Wind and water are a formula for liquid shrapnel. That's why the glare reduction and high contrast of our vented lenses are protected against droplet buildup with a specially formulated hydrophobic coating. A restraint system anchors the frames when you hit the swells, and rogue waves only increase the adhesive properties of their UnobtainiumŪ nosebombs and earsocks. All Oakley eyewear is warranted for one year from the date of purchase against manufacturer defects.
