The Costa Del Mar Gannet 9041 Sunglasses bring together performance and style in a women's frame inspired by one of nature's most determined travelers. Named after the gannet seabird that flies over 1,800 miles from New Zealand to Australia, these sunglasses are built for women who refuse to compromise on clarity or comfort.
Costa 580 Lens Technology: See More, See Better
At the heart of the Gannet is Costa's patented 580 lens technology, available in both polycarbonate (580P) and glass (580G) options. These aren't ordinary polarized lenses. Costa's 580 technology blocks harsh yellow light at 580 nanometers on the visible light spectrum while filtering 100% of UV rays and harmful high-energy visible (HEV) blue light. The result? Enhanced reds, greens, and blues that deliver sharper contrast, reduced haze, and superior definition—whether you're on the water, driving, or simply enjoying a sunny day.
The 580P polycarbonate lenses are lightweight and impact-resistant with a scratch-resistant barrier, making them ideal for active wear. The 580G glass lenses offer the ultimate optical clarity and are 20% thinner and 22% lighter than average polarized glass. Both options feature Costa's C-Wall coating, which provides extra scratch resistance and repels water, oil, and sweat for easy cleaning.
Designed for Real Comfort
The Gannet's pillow-shaped acetate frame offers a flattering, rounded profile that suits a variety of face shapes. The medium fit is designed for average-sized heads with a large lens front (58mm) that provides excellent coverage without feeling bulky. Hydrolite nose pads ensure the frames stay put during activity, while the distinctive water drop-shaped epoxy fill at the temple tips adds both visual interest and functional grip.
This frame is prescription-ready, so you can add your Rx and enjoy Costa's world-class optics with vision correction. The full-rim acetate construction is durable yet lightweight, and the variety of frame colors—from classic tortoise fade to vibrant marine fade and bold wahoo patterns—means there's a Gannet to match your personal style.
What Customers Say
"They fit perfectly and are very comfortable. They also do an excellent job reducing glare and the view through the lens is sharp and clear." — eBay verified buyer

If you're looking for women's polarized sunglasses that combine technical excellence with everyday wearability, the Costa Del Mar Gannet 9041 is ready for the journey.

Frequently Asked Questions
Are the Costa Del Mar Gannet 9041 sunglasses prescription-ready?
Yes, the Gannet 9041 is prescription-ready and can accommodate custom prescription lenses. The frame can accept prescriptions (SPH & CYL combined) from +3.00 to -5.00, with cylinder values up to -3.00. You can order prescription lenses in either 580P polycarbonate or 580G glass to maintain Costa's superior optical clarity and polarization.
What is the difference between Costa 580P and 580G lenses?
Costa 580P lenses are made of lightweight, impact-resistant polycarbonate with a scratch-resistant coating, making them more durable for active use and everyday wear. Costa 580G lenses are made of glass and offer superior optical clarity—they're 20% thinner and 22% lighter than average polarized glass and are virtually scratch-proof. Both lens types provide the same 580 color-enhancement technology, 100% UV protection, and 99.9% polarization efficiency.
What face shape and size do the Costa Gannet sunglasses fit best?
The Gannet features a medium fit with a large lens front (58mm width, 17mm bridge) designed for average-sized heads. The pillow-shaped frame with its rounded profile flatters oval, heart, and square face shapes. The frame includes a high bridge fit, making it ideal for those with a higher nose bridge and lower cheekbones. The acetate construction and Hydrolite nose pads ensure a comfortable, secure fit.
What is Costa's 580 lens technology and how does it work?
Costa 580 lens technology uses a patented multi-layer design that blocks harsh yellow light at 580 nanometers on the visible light spectrum. This filtering enhances the natural colors you see—boosting reds, greens, and blues—while reducing haze and blur for sharper contrast and definition. The lenses also block 100% of UVA/UVB/UVC rays and filter harmful high-energy visible (HEV) blue light, providing superior eye protection and visual clarity on the water and outdoors.
Do Costa Gannet sunglasses come with UV protection and polarization?
Yes, all Costa Gannet sunglasses feature 100% polarized lenses that eliminate reflective glare and absorb 100% of UV light (UVA, UVB, and UVC). Costa only manufactures polarized sunglasses, and the 580 lens technology provides 99.9% polarization efficiency—among the best glare reduction available. The lenses also include Costa's C-Wall coating for scratch resistance and to repel water, oil, and sweat.
What are the key features of the Costa Gannet frame design?
The Gannet features a full-rim acetate frame in a distinctive pillow shape with a medium fit and regular coverage. Key design elements include Hydrolite nose pads for a secure, comfortable grip, water drop-shaped epoxy fill at the temple tips for added style and stability, and a single bridge design. The frame is available in multiple color options including tortoise fade, marine fade, black hibiscus, and wahoo patterns, all paired with Costa's 580 polarized lenses in various tints.

Costa Del Mar Gannet vs. Inlet vs. Sarasota: Which Women's Frame Is Right for You?
All three frames deliver Costa's legendary 580 lens technology and 100% polarization, but they're designed for different priorities.
Choose the Gannet if you want:
- A versatile pillow shape that works equally well on the water and around town
- Medium coverage with a flattering, fashion-forward aesthetic
- Hydrolite nose pads and water drop temple tips for secure, comfortable all-day wear
- A frame that balances performance features with everyday style
Choose the Inlet if you want:
- Maximum sun protection with a full 8-base wraparound design
- A performance-first frame built specifically for fishing and water sports
- Spring hinges for active use and enhanced durability

Choose the Sarasota if you want:
- A smaller, more delicate cat-eye design with vintage appeal
- A frame that prioritizes fashion over maximum coverage
- Refined styling for casual beach days, cafes, and urban settings
- A petite fit for smaller faces
The Gannet strikes the best balance—it's stylish enough for daily wear but built with the same water-ready features (Hydrolite pads, C-Wall coating, full polarization) that make Costa a favorite among serious anglers. If you want one pair that does it all, the Gannet is your frame.
