Technology never sleeps. So we stay two steps ahead, pushing the limits and rethinking what's possible. This attitude guides how we design our frames and choose the materials we use to make them. Here are some of the details:

HydroliteTM:
A rubberized composite compound found in all of our co-injected temples for superior fit and grip.

GrilamidTM TR-90 Nylon:
Remarkably tough and unbelievably resistant to UV damage and breakdown. Translation? It's almost indestructible.

Stainless Steel:
In our frames, it means stain and corrosion resistance. (Good if you're on the water.) In our hinges, it means easy adjustability for maximum comfort. In general, it means business.

Monel:
Super-tough, corrosion-resistant and made for marine environments, this nickel silver alloy is truly hard-core.


Built by Hand. Costa sunglasses are hand-built by an actual person at our headquarters in Florida. Each product is inspected and re-inspected before they leave the building. We don't want them in your hands if they're anything short of perfect.

Backed for life. If you venture to some of the wild, unpredictable places we do, chances are your gear takes a beating. The sun. The salt. The spray. All of these can kill the average pair of sunglasses. Not ours. And if something does happen to your Costas, we'll fix them. If it's our fault, we'll fix them for free (all you pay is $9.95 for processing). No fine print. No questions asked. And no expiration date. We call it our LIFETIME WARRANTY, and every pair of our sunglasses gets one.
