Relaxed Muscle Tank #26 – Jack’s 78s Collection

Lightweight and airy, this flowy scoop muscle tank carries a worn-in, vintage race patch graphic that feels quietly nostalgic. The soft drape flatters the shoulder and upper arm while the relaxed silhouette moves with you—easy to layer under a utility jacket or wear solo on warm mornings. The muted two-tone number at center gives it a retro-sport vibe without shouting; it ages into your rotation and becomes a go-to for long runs, coffee runs, or slow weekend adventures. Sized on the smaller side, it’s best chosen with one size up for a breezier fit. Made from a soft polyester/viscose blend, the fabric is featherlight and breathable so it feels like a second skin on miles-long days.
