Youth Boston Celtics Jaylen Brown Kelly Green Fast Break Replica Player Jersey - Icon Edition

Team details

Boston Celtics colours are the whole point here, and the kelly green base keeps them sharp whether you are at the ground or on the sofa.

Because it is a Youth (kids) cut, the easiest way to get the fit right is to measure a jersey you already like and compare it with the chart.

The people wearing it

Basketball shirts are judged on how they look off the court as much as on the team graphics, so the content that earns its place is history and comparison: what changed between eras, which colourways sit together, and which series collects best. The buyer is usually young, follows a specific player, and wears the shirt with everything else in the wardrobe.

Details that matter when choosing this Boston Celtics jersey

The Boston Celtics Fast Break jersey is the base piece of the Celtics range: the same icon edition colourway, number placement and lettering fans expect, cut in a shape you can wear all day.

Everything starts with the Boston Celtics jersey - it sets the colourway, the fit and the look the rest of the range is built around.

Shoppers filtering by NBA basketball jersey will find this alongside every other NBA basketball top we stock, in the same sizes and the same fit.

If you are shopping Celtics streetwear jersey, the deciding factors are usually fit and occasion rather than specifications: this one is a relaxed fast break for kids and teenagers, cut to be worn regularly instead of once a season.
