He’s also the founder of the Just Keep Livin Foundation (a reference to his legendary role in “Dazed and Confused”), a nonprofit that encourages health and wellness among high school students. At this year’s ACL Fest, a portion of proceeds from certain pieces of festival merchandise will benefit the foundation, many of them including lines from McConaughey’s famed Wooderson character. There’s, of course, an “Alright alright alright” shirt, and one emblazoned with “L-I-V-I-N”.

McConaughey’s wife, Camila Alves, showed off the merch at the festival on Saturday:

We got an early sneak peek preview of the merch tent before the festival started last weekend:
