These are premium navy blue jogger-style sweatpants from Stone Island Shadow Project, featuring the iconic black rectangular patch with a central circular grommet and gold-tone horizontal lines on the left thigh—a signature detail of the Shadow Project sub-line. Made from high-performance technical fabric (likely lightweight stretch nylon or polyester blend), they offer a modern, tapered fit with elasticated cuffs and waistband for comfort and mobility. The minimalist design emphasizes functional aesthetics, with clean seams, subtle side pockets, and a refined silhouette suitable for streetwear-forward styling. Ideal for urban casual wear, layering in transitional seasons, or as a statement piece in contemporary menswear ensembles. The fabric appears smooth with slight sheen, suggesting wind-resistant and quick-dry properties typical of Stone Island’s technical approach. Tag still attached confirms authenticity and new condition.
