Seattle Mariners Jerseys
Start with the colourway you like, then pick the cut — that is the fastest way through this Seattle Mariners range.
Pick between a relaxed fan cut and a tighter replica cut. The fan cut leaves room through the chest and shoulders so it layers over a tee. The replica cut follows the body more closely, so if you want the silhouette you see on first pitch, that is the one to choose — just size up if you are between two sizes. Browse by club, by colourway, or by cut - sizing runs from S to 3XL.
How these Seattle Mariners jerseys are built
The collection is arranged around cut rather than price. Loose fan cuts suit everyday wear and layering. Trim replica cuts sit closer to the body. Once you know which silhouette you want, the rest of the choice is colourway and size, and the full measurement chart lives on our size guide.
What the jersey is made of
The knit is light enough to wear through summer and structured enough that it does not cling. That balance is why the same jersey works for a stadium afternoon and for everyday wear.
Wash with similar colours for the first couple of cycles and the darker colourways will stay deep.
How to pick the right one
Ordering for a group? Keep the cut and colourway the same across every size and the jerseys will look like a set rather than a pile of similar shirts.
