Kevin Durant to Endorse Sparkling Ice

NBA superstar Kevin Durant has signed an endorsement with carbonated water drink, clinic Sparkling Ice.

“I’ve always challenged myself on the basketball court, but this offseason is really the first year I’m challenging myself off of it — on the business side,” the Oklahoma City Thunder forward told ESPN.com.

“This is a brand I drink every day that I love and I wanted to be a part of it. I want to help them get to the next level.”

Sparkling Ice has silently blown up over the past couple years, going from $25 million in sales in 2010 to expected revenue of $500 million in 2014.

Michael Yormark, president and chief strategy officer of Roc Nation Sports, said that Sparkling Ice came up in an initial meeting with Durant and his agent Rich Kleiman.

“He told us that this brand was already a part of him and he wanted to have an official relationship,” Yormark said.
