If you're attracted to style and performance like a shark to blood in the water, then you'll love the Costa Whitetip 580P Polarized Sunglasses. Named after a curious shark that patrols tropical waters, these shades are ideal for everything from island-hopping on your sailboat to fly fishing saltwater flats. Polarized lenses cut glare to help you scan for bonefish, and Hydrolite pads and temple gripper holes secure your sunglasses when you're tacking and jibing. Sporty styling provides excellent coverage from the searing tropical sun, and a vented front keeps the refreshing sea breeze flowing through.
