Named for the Break, Built for Wherever You Go
The Ulu takes its name from one of surfing's most celebrated reef breaks, and the frame earns that legacy. Costa drew the bold filigree temple detail directly from the wave's character, then wrapped it around a sophisticated soft-square lens shape that reads at home on the water or across a city block. Every frame is handmade from Bio Acetate, giving it a depth and translucency that injection-molded plastics simply cannot match.
580G Polarized Glass Lenses
Costa's 580G technology is polarized glass at its most refined. The "580" designates the proprietary spectral profile: the lens absorbs harmful high-energy blue light (HEV), enhances reds, greens, and blues to sharpen contrast and color fidelity, and filters the harsh yellow wavelengths that cause eye fatigue. Glass outperforms polycarbonate in scratch resistance and optical clarity, and the polarization layer eliminates glare off water, sand, and pavement. Base 6 curvature gives the lens a moderate wrap that covers peripheral vision without distorting a wide field of view.
Frame Construction and Fit
The Ulu is cut to a wide fit, so it proportions well on broader face shapes and sits comfortably without pinching at the temples. The core-wire temple provides structural rigidity that keeps the frame from flexing out of alignment over time, while the Bio Acetate exterior stays lightweight against the skin. The filigree engraving along the temple arms is a signature design element that sets the Ulu apart from Costa's more minimal silhouettes.
Where It Works
Costa built the Ulu to travel. The description from Costa themselves: "perfect for exploring far-off cultures, or cruising to your local BBQ." That range is by design. The wide, soft-square lens provides broad UV coverage whether you're on the water or running errands. Find it in store and online at Island Water Sports in South Florida.

Frequently Asked Questions
- Are Costa Del Mar Ulu sunglasses polarized?
- Yes. Every Ulu ships with Costa's 580G polarized glass lens, which eliminates glare off reflective surfaces like water and pavement while enhancing color contrast.
- What is Costa 580G lens technology?
- 580G is Costa's polarized glass lens system. The spectral filter absorbs high-energy blue light (HEV), enhances reds, greens, and blues for sharper contrast, and cuts harsh yellow wavelengths that cause eye fatigue. The glass construction adds scratch resistance and optical clarity beyond polycarbonate alternatives.
- What does Bio Acetate mean and why does it matter?
- Bio Acetate is a plant-derived acetate that is more sustainable than petroleum-based plastics. It is also more dense and visually richer than injection-molded nylon, giving the Ulu its depth and translucency. Each Ulu frame is handmade, so the Bio Acetate is worked and polished by hand rather than stamped from a mold.
- What face shape does the Ulu fit?
- The Ulu is designed around a wide fit, making it proportionate for broader or wider face shapes. The soft-square lens shape works across oval, round, and heart-shaped faces by adding balanced structure.
- How do I clean and care for Costa polarized glass lenses?
- Use a microfiber cloth and lens-safe cleaning solution. Avoid paper products, clothing fabric, and harsh solvents, which can scratch the glass or degrade lens coatings. Store the Ulu in its case when not in use to protect the Bio Acetate frame and lens surface.
- Is the Costa Del Mar Ulu a women's frame?
- Yes. The Ulu is designed and proportioned as a women's silhouette, with a wide fit and a sophisticated soft-square lens shape that suits a range of face structures.

- The Ulu is available in store and online at Island Water Sports in South Florida. Call 954-427-4929 for product questions or in-store assistance.
