The Arsenal look has survived coaching changes, roster turns and uniform tweaks. This training jersey carries it forward with Martinelli named on the back.
The body is cut a touch longer in back, which is what keeps it put through a standing ovation. The hem sits a touch longer in back for coverage.
Fan-version build with the Arsenal colourway and Martinelli lettering applied front and back — the detail that separates it from a plain team tee. Every order is checked before dispatch and travels with end-to-end tracking. The colourway is matched to the on-field look rather than to a screen approximation.
It reads as Arsenal gear anywhere, but the palette points straight back to London, England and Emirates Stadium.
How the Retro Cut Fits
US youth sizing (youth S–XL). The cut is relaxed rather than slim, so there is room to move and room to grow. The usual letter size is the right starting point.

Frequently asked questions
What if the jersey does not fit when it arrives?
You are covered by our 30-day hassle-free guarantee with zero restocking fees. If the fit is not ideal, contact our support team and your first size exchange is completely free.
Can this retro kit be worn for casual summer wear?
Yes. The lightweight breathable mesh makes it a staple for warm-weather viewing with friends, five-a-side matches, or casual streetwear.
What size Arsenal jersey should I order if I am between sizes?
US letter sizing runs true. If you want a relaxed layer for cold-weather games, take the size up; for a closer fit take the smaller one. The first size exchange is free either way.
Will the fit work for layering over a hoodie in cold weather?
US letter sizing with a relaxed chest and shoulder cut leaves room for a hoodie or thermal underneath without pulling at the seams.
