The program will launch April 16 with a national sweepstakes for a chance to win a fly-away trip for two to Summerfest® and to Six Flags Great America in Gurnee, IL. The winners will receive travel and accommodations, tickets to the theme park and admission for two days at Summerfest, including tickets for two headlining shows in the Marcus Amphitheater.

“We are thrilled to partner with Gildan and Summerfest for this unique promotion,” said Stephanie Borges, vice president of strategic marketing and partnerships for Six Flags. “Music and entertainment are an integral part of the Six Flags experience, and this is the perfect opportunity to offer guests an exciting promotion with a high quality family brand.”

“We are excited to have the Gildan brand partner with Six Flags Entertainment,” said Rob Packard, vice president of marketing for Gildan USA. “Working with Six Flags, a family-oriented company, will help us spread our “Every Thread Counts,” quality apparel for the whole family message to the public. As the presenting sponsor of the 2016 Blake Shelton Concert Tour, partnering with Summerfest was a natural extension for Gildan to pursue.”
