Costa Del Mar re-wrote the book on lens clarity when they produced the 580G glass lens. And now, after two years of testing and tweaking, they've done it again, offering that same unmatched optical precision and polarization, but this time at a fraction of the weight with their new Costa 580P polycarbonate lens. Take that unbelievable clarity out on the open water with the Peninsula Polarized Sunglasses, and see what you've been missing.

  • Universally proportioned frame and an 8-base curvature hugs your nose and temples without overwhelming your entire face
  • Costa's 580P polarization completely kills strain-inducing yellow light (like glare), while enhancing the naturally-occurring reds, greens, and blues that enhance your vision's contrast acuity on the water
  • All 580P lenses are fused with Costa's proprietary C-Wall coating that resists scratches while repelling water, oil, dust, and anything else you can throw at them

Great sunglasses

  • Familiarity:I've used it several times
  • Fit:True to size

I just got these Costa Peninsula's in Black/Coral and they look great. Sadly I have to return them due to their weight. Just too heavy to wear all day which I what I need. Anyone just wearing them on a casual basis would probably be happy with them.

Our they mens or women's?
