Relaxed Muscle Tank #01 – Jack’s 78s Collection

This lightweight flowy tank carries a vintage-race feel with a worn, circular badge and bold ’01’ print at the chest. The relaxed silhouette and scooped muscle cut let air move freely, making it an easy layer for warm-weather runs, studio flow, or weekend coffee runs. The fabric drapes softly against skin, giving a lived-in comfort that looks intentionally relaxed and slightly sporty. Wear it with high-waisted shorts, your favorite leggings, or under an open flannel for an off-duty, retro-athletic look.
