Why San Diego State Aztecs supporters pick this baseball jersey

Q01Does this San Diego State Aztecs jersey come in Youth sizing?▾
It does — this San Diego State Aztecs listing is Youth sizing in the black colourway. The selector on this page shows exactly what's in stock, and the chart converts a chest measurement straight into a size. If the size you want isn't showing, message us and we'll check what we can source.
Q02Is a San Diego State Aztecs jersey see-through in sunlight?▾
No. The knit is solid enough through the body that the San Diego State Aztecs jersey doesn't go transparent in direct sun, which is the usual trade-off on a light summer jersey. Mesh sits where airflow matters — under the arms and across the back — rather than through the front panel, where it would show.

Answers before you order

San Diego State Aztecs jersey questions, answered

▾
Will a San Diego State Aztecs jersey fit over a hoodie or a jacket?▾
Yes — this one has room through the chest and shoulders, so it goes over a hoodie without pulling across the front. If layering is the plan, take your normal size for a close wear or one size up for a relaxed look. The hem is long enough that it still looks deliberate rather than short.
Can I iron it?▾
Yes, but on a low setting and never directly over printed or stitched detail. Turn it inside out and use a pressing cloth between the iron and the fabric. Most creases fall out on the line anyway, so with this knit it's usually not needed at all.
Is the fabric stretchy?▾
It has give through the shoulders and armholes so you can move freely, without being a stretch fabric through the body. That's deliberate: stretch through the middle is what makes a jersey bag out at the hem over time. This one keeps its shape instead.
How do I know it will look like the photos?▾
Every listing shows the actual colourway and construction you receive, and each batch is checked before it ships. If anything looks different when it arrives, contact us and we'll sort it. Screen calibration is the usual culprit, so tell us what you're seeing on your display.
Can I get it in a larger size?▾
Extended sizing is listed in the selector on this page, so check there first for what's available in this colourway. If your size isn't showing, message us with what you need and we'll check what we can source, rather than have you settle for a fit that isn't right.
Is the black San Diego State Aztecs shirt cut differently from the other colourways?▾
The measurements are the same across the colourways, so a size that fits you in one fits you in the other. What changes is the colour, not the pattern. If you already own a San Diego State Aztecs shirt in another colour, order the size you take in that one and you'll be right.

Wear the San Diego State Aztecs jersey once and you'll know which drawer it lives in.
