x PAF Running T-Shirt

The ON x POST ARCHIVE FACTION (PAF) running shirt treats performance wear as an architectural design object. In collaboration with the South Korean label POST ARCHIVE FACTION (PAF), ON’s technical innovation merges with PAF’s progressive design language to create a running shirt that goes far beyond just sports use. Made from a lightweight, quick-drying performance material with a high recycled polyester content, the shirt offers a comfortably dry feel and maximum freedom of movement. Side mesh panels, an integrated ventilation slit on the back, and a taped back section ensure optimized airflow and give the silhouette a clear, technical look. The subtle black tone feels clean, modern, and understated, emphasizing the futuristic character of the collaboration. Reflective dot graphics add functional accents and give the minimalist design extra depth without breaking its reduced aesthetic. The discreet ON x PAF co-branding completes the look and highlights the special partnership between the two brands.
