I don't know about you but when I find a good pair of sunglasses I guard them with my life.  They need to fit perfectly around my ears and not feel heavy over my nose.  Kenny Chesney feels the same way, the guy is in the sun a lot and fishes so sunglasses are super important to him.  Yesterday he introduced his new line of Costa Sunglasses in conjunction with his”Goin’ Coastal tour”.  nashvillecountryclub  reports that the limited edition Costas will go on sale on Thursday March 17.  They’ll also be available at venues where his tour stops.  Proceeds generated from the sale of the Kenny Chesney Limited Edition Costas will benefit ocean conservation group Coastal Conservation Association (CCA), a shared cause for both Chesney and Costa.
