          +02Key facts

          01
          The Short Story
          Lightweight, breathable navy Seattle Seahawks knit, and honest about how it fits.
          02
          The Gist
          If flatlocked seams matter to you, the navy Seattle Seahawks Game tier is the one that has them.
          03
          The Deal
          Weight-wise the navy Seattle Seahawks shirt sits between a cotton tee and a performance shell.

          +03FAQ — common questions

          Does the Seattle Seahawks romper jersey smell after a long wear?
          Not more than any polyester knit. The Seattle Seahawks mesh panels help air move, which slows the build-up, but a synthetic fabric holds odour longer than cotton if it isn't washed.
          Can I wear a romper jersey to work?
          On a casual day, yes. In a navy shirt the only loud element is the crest, so it reads as sportswear rather than costume. Pair it with plain trousers and skip matching socks.
          Do the Jaxon Smith-Njigba numbers match the squad list?
          The numbers shown are the ones associated with Jaxon Smith-Njigba in Seattle Seahawks colours, taken from the squad list for that period. Where a player changed navy numbers, the most recognisable one is used.
          Do you do matching newborn and adult Jaxon Smith-Njigba Seattle Seahawks sets?
          Often, yes. The same Seattle Seahawks colourway usually exists across more than one audience run, so you can put a set together by ordering from each listing.
          Is the newborn navy Jaxon Smith-Njigba Seattle Seahawks romper jersey the same pattern as the adult one?
          No, and that's the point. The newborn navy pattern is drafted separately, so shoulders, body length and sleeve width all move together. Scaling an adult pattern down is how newborn gear ends up boxy.
          Is this newborn romper jersey cut differently from the standard version?
          Yes. The newborn Jaxon Smith-Njigba Seattle Seahawks pattern is drafted separately rather than scaled down from an adult navy shirt, which is why the proportions hold together. Shoulders, body length and sleeve width all move as a set.

          +04Deeper detail

          01
          Sizing guide
          The navy crest sits flat instead of puckering, because the stitch density is right.
          02
          Construction
          The navy collar is ribbed and holds its edge, which is the first thing to go on a thin knit.
          03
          Care routine
          Thirty degrees, short cycle, no dryer.
