Kids sizes are chest width in inches, not age — the age column is a guide only. Measure a shirt that fits and match the chest figure.

How to measure

Lay the shirt flat and measure pit to pit (armpit to armpit) and collar to hem, then compare with the table. Between sizes, take the larger. Measurements are in centimetres, with 1–2 cm variation between pieces.

About this shirt

The Athletic Bilbao third shirt from 2025/26 — kids sizing. Sizes 16-28. Worn in La Liga.

Carries the Kutxabank sponsorship, in place at the club since 2015.

Third kits are made in far smaller runs than home or away, and are usually the season's most adventurous design because they carry the least expectation.

The away, away and goalkeeper from the same season are listed separately, and we also hold the third shirt from 2024.

A new-season kit.

Athletic Bilbao in the archive

Home, away and third kits, plus goalkeeper shirts, kids kits and training wear, with retro seasons making up most of the range. Red and white vertical stripes at home. Eight La Liga titles. Our range spans 1986 to the current 2026/27 kits and leans retro — over half of the Athletic shirts we hold are from past seasons. Home, away and third kits, plus goalkeeper shirts, kids kits and training wear. Every listing states the exact season.

Printing, delivery and returns

Name and number printing is free on this shirt. Choose a squad player and the number is applied as issued, or send any name and number you want. Printing adds one to two working days before dispatch, and printed shirts cannot be returned unless faulty — if unsure of the size, order it plain and we print it afterwards for the same price. Full detail on the printing page.

Tracked as standard, everywhere — packed flat between card, never folded into a bag. Allow 7–14 days from order to delivery.

Service	Time	Cost
Standard tracked	7–14 days	£3.95
Orders over £30	7–14 days	Free

The same rate applies to every country: free over £30, otherwise £3.95, tracked, in the same 7–14 days. Orders outside the UK may attract import duty on arrival, which is the customer’s responsibility. Full tables on the shipping page.

30 days from delivery to change your mind — longer than the 14-day statutory minimum. Email hello@shirt-archive.com with your order number before posting anything back; send it unworn with tags attached, and the refund goes to the original payment method within five working days of arrival. If we sent the wrong thing, postage is on us both ways. Full policy on the returns page.

Common questions

Which season is this Athletic Bilbao third shirt from?

This is the 2025/26 third shirt. The season is stated on every listing and on the order confirmation, so what arrives is the season named here, not a current substitute.

How does kids sizing work?

Kids sizes run 16 to 28 and are chest width in inches rather than age. The chart above maps each size to an age as a rough guide; measuring a shirt that currently fits is more reliable.

Can I get a name and number printed on it?

Yes — free, applied before dispatch, which adds one to two working days. Printed shirts cannot be returned unless faulty, so if you are unsure of the size, order plain and we print it afterwards for the same price.

How quickly will it arrive?

Allow 7–14 days from order to delivery, everywhere. Standard tracked is £3.95, and orders over £30 ship free to every country. Everything is tracked, including international.

Is this the exact design worn in 2025/26?

Yes — this listing is the 2025/26 third design specifically, not a current shirt standing in for it. If we hold the same design in other cuts they are listed separately.
