Cooper Flagg Dallas Mavericks Unisex Swingman Player Jersey Association Edition White
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
The Dallas Mavericks jersey built around Cooper Flagg — the sort of jersey that ends up in the weekly rotation.
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. The design keeps the Dallas Mavericks look clean and puts Cooper Flagg where you would expect. The finish is layered appliqué rather than a flat print — a small difference you notice the first time you pick it up.
It is knitted, not woven, and the wicking finish is what keeps it comfortable late in the game. The collar is a tagless V-neck with taping at the back neck, so nothing scratches during a full evening of wear. It pairs with jeans, shorts or whatever is clean, which is most of why it gets worn weekly. It layers under a hoodie without bunching at the shoulders.
