Cooper Flagg Dallas Mavericks Unisex 2025 NBA Draft First Round Pick Swingman Jersey Icon Edition 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
Cooper Flagg in the Dallas Mavericks colours — built for nights that run long.
Think of it as the shirt that lives near the door during the season — easy to grab, easy to wear, easy to wash and put straight back on. It is the Dallas Mavericks jersey in Blue — and it is unmistakably Cooper Flagg’s. It is a knit rather than a woven fabric, which is why it moves with you instead of against you.
The knit is recycled polyester with a wicking treatment — the reason it does not cling after the fourth quarter. The collar is V-neck, taped at the back and free of labels. Give it in December, wear it in June: the design does not date with the season. It is the kind of shirt that ends up photographed more than most — worth knowing before you pick the colour. It is the kind of shirt that gets borrowed — worth knowing before you buy one for somebody else.
