Black Diamond Supply Co. Outline T-Shirt

The Black Diamond Supply Co. Outline T-Shirt keeps it bold and minimal. A crisp white “DIAMOND.” text graphic sits inside a clean white box, stamped front and center. The chest screen print pops against the black base for a sharp, high-contrast look.

Built from soft cotton with a regular fit, it’s easy to wear from morning to night. Classic crew neck and short sleeves make it a year-round staple. Finished with signature Diamond detailing for that authentic edge. Simple, sharp, and built to last—this tee hits every time.
