Hard-core adventures require gear designed to deliver. In any conditions. At every latitude. Every one of these frames were crafted with the explorer in mind, giving you the vision to cut your own trail through the world. Go big, and do it wearing these.

Life isn't always about facing down a billfish or climbing an unclimbed mountain face. Sometimes it's about a hammock, a sweating cerveza and crashing waves. This collection lets your eyes live the life of leisure, with full-on Costa performance and tech.

The performance of Costas. The utility of bi-focals. They're C-Mates, and like every pair of Costas, they deliver 100% Polarization and UV protection and our Lifetime Warranty. In 1.75x or 2.50x magnification, they'll help you see every adventure closer than ever. (Sorry, but C-Mates can't be shipped to Minnesota, Rhode Island and New York.)
