          The one-paragraph version

          What you're looking at is a royal Seattle Seahawks jersey cut for younger fans. The pattern is drafted once and used across the whole run instead of being scaled up, which is why the shoulders and hem stay in proportion.

          +02Key facts

          01
          In Short
          A royal Seattle Seahawks shirt built for people who actually wear their shirts.
          02
          Why It Works
          The royal jersey runs the same royal tone across every size in the list.
          03
          The Basics
          The royal Seattle Seahawks shoulders are cut slightly wide, which is why it sits flat when you stand.

          +03FAQ — common questions

          Where does the Cooper Kupp name sit on the royal Seattle Seahawks jersey?
          Across the upper back with the number below it, on the royal body. Both are stitched rather than transferred, so they sit flat against the knit instead of standing proud.
          Is the Cooper Kupp jersey heavier than the blank version?
          Only where the lettering sits on the Seattle Seahawks shirt, and not enough to notice on a hanger. The Seattle Seahawks knit, the cut and the royal body are identical to the blank shirt, so the difference is a few grams across the upper back.
          Will a royal jersey still look right in two seasons?
          That depends mostly on how you wash it. Cold, inside out, air dried, and a royal shirt holds shape and colour for years.
          Is the Seattle Seahawks royal crest printed or stitched?
          Stitched and appliqued on this one. That removes the peeling problem printed badges have, which is the single most common complaint on lower-cost royal shirts.
          Does the jersey have a ribbed collar?
          It does, and it's one of the details that decides how a royal shirt ages. A ribbed collar keeps its edge instead of stretching out, which is the first failure point on a thin knit.
          How does this Seattle Seahawks jersey compare with a budget one?
          Mostly in the knit and the stitching. Lower-cost royal jerseys tend to use thinner fabric and a printed crest, which is exactly where fading and peeling complaints come from.
