Alright, alright, alright — looks like someone has traveled back to the '80s! Matthew McConaughey recently donned a fanny pack (and defended wearing it!) while attending the Red Sox-Astros game at Fenway Park in Boston on Sunday, Aug. 17.

The Oscar winner, 44, laughed off his style choice with a big grin during an interview with CSN Houston's Julia Morales. He attended the game with his 6-year-old son Levi, and topped off his retro bag with a white T-shirt, khaki pants, a baseball cap and sunglasses.

"I'm not afraid of the fanny pack. You gotta kinda put it on the side to make it look a little not as nerdy, but still, practicality wins out," the Dallas Buyers Club actor said. "I got so much gear in here that I don't want in my pockets."

"You know what, how many times have you been around someone and they're like, 'Aw, man, I forgot so and so and I gotta go back to my car.'" Pretending to take something out of his hip pouch, he added: "I got mine right here."

"Keep doing it, keep wearing it," he told Morales, who admitted she, too, wears a fanny pack from time to time. "They'll come back, some decade from now."
