      Youth San Francisco 49ers Game Day Custom Jersey

      New season, familiar colours. This San Francisco 49ers jersey is cut for comfort first and finished so it still reads clearly from the back of the stand. Short version: San Francisco 49ers jersey in the game day cut, for young supporters, 2026.

      What you get

      • Sewn-on badge detail
      • 100% Polyester knit with a flat, matte finish

      The Game Day build

      The Game Day build is the matchday-facing tier of the range: a performance-weight knit, a close athletic cut, and badge and trim work finished to match what is worn for kick-off.

      Sizing across the family

      Adult, women's and youth cuts are graded separately, so the same design fits a grown supporter and a younger one properly rather than proportionally.

      Fit and sizing

      Cut to a standard athletic shape that follows the body without gripping it.

      Fan version vs on-field version

      • Fan version: softer knit, roomier fit, lower price.
      • On-field version: closer cut, firmer fabric, premium price.
      • Team colours and crest are the same on both.

      Version, sizing and what you are buying

      What you are buying is the game day cut, which is what most supporters actually want. Same look as the on-field shirt, softer hand-feel, roomier fit, and easier to live in week to week.

      Sizes here follow a standard athletic grade for young fans. Compare the chest measurement on the size guide rather than your usual high-street letter.

      Personalisation is available on this design. Add a player's name and number or your own, and it is applied as a flat heat-sealed finish rather than a bulky patch.

      WHAT REALLY MAKES OUR THREADS UNBEATABLE?​​

      We don’t chase thread counts. Not because they don’t matter—but because true quality goes far beyond threads per square inch. Here’s what we prioritize instead:
      • ​Finest Organic Materials: We start with the purest, ethically sourced organic cotton, silk, or linen—fibers chosen for their strength, softness, and ability to age gracefully. No shortcuts, no compromises.
      • ​Meticulous Weaving: Every thread is woven with care, using time-honored techniques that preserve the integrity of the fabric. No rough edges, no fraying—just smooth, durable construction.
      • ​Gentle Finishing: Harsh chemicals? Never. We use plant-based dyes, natural softeners, and low-impact processes to finish our threads, ensuring they stay breathable, hypoallergenic, and kind to your skin.
