This coordinated athletic set features a lightweight, moisture-wicking gray short-sleeve t-shirt with an abstract white line-print pattern and subtle iridescent logo accents near the chest. Paired with black drawstring-waist shorts featuring a distinctive vertical row of holographic/iridescent J-shaped graphics on the left thigh—suggesting a stylized brand mark or decorative motif—and matching small reflective details on the lower leg. The fabric appears to be synthetic performance material (e.g., polyester/spandex blend), offering stretch, breathability, and quick-dry properties ideal for training, gym sessions, or casual streetwear. The clean modern cut, elastic waistband with external drawcord, and minimal branding align with contemporary sport-luxe aesthetics. Suitable for warm-weather activities, the set balances functionality with visual interest through its tonal base and vibrant multicolor accents. While the specific brand is unidentifiable due to lack of clear trademarked logos (no Swoosh, Jumpman,三条纹, etc.), the design language echoes emerging street-sport brands focused on tech-fabric apparel. Ideal for daily wear, light workouts, or athleisure styling in spring/summer.
