Costa Hammerhead 580G Polarized Sunglasses
If you've got the guts you can swim with them, but we suggest you just kick back and relax while wearing them; Costa® Hammerhead 580 Polarized Sunglasses. The Hammerheads feature Costa's 580 Lightwave® glass lenses which in addition to providing 100% polarization and 100% UV protection, they also incorporate an advanced filtering compound into the lens material to reduce yellow light. This results in enhanced colors and greater visual acuity in all conditions. Lightwave glass lenses are 20% thinner and 22% lighter than typical glass lenses but they still exceed federal standards for impact resistance. Ultra-tough, full-wrap style TR-90 nylon frames with stainless steel spring hinges make Hammerhead polarized sunglasses right for any adventure.
