I own 3 pairs of costas...2 Of the 3 are the women's cocos. Both pairs have had frame damage twice in the past year causing the lens to fall out and either get lost in the water or shatter on the ground.  I sent both pairs back last August and paid for new lens on each pair 7 months later same exact thing happened to one pair and a month later to the other pair.  The cocos are poorly made in my opinion because I also have a pair of the pawleys and have had them over a year now with no problems.  Highly recommend finding a different style if your considering buying cocos.
