Cooper Flagg Dallas Mavericks Youth Hometown Fashion Jersey Blue
Size Guide
Everything below is the garment measured flat, not your body. Chest is the full width from armpit seam to armpit seam; length runs from the highest shoulder point down to the hem. Fastest way to get it right: take a jersey that fits you well, measure it the same way, and match the numbers.

Basketball jerseys are meant to hang loose. If you want a regular, closer fit, order one size below your usual.
Go up. The extra room is how the cut is designed to be worn, and it layers over a hoodie in winter without pulling.
Match the numbers to a shirt you already own rather than to your body. Printed names and numbers on the back do not change the fit.

Description
A Cooper Flagg jersey for the youngest Dallas Mavericks supporters — built to survive a school bag and a driveway.
Nobody buys this to leave it folded. It is a shirt for the schedule, not the shelf. It is the Dallas Mavericks jersey in Blue — and it is unmistakably Cooper Flagg’s. The finish is layered appliqué rather than a flat print — a small difference you notice the first time you pick it up.
The fabric is recycled polyester with a wicking finish — drier than cotton and quicker to dry. The neckline is taped and label-free, so it stays comfortable for however long the game runs. The design is restrained enough for everyday wear and loud enough for game day, which is a difficult balance.

Why it gets worn out, not worn out fast
- Layers without bunchingSits over a long-sleeve tee in cold gyms without riding up at the waist.

- Light on small shouldersKeeps it wearable from September bleachers to June driveways.
- Made for daily wearDesigned for the kid who puts it on the moment it is clean.
Before you commit
Is it comfortable straight away?
Yes — there is no breaking-in period, and the taped neckline keeps the inside smooth.
Is it warm enough for winter?
On its own it is a summer-weight shirt; over a long-sleeve tee it works through the colder months.
How does the youth cut differ from the adult one?
Same colours and graphics; the body and sleeves are shorter and the proportions are scaled for smaller frames rather than simply narrowed.
Is the fabric different from the adult shirt?
It is the same recycled polyester knit — the most forgiving weight for school days and weekends.
