This coordinated activewear set features a high-neck, full-zip long-sleeve jacket with ergonomic seam lines, two vertical zippered side pockets, and thumbhole cuffs for enhanced mobility and coverage. Paired with high-waisted nine-part (9/10 length) leggings offering a sleek, streamlined silhouette that ends just above the ankle—ideal for yoga, Pilates, light training, or athleisure styling. The fabric appears to be a smooth, stretch-responsive performance knit with matte finish, providing compression, moisture-wicking, and 4-way stretch for comfort during movement. The 'Mystery Green' hue is a muted, sophisticated forest-green tone—elegant yet sporty—perfect for transitioning from studio to street. Designed with clean lines and minimal hardware, the set emphasizes functionality without sacrificing modern aesthetic. Ideal for daily wear, casual outings, or low-to-moderate intensity workouts in spring or fall. No visible branding or logos confirm it as a generic or private-label design, likely produced for e-commerce resale under a local label (e.g., '琪露服装' watermark suggests a Chinese retailer).
