If you have already bought three Boston Celtics jerseys and none of them get worn, the problem was never the Boston Celtics colours. It was the cut. This Fast Break in green is cut properly, and it changes how often you reach for it.

From parcel to match day
01
Pick the colour and the cut
a knit that keeps the green of the Boston Celtics Fast Break jersey even after several washes, because the colour is set into the yarn.
02
How the Fast Break is put together
A Boston Celtics Fast Break jersey with a taped shoulder seam and a ribbed collar, which is what keeps the green version looking sharp on an adult. Everything on this Boston Celtics Fast Break jersey in green that you can see from the concourse is applied flat, which is why the finish looks even.
03
Sizing and how it hangs
The Boston Celtics Fast Break jersey in green fits an adult true to size, and the body length is what makes it work both tucked and untucked.
04
Where it earns its keep
The Boston Celtics Fast Break jersey in green is not only for match days. It is for an adult who wears their Boston Celtics colours when nobody is watching either. A Boston Celtics jersey like this also solves the problem of standing in a queue for an hour in a cold Boston Celtics stadium concourse.
We list the measurements we actually use on the Boston Celtics jersey, so the green Fast Break size you pick is the size that arrives.

Feel and finishPolyester knit, true to size+
The knit used on this green Boston Celtics Fast Break jersey is the same weight across the Fast Break range, so you can order different Boston Celtics colours in one size. The mesh in the body of a Boston Celtics jersey is what does the work on a hot night, so it is the part worth paying attention to.

Care and orderingWashing, returns and support+
Wash the Boston Celtics Fast Break jersey cold and dry it flat. Heat from a tumble dryer is the fastest way to shorten the body of a green jersey. If you wash it hot, the fibres of the Boston Celtics Fast Break jersey in green move and the green flattens out faster than any amount of wear would do it.
Your Boston Celtics Fast Break jersey in green arrives with a tracking link by email, and if the Fast Break is not right we will arrange the return from there.
Questions before you order
Is the price of the Boston Celtics jersey fixed?
The price shown is the current price. The green Fast Break sits in the middle of the range, so it works both as a first Boston Celtics jersey and as an addition to a collection you already have.
Is the Boston Celtics jersey too warm to wear indoors?
Not for long. The Boston Celtics jersey knit is light and the body panels move heat out, so it stays comfortable in a warm room, and the sleeves are cut short enough that it never feels heavy.
Is the Boston Celtics jersey cut for a heavier build?
The sizes run across the standard chest measurements, so there is room in the body without the shoulders pulling. If you are between measurements, take the larger size for a Boston Celtics jersey that sits comfortably.
Will the Boston Celtics jersey keep its shape after a few washes?
Yes, provided you keep heat away from it. Cold wash and air dry and the collar of a Boston Celtics jersey will still sit flat a year later.
Does the green Boston Celtics jersey stretch?
There is a small amount of stretch in the knit, so it moves with a sprint and settles back afterwards. It is not a fully elastic fabric, so a Boston Celtics jersey keeps a proper shape rather than clinging.
Short answersShort answers+
Can I put the Boston Celtics jersey in the tumble dryer?
You can, on low, but air drying is better. Heat is what moves the fibres of a Boston Celtics jersey and flattens the green over time, and it is the fastest way to make a good shirt look tired.
Is the Boston Celtics jersey suitable for a fan who travels a lot?
Very. It packs flat, it barely creases, and a green Boston Celtics jersey still looks right when you arrive. For a supporter who follows the Boston Celtics around, that matters more than most of the spec sheet.
