This coordinated two-piece tracksuit set features a sleek black zip-up jacket and matching tapered sweatpants, both accented with contrasting olive green side stripes for a sporty yet refined aesthetic. The jacket has a stand-up collar, full-length front zipper, zippered side pockets, and a small embroidered logo on the left chest—appearing as a stylized abstract emblem (possibly a butterfly or wing motif), though no definitive brand mark is identifiable. The pants feature an elasticated waistband with drawstring, side zip pockets, and the same olive green stripe running down each outer seam. Constructed from smooth, lightweight synthetic fabric with a slight sheen, the set offers comfort and ease of movement, suitable for lounging, light workouts, or casual streetwear styling. The minimalist design and neutral color palette make it versatile across seasons. While tags are present, they display generic branding (e.g., a white tag with a butterfly-like symbol and a black tag with indistinct script), insufficient to confirm a known designer or sportswear brand. Notably, the watermark '中山市润鑫正电子商务' indicates a Chinese e-commerce seller, suggesting this may be a private-label or unbranded garment. Ideal for daily wear in spring, fall, or mild winter conditions.
