High-performance activewear set from On Running, featuring a moisture-wicking, breathable olive green technical t-shirt with engineered ribbed texture for enhanced ventilation and mobility, paired with lightweight black running shorts with elastic waistband and reflective side detailing. The minimalist aesthetic is elevated by the signature 'ON' logo in subtle silver-gray on chest and thigh—designed for runners who value function without sacrificing style. Fabric blends include recycled polyester and elastane for stretch, quick-dry properties, and odor resistance. Ideal for daily training, gym sessions, or post-workout lounging. The L size (45–55 kg) offers a relaxed yet streamlined fit suitable for medium builds. Seamless construction reduces chafing, while flatlock stitching ensures durability during high-intensity movement. Perfect for summer runs or indoor cardio, this set combines Swiss engineering precision with modern athleisure appeal—elevating performance wear beyond the track into everyday urban life.
