This coordinated two-piece tracksuit set features a black zip-front jacket and matching tapered sweatpants, both accented with contrasting olive green side stripes for a sporty, modern aesthetic. The jacket has a stand-up collar, full-length front zipper, zippered side pockets, and a small embroidered logo on the left chest (a stylized butterfly or insect motif). The pants feature an elasticated waistband with drawstring, side zip pockets, and the same olive green stripe running down each leg seam. Fabric appears to be smooth synthetic blend—likely polyester or nylon—with slight sheen, suggesting lightweight breathability and wrinkle resistance. Ideal for casual daily wear, light athletic activities, or loungewear; the sleek silhouette bridges streetwear and sportswear. Tags are still attached, indicating new condition. While the brand logo is present (small embroidered emblem), it does not match any major luxury or sportswear brands in the reference database, and no clear brand name is visible on tags or labels. The watermark '中山市润鑫正电子商务' suggests a Chinese e-commerce seller, not the manufacturer. Design evokes 2000s–2010s sport-luxe trends with minimalist detailing.
