For those who bleed saltwater, Costa's Brine sunglasses are one of the most useful fishing tools in any tackle box. Hydrolite temples, co-injected, co-molding technology and our storied 580 lens technology, these Costa men's sunglasses deliver comfort and durability to anglers whose greatest love is bending a rod. Because to some, performance isn't just nice it's necessary. A small lens front for those who prefer to cover a smaller portion of the face. Offers a more secure and comfortable fit for those with a high nose bridge and lower cheekbones. A good choice if the bridge of your nose is above the level of your pupils.
