When Relwen Founder Jamie Rupp got his hands on a batch of vintage athletic tees from the midcentury—super-soft, durable, and still up for daily workouts after more than half a century—he knew he had to make his own. So he turned to the fabric that made those originals so special: ringspun jersey cotton. The tightly twisted fibers create a smooth, exceptionally durable fabric perfect for daily wear. Cotton herringbone neck taping and straddle-stitched armholes ensure the collar and shoulders retain their structure, while the pocket adds extra utility we always appreciate.
