The name on the back is the whole decision. This Seattle Mariners alternate jersey is the Cal Raleigh answer for young fans.
Shoulders are set for movement rather than for the mannequin. Mesh panels run the side seams to move air.
Fan-version build with the Seattle Mariners colourway and Cal Raleigh lettering applied front and back — the detail that separates it from a plain team tee. Every order is checked before dispatch and travels with end-to-end tracking. The colourway is matched to the on-field look rather than to a screen approximation. Sizing follows the US scale, so the letter size you normally wear is the right call.
It reads as Seattle Mariners gear anywhere, but the palette points straight back to Seattle, Washington and T-Mobile Park.
How to Wear It
Works as button-down streetwear styling away from the ballpark, too.
Fit & Sizing
US youth sizing (youth S–XL). The cut is relaxed rather than slim, so there is room to move and room to grow. The usual letter size is the right starting point.

Frequently asked questions
What if the jersey does not fit when it arrives?
You are covered by our 30-day hassle-free guarantee with zero restocking fees. If the fit is not ideal, contact our support team and your first size exchange is completely free.
What is the difference between this fan version and an on-field jersey?
This is fan apparel built for supporters: a lightweight mesh body and a relaxed cut, not the athletic cut worn by players on the field.
Is the fabric light enough for summer doubleheaders?
Yes. The breathable mesh keeps air moving during long afternoons in the bleachers, so it stays comfortable from the first pitch through extra innings.
How long does delivery take and can I track the order?
Orders dispatch within 1–3 business days and arrive in 7–15 business days with full end-to-end tracking. Orders of $57 or more ship free.
