.
Marine-Grade Monel Frames & Hydrolite Grip
The Wader's stainless steel Monel frames are corrosion-resistant and built to handle saltwater, sweat, and sun. Monel is a marine-grade alloy used in boat hardware and offshore applications—it stands up to the challenge. The double-bridge aviator design offers medium coverage with a large lens front sized for average to larger heads.
What sets the Wader apart is the fully integrated Hydrolite rubber that flows throughout the temples. This proprietary hypoallergenic rubber grips better when wet, so the frames stay put even in salty, sweaty conditions. Fully adjustable nose pads let you dial in a custom fit and help reduce fogging. These are sunglasses that work as hard as you do.
Prescription-Ready Performance
The Wader is prescription-ready, so you can add your Rx and get the same Costa 580 performance with your exact vision correction. Whether you're sight-casting for redfish, running offshore, or just spending the day on the boat, the Wader delivers the clarity and protection serious anglers rely on.

Frequently Asked Questions
Are Costa Wader sunglasses prescription-ready?
Yes, the Costa Wader 4003 sunglasses are prescription-ready. Most Costa sunglass frames can be produced with authentic Costa Rx lenses. Visit an authorized prescription dealer to discuss lens options and ensure the best fit for your vision needs.
What is the difference between Costa 580G and 580P lenses?
Costa 580G lenses are made of glass and offer superior optical clarity and scratch resistance, while being 20% thinner and 22% lighter than typical polarized glass. Costa 580P lenses are polycarbonate—lighter, more impact-resistant, and more affordable. Both filter harmful yellow and blue light and provide 100% UV protection and polarization. Glass is best for ultimate clarity; polycarbonate is ideal for active use and all-day comfort.
What is Monel and why is it used in Costa frames?
Monel is a marine-grade, corrosion-resistant metal alloy commonly used in boat hardware and offshore applications. Costa uses Monel in their metal frames because it's super tough and stands up to saltwater, sweat, and harsh conditions on the water. If you spend a lot of time fishing or boating, Monel frames are built to handle the challenge without corroding or degrading.
What does Hydrolite rubber do on Costa Wader sunglasses?
Hydrolite is Costa's proprietary hypoallergenic rubber used on the nose pads and temples of the Wader. It prevents slippage and actually grips better when wet or sweaty, ensuring the sunglasses stay securely in place during active use. The Wader features fully integrated Hydrolite rubber throughout the temples for a comfortable, secure fit even in salty conditions.
Do Costa Wader sunglasses provide UV protection?
Yes, all Costa Wader sunglasses provide 100% UV protection, blocking 100% of UVA, UVB, and UVC light up to 400nm. The 580 lenses also filter out harmful high-energy blue light (HEV) and are fully polarized to eliminate reflected glare from water and other surfaces, reducing eye strain and providing superior protection during long days outdoors.
What size head do Costa Wader sunglasses fit?
The Costa Wader features a large lens front designed to fit those with an average-sized head. It's a medium-coverage frame with a 6-base wrap that balances style and performance. The fully adjustable nose pads allow you to customize the fit for your face shape, and the Hydrolite rubber temples ensure a secure, comfortable fit for extended wear.

Costa Wader vs. Rincon vs. Permit: Which Fishing Sunglasses Are Right for You?
Choosing between Costa's top fishing frames comes down to frame material, coverage, and how you'll use them. Here's how the Wader stacks up against two of Costa's most popular models.
Wader vs. Rincon: Metal vs. Nylon
The Costa Rincon is the brand's #1 bestseller for good reason—it's a versatile, lightweight rectangular frame that works equally well on the water and around town. The Rincon uses bio-resin nylon construction, making it lighter and more comfortable for all-day wear. The Wader counters with marine-grade Monel metal frames that offer superior durability in harsh saltwater conditions and a more premium feel.
Both frames offer the same 580G and 580P lens options and similar rectangular shapes sized for average to larger heads. The key difference: the Wader's fully integrated Hydrolite temples provide more secure grip in wet conditions, while the Rincon's lighter nylon frame reduces pressure on your nose and ears during extended wear. If you want maximum durability and don't mind a bit more weight, choose the Wader. If all-day comfort is your priority, the Rincon is hard to beat.
Wader vs. Permit: Coverage and Wrap
The Costa Permit is an extra-large frame with an 8-base wrap that hugs your face for maximum sun and wind coverage. It's built for serious anglers who need side protection and minimal light leak. The Permit features side vents to reduce fogging—a feature customers specifically praise—and a Hydrolite polymer lining that creates a snug, secure fit even at high boat speeds.
The Wader offers medium coverage with a 6-base wrap and a more classic aviator aesthetic. It's less aggressive and more versatile for everyday wear, but provides less peripheral protection than the Permit. If you fish in extreme sun and need maximum coverage, the Permit is the better choice. If you want a frame that transitions easily from the boat to the dock to dinner, the Wader's aviator styling is more adaptable.
Wader vs. Brine: Premium Metal vs. Affordable Nylon
The Costa Brine shares the Wader's rectangular shape and medium coverage but uses lightweight nylon construction instead of Monel metal. The Brine is more affordable and lighter on your face, making it a solid choice for anglers on a budget or those who prioritize comfort over premium materials.
The Wader's Monel frames offer better long-term durability in saltwater environments and a more distinctive double-bridge aviator design. If you fish frequently in harsh conditions and want frames that will last for years, the Wader's marine-grade construction is worth the investment. If you're looking for a great rectangular frame at a lower price point, the Brine delivers Costa's 580 lens technology in a lighter, more affordable package.
The Verdict
Choose the Wader if you want premium Monel metal construction, classic aviator styling, and fully integrated Hydrolite grip for secure performance in wet, salty conditions. It's the best choice for anglers who demand durability and don't mind a bit more weight for superior build quality and distinctive looks.
