Fashion house CALVIN KLEIN unveiled its latest Calvins or Nothing campaign starring actor Michael B. Jordan lensed by photography duo Mert Alas and Marcus Piggott. The actor stars in a new photoshoot for Calvin Klein’s Athletic and Modern Cotton Performance Collection, which features soft and stretchy briefs, boxers and tanks designed for comfortable movement and maximum breathability. Made from a quick-dry material, the pieces are as perfect for hitting the ropes as they are for hitting the sack, with a range of styles and sizes.
