Asked and answered

Everything buyers ask about this Boston Celtics jersey

Quick answer

A black Boston Celtics baseball jersey for Men's / Youth, in quick-dry performance knit with a cool-touch finish. It runs true to size, sits straight through the body, and stays comfortable in a packed stand. Machine wash cold and air dry to protect the lettering. Part of the NBA range.

Q01Is the sizing on a Boston Celtics jersey the same as a regular t-shirt?▾
Close, but not identical. Measure your chest rather than trusting your usual letter size, because a Boston Celtics jersey is cut with room through the shoulders and armholes for movement. If you're between two sizes, size up. Men's / Youth sizing on this one runs true to the chart.
Q02Will a Boston Celtics jersey work layered over something else?▾
It will. There's room through the armholes and shoulders of this Boston Celtics cut, so it goes over a tee or a hoodie without bunching across the back or pulling at the seam. The body is straight-cut rather than tapered, which is what keeps the shape clean when there's another layer underneath.
Q03How should I wash a Boston Celtics jersey so the black lasts?▾
Cold water, inside out, and air dry. That's the whole routine for the Boston Celtics jersey, and it takes less effort than most people expect. Heat is what dulls a colour and moves the fibres, so the drying stage matters more than the wash cycle itself. Skip fabric softener too, because it coats the knit and flattens the finish.

Boston Celtics fans know the feeling — the build-up, the roar, the last-minute nerves. This black baseball jersey is made for exactly those ten minutes.

If you want a name and number on the Boston Celtics shirt, add it before checkout and we'll confirm the spelling with you first. Getting a surname wrong is the one thing that turns a great gift into a problem, so we always double-check before it goes to the press.

Answers before you order

More questions buyers ask

▾
Is the Boston Celtics jersey true to size?▾
It is. Order your normal size for a regular fit, or one up if you want the looser terrace look. The size chart on this page converts a chest measurement directly into a size, which is the number that matters here. If you're between two, take the larger one and you'll wear it more often.
Is it safe in the dryer?▾
We'd recommend air drying instead. Heat is the main cause of print cracking, and it also moves the fibres, so a jersey can come out a size smaller than it went in. A clothes line costs you nothing and protects both the finish and the fit at the same time.
Can I buy a Boston Celtics jersey as a gift if I don't know their size?▾
Yes — and if you're not sure, go up rather than down. Too big gets worn, too small gets returned. Send us the wearer's usual size or their chest measurement and we'll pick for you, and we'll hold the exchange open so they can swap it themselves.
Is it breathable?▾
Yes. Ventilated panels sit where heat builds up, which is why it stays wearable long after the whistle. The knit is mid-weight rather than heavy, so it moves air without going transparent in sunlight, and the same weight holds up in a cold stand as well as a warm one.
What if the name I want is already on the shirt?▾
Tell us what you're after and we'll confirm the spelling and the layout before anything is applied. If you want a different name to the one shown, that's a custom order and we'll set it up for you. Lettering is the one thing we can't undo once it's pressed on.
Is the black Boston Celtics 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 Boston Celtics shirt in another colour, order the size you take in that one and you'll be right.
Will the colours fade?▾
Team colours are applied to hold their depth rather than sit on the surface, so they stay sharp season after season. Washing cold and inside out is the whole trick — warm water and a hot drying cycle are what flatten a colour over time. Air dry it and you won't see a difference after a year.
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.

Worn more often than whatever Boston Celtics shirt it replaces. That's the whole point.
