Relaxed Muscle Tank #12 – Jack’s 78s Collection

A lightweight, flowy muscle tank built for warm days and movement. The relaxed silhouette and soft, thin fabric drape gently, while the wide arm openings give freedom and airflow. The front shows a vintage-styled circular emblem with a bold, two-tone “12” that reads like a worn race patch—subtle, nostalgic, and quietly confident. Wear it for morning runs, studio flows, or layered under an open shirt for weekend errands. It feels lived-in from the first wear and holds its shape thanks to side seams and a ribbed collar. Sized to run small; consider sizing up for a roomier fit.
