This athletic two-piece set features a vibrant blue technical short-sleeve t-shirt paired with sleek black performance shorts, designed for optimal comfort and mobility during running or training. The t-shirt showcases a textured, breathable fabric with strategic mesh panels under the arms and along the sides for enhanced ventilation, while the crew neck offers a clean, non-restrictive fit. A subtle reflective 'ON' logo appears on the left chest in light gray, echoing the brand’s minimalist aesthetic. The matching black shorts feature an elasticated waistband with internal drawcord, side pockets with zip closures, and a small reflective 'ON' logo on the lower left leg—ensuring visibility and functionality. Both pieces are crafted from moisture-wicking, quick-dry synthetic blends to keep the wearer cool and dry. Ideal for runners, gym sessions, or active daily wear in warm weather, this coordinated set combines Swiss-engineered performance with modern sportswear styling. The L size (45–55 kg) suggests a tailored fit for medium-to-large adult builds.
