Three ways to wear the same white.

Seattle Mariners baseball jersey in white. Soft performance knit, ventilated where heat builds up, and cut true to size with room through the shoulders. Sized for Men's / Youth and built to hold its shape across a season. Cold wash inside out, air dry. Part of the MLB collection.

Colourway: WhiteFit: Men'sLeague: MLBTeam: Seattle Mariners

Quick answer

A white Seattle Mariners baseball jersey for Men's / Youth supporters, in lightweight knit with mesh through the back for airflow. It runs true to size with a relaxed drape, so size up one if you want the looser terrace look. Reinforced shoulder seams and a twin-needle hem take the wear. Part of the MLB range.

Seattle Mariners supporters don't need a ticket to wear the colours properly. This white baseball jersey works from the back row, the pub, or your own living room.

If you're between this and a heavier build, the Seattle Mariners jersey is the one you'll wear more often. Light enough for a warm afternoon and structured enough that it doesn't read as a plain t-shirt with a badge on it. Warmer weight has its place, just not in July.

Before you chooseWhat you're actually getting with this Seattle Mariners jersey▾

order by chest measurement rather than the size you take in a t-shirt. The Seattle Mariners jersey is cut differently through the shoulders.

Double-knit panels through the Seattle Mariners body for structure, single knit across the back for airflow. Comfortable straight off the hanger — no breaking-in period on the Seattle Mariners jersey, no shrink after the first wash.

Q01Does the Seattle Mariners jersey keep its shape after a few washes?▾

It does, provided you keep the Seattle Mariners jersey out of the tumble dryer. The knit is mid-weight with a stable gauge, so it doesn't stretch out at the hem the way a looser knit can. Wash cold, dry it flat or on a line, and it comes back to the same shape every time.

Q02How do Seattle Mariners jerseys fit compared with the t-shirt size I normally buy?▾

They run a touch roomier. A Seattle Mariners jersey is cut with more space through the shoulders and body than a t-shirt, so the same letter size can feel different. Go by chest measurement on the chart rather than the label in your usual tops, and size up if you're on the boundary.

Answers before you order

Common questions

▾

What is the Seattle Mariners jersey made from?▾

A lightweight performance knit with breathable mesh panelling, finished with twin-needle hems and reinforced shoulder seams. It's soft against the skin, structured enough to hold its shape across a season, and colour-matched thread runs through every seam rather than reading as an afterthought.

What sizes is the Seattle Mariners jersey available in?▾

It's offered in Men's / Youth sizing, and the selector on this page shows exactly what's in stock right now. If the size you need isn't showing, message us and we'll check what we can source rather than have you settle for a fit that isn't right.

How do I keep the Seattle Mariners colours sharp?▾

Cold wash, inside out, hang dry. That's the whole routine, and it takes less effort than most people expect. Do that and the Seattle Mariners colour stays deep instead of dulling out after a dozen washes. Avoid fabric softener as well, because it coats the fibres and flattens the finish.

What sizing should I choose?▾

Start from your chest measurement, because that's the most reliable guide on a baseball jersey — the shoulders and armholes are cut with room for movement. The size chart on this page converts that number directly into S, M, L and so on. If you land between two sizes, take the larger one.

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

You can, on most styles — add the details at checkout and we'll confirm the spelling before it goes to production. It's worth double-checking the name at that point, since applied lettering can't be changed or removed once it's on the shirt.

Which sizes does this come in?▾

This baseball jersey is offered in Men's / Youth. The size selector above shows exactly what's currently in stock, and the chart on this page converts a chest measurement straight into a size. If you land between two sizes, take the larger one and you'll wear it more often.
