Costa Ulu 580G Sunglasses Tortoise/Gray Gradient 580G, One Size

The Ulu 580G Sunglasses start with a handmade Bio Acetate frame, built with a core-wire temple and a filigree detail inspired by the surf break the frame is named after. That craftsmanship doesn't come at the cost of performance. The Rose Gradient 580G glass lens still absorbs harmful blue light and filters out harsh yellow tones, so the same clarity that makes Costa's technical lineup work is built into a frame designed for everyday wear. What Our Gearhead(R) Experts Are Saying:"I wore these to a friend's backyard party right off a morning at the beach, and the lens still cut the glare walking back to the car. I didn't have to choose between looking good and actually seeing well."
