Product DNA What's It Do? “Project Rock is not a brand, it’s a movement. It’s a core belief, that I 100% don’t care what colour you are, how old you are, where you come from or what you do for a living. Gently used Dwayne "the Rock" Johnson collab with Under Armour t-shirt in a men's size XXL. No flaws, gently used, great condition! Whitish gray color!
