From parcel to match day
01
Start with colour, then the cut
Relaxed enough for everyday wear, close enough that the Boston Celtics Fast Break jersey in white does not look like borrowed clothing.
02
How the Fast Break is put together
a properly finished neck on the white Boston Celtics Fast Break jersey is the difference between a Fast Break that looks retail and one that looks made. Everything on this Boston Celtics jersey that you can see from the concourse is applied flat, which is why the finish looks the same after a season.
03
How the jersey sits on you
This Boston Celtics Fast Break jersey in white is cut true to size with a touch of ease at the waist, which is where an adult needs it most. For a Boston Celtics supporter who is between two sizes, take the larger one and the jersey will sit the way it does on the models here.
04
The match-day test
For an adult who wears their Boston Celtics colours with pride but also wants the Fast Break to look considered, this white version is the balance. The Boston Celtics Fast Break jersey in white works for an adult who is at the game, at the bar afterwards and on the sofa later, and it looks right in all three.
a good Boston Celtics jersey is one you do not think about once it is on, and the white Fast Break is built with that in mind.

Feel and finishPolyester knit, true to size+
a breathable knit that moves with you rather than against you, finished with a soft hand feel that keeps the Boston Celtics jersey comfortable from the first wear onward. 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.
It works as a gift because the size is a known quantity, the fit is standard, and the Boston Celtics colours is a colour the recipient will actually wear rather than store.

Care and orderingWashing, returns and support+
There is no special treatment for this Boston Celtics Fast Break jersey. a cold cycle and a hanger is all a white jersey needs. Following the cold wash and the line dry is the difference between a Boston Celtics jersey that holds its shape and one that does not.
The Boston Celtics Fast Break jersey in white is packed so that the size you chose is the size that comes out, and if it is not we will fix it.
Questions before you order
How should I wash a Boston Celtics jersey to keep the size?
Cold wash, inside out, and air dry. Heat and tumble drying are what shrink a knit and shorten the body over time, so avoiding them keeps the Boston Celtics jersey at the size you bought.
What is the best way to dry a Boston Celtics jersey?
On a hanger or flat, at room temperature. A Boston Celtics jersey dried this way keeps its shape, and the white finish stays where it was.
Will the number and name on the Boston Celtics jersey crack?
The graphics are applied so they sit on the surface of the knit and flex with the fabric. They are far more resistant to cracking than a thin surface print, and cold washing keeps a Boston Celtics jersey sharper for longer.
Short answersShort answers+
What arrives in the box with a Boston Celtics jersey?
One Boston Celtics jersey, ready to wear. The white and the cut are set, and if you ordered a custom name and number they are already applied to it, so it goes straight onto the hanger.
Is the Boston Celtics jersey worth buying if I only watch at home?
More than people expect. Watching at home is still a match day, and a Boston Celtics colours jersey makes the difference between watching a game and being at one. It also works for the rest of the week, which a viewing-only gift would not.
