Who says men aren't into fashion?!

Check out the University of North Carolina basketball team go BERSERK over their new Jumpman jerseys -- the first time in school history the Tarheels hoops squad will rock a black uni.

Marcus Paige surprised his teammates by rockin' the first sample into the team locker room -- one guy literally falls on the floor ... and #3 Kennedy Meeks is so shocked, his jaw nearly his the floor.

Check out the video, tipped our way by our friends at BSO.
