This coordinated two-piece tracksuit set features a sleek black zip-up jacket and matching tapered pants, 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 (appears to be a stylized butterfly or abstract emblem—unidentifiable as a known luxury brand). The pants feature an elastic waistband with drawstring, side zip pockets, and the same olive green stripe running down each outer seam. Fabric appears to be smooth synthetic blend—likely polyester/spandex—for lightweight comfort, stretch, and wrinkle resistance. Ideal for casual daily wear, light athletic activity, lounging, or travel. The minimalist design with subtle branding aligns with contemporary streetwear trends while maintaining versatility across seasons. Notable details include clean stitching, functional hardware, and a relaxed-but-tailored fit. Though tags are present, no legible brand name is visible in the image; the logo does not match any major designer or sportswear brand in the reference database. 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 generic branded item.
