Home, Away or Alternate — Which Seattle Mariners Jersey?

Seattle Mariners plays in the MLB alongside St Louis Cardinals, San Francisco Giants, Tampa Bay Rays, San Diego Padres and Texas Rangers. We stock the current home and away jerseys for every club in the competition, so you can follow a full season from this page.

The Seattle Mariners home and away jerseys exist because two teams cannot take the field in the same colour. The alternate is a third option teams break out for primetime, rivalry and throwback games.

Jersey	Role	Colourway
Home	Primary, worn at home	Team's primary colour
Away	Road games	Contrast, usually lighter
Alternate	Select marquee games	Often the boldest of the three

Throwbacks are a separate category again — a revival of a past design rather than a current-season option. Where the team has released one, it is listed in this collection.

Choosing the Right Fit

Sizing is where most Seattle Mariners orders go wrong, so it is worth thirty seconds of attention before you buy.

Size	Chest (inches)	Fits like
S	36–38	Slim adult
M	38–40	Standard adult
L	41–43	Relaxed adult
XL	44–46	Loose adult
2XL	47–49	Oversized / layering

Youth and toddler sizes are listed by age rather than letter — a youth large fits roughly a 12–13 year old. Women's cuts use their own size run and are slimmer through the waist than the men's equivalent.

Care & Wash Guide

Three rules keep a Seattle Mariners jersey looking new: cold water, inside out, no tumble dryer.

Cold wash, 30 °C. Heat is what lifts printed crests.
Inside out. Protects the print from rubbing against other garments.
Air dry. A tumble dryer will crack a nameset faster than anything else.

Skip fabric softener — it leaves a residue that blocks the fabric's moisture-wicking finish. If the shirt picks up a mark, spot-clean it rather than running a full cycle.

How to Wear a Seattle Mariners Jersey

Jersey styling has moved well past the terraces. A Seattle Mariners shirt works over a long-sleeve tee in cooler months and on its own in summer, and the current fabrics are light enough to wear all day.

If you are layering, size up. The cut is designed to sit close to the body, which leaves no room underneath.

Seattle Mariners Jersey FAQ

Do Seattle Mariners jerseys run true to size?

SportsFanFit's Seattle Mariners jerseys use the standard fan-version cut, which is relaxed through the chest and shoulders. Order your usual letter size for a match-day fit, or size up one if you prefer a looser streetwear look. Youth and toddler sizes are sized by age — see the chart on each product page.

Can I add a player name and number to a Seattle Mariners jersey?

Yes. Pick the player from the dropdown, or type your own name. Printed namesets ship within 1–2 business days and use the team's home-plate font. Stitched lettering is available as an upgrade on selected designs.

Are Seattle Mariners jerseys machine dryable?

No. Polyester does not absorb water the way cotton does, so a Seattle Mariners jersey dries quickly on a hanger. Skip the tumble dryer — the heat is what damages the crest and the printed nameset.
