x PAF Running T-Shirt

The ON x POST ARCHIVE FACTION (PAF) Running Shirt treats performance wear like an architectural design piece. In collaboration with the South Korean label POST ARCHIVE FACTION (PAF), ON’s technical innovation meets PAF’s progressive design language to create a running shirt that goes beyond just sports use. Made from a lightweight, quick-drying performance fabric 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 optimize airflow and give the silhouette a clean, technical look. The standout color, Gale, is a subtle gray-blue tone that feels cool, modern, and understated, highlighting the futuristic vibe of the collaboration. Reflective dot graphics add functional accents and give the minimalist design extra depth without breaking its simple aesthetic. The subtle ON x PAF co-branding finishes the look and points to the special partnership between the two brands.
