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 floral 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 slight sheen, likely polyester or poly-spandex blend, offering comfort, breathability, and stretch for daily wear or light activity. The minimalist design balances retro athletic inspiration with modern streetwear appeal, suitable for casual outings, travel, or loungewear. Tags are still attached, indicating new-with-tags condition. While the garment resembles premium sportswear styling (e.g., similar to Moncler Genius or Fendi x Skims collaborations in cut), no verifiable brand logo matches any major luxury or sportswear house in the database. The watermark '中山市润鑫正电子商务' suggests a Chinese e-commerce reseller, not the manufacturer.
