Made from a highly engineered plastic called poly para xylene (PPX). This injected frame is specifically designed to be durable and lightweight. It'll float in the ocean, pool, lake, river, or any other water you may find yourself in. The embossed rubber logo is 100% waterproof and won't chip after drops, won't fade in the sun, and won't wash away in the ocean's salt water. The polarized lenses offer 100% UV400 protection and are hydrophobic (repels water) and oleophobic (repels oils). The 5 barrel stainless steel hinge creates maximum strength and durability and the premium microfiber pouch removes fingerprints, smudges, and dirt while guarding them from scratches, dust, and everyday hazards. Comes with a 1 Year Limited Warranty. These shades are unsinkable, it's like a life jacket for your face!
