Youth Oklahoma City Thunder Isaiah Hartenstein Blue 2025 NBA Finals Champions Fast Break Replica Player Jersey - Icon Edition
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.

Authentic - Numbered Sizing
36 - 64Some Authentic styles are sold by number instead of letter. The number is the chest width in inches - so a size 48 measures 48 in across. Use the letter column to translate your usual size.

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
Kit for the school run and the driveway, in Oklahoma City Thunder Blue — for the fan who is still growing into the next size.
There is a version of this jersey for the collector and a version for the wearer. This is the second kind. It is the Oklahoma City Thunder jersey in Blue — and it is unmistakably Isaiah Hartenstein’s. The graphics are applied in layers rather than printed flat, so the numbers sit slightly proud of the mesh.
Recycled polyester with wicking treatment — the reason it does not cling or feel damp after a long evening. The collar is a tagless V-neck with taping at the back neck, so nothing scratches during a full evening of wear. It is as believable at a birthday as it is at a tip-off, which is exactly what you want from a jersey. The Blue sits comfortably next to older Oklahoma City Thunder pieces if you already have a collection going.

Questions, answered
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.
Does the lettering match the team design?
It is produced in the same finish and colour-matched to the graphics already on the shirt.
Is it comfortable straight away?
Yes — there is no breaking-in period, and the taped neckline keeps the inside smooth.
