Last year Kenny Chesney partnered with Costa Sunglasses for a line of sunglasses. Now, he's expanding that line with five new styles.

The new styles available are Hammerhead, Caballito, Switchfoot, Hammock and Maya, and will retail from $129 to $199. Each kit comes with a Kenny Chesney cleaning cloth, hat and neoprene case.

"The partnership with Costa Sunglasses and the Coastal Conservation Association is a natural extension of who I am and what I believe in," said Chesney. "We live the coastal lifestyle - it's part of who we are. It's up to us to help protect and preserve the oceans and beaches for future generations."

A portion of proceeds from the sunglasses go to the Coastal Conservation Association. The partnership is successful! Already raising $50,000 for the CCA.
