          +02Key facts

          01
          The Short Story
          The San Francisco 49ers shirt that survives a full season of Tuesdays.
          02
          The Gist
          The San Francisco 49ers black jersey is built to the game-day build, which decides the knit weight.
          03
          The Deal
          Polyester holds dye better than cotton, which is why the San Francisco 49ers black tone stays put.

          +03FAQ — common questions

          Does the San Francisco 49ers black jersey come with a player name on the back?
          Only if the listing title says so. This page covers the black shirt exactly as described above, and a named version is a separate listing with its own measurements and price.
          How does the Rivalries Collection run sit in the range?
          It's a distinct release rather than a recoloured current shirt, so it sits alongside the main run instead of inside it. Numbering, trim and colour follow that release.
          Can two people wear the same Christian McCaffrey jersey in different sizes?
          Yes, and it's a common order. The size range is wide enough that an adult and a child can often both be fitted from this one listing. Take both together and they go out as a single parcel.
          What is this jersey made from?
          A polyester knit with mesh panels under the arms and across the back. Polyester is used because it holds dyed colour far better than cotton and doesn't go shapeless after a dozen washes.
          Is the jersey cotton or polyester?
          Polyester, and that's deliberate. It holds dyed colour far better than cotton and doesn't go shapeless after a dozen washes. On a black shirt in black the difference shows up early, since pale dye on cotton fades first.
          How heavy is the San Francisco 49ers jersey?
          Light, and noticeably lighter than a cotton t-shirt of the same size. That's what makes the San Francisco 49ers shirt packable and comfortable in warm weather.

          +04Deeper detail

          01
          Construction
          Side seams on the black jersey are flatlocked, so there's nothing to rub against a shoulder.
          02
          Care routine
          A cool iron on the reverse is fine if you must, but the black shirt rarely needs it.
          03
          Long-term value
          If it's a gift, the size you'd buy yourself is almost always right for a black shirt.
