Celtic Jersey Buying Guide: Hoops, Heritage and Fit

Few shirts in world football are as instantly recognisable as a Celtic jersey, with green and white hoops that have barely changed in more than a century. This guide covers the history behind those hoops, how the modern adidas kits actually fit, and what to look for whether you want a current shirt or a vintage classic.

Why the Celtic jersey still turns heads

Most clubs have redesigned themselves half a dozen times since the 1980s. Celtic have not. The hoops are one of the few kit designs in football that works without a single trick, and that simplicity is why a Celtic jersey sells in Dublin, Boston, Sydney and Tokyo as readily as in Glasgow, and why it stands with the all-time greats in our round-up of the best Premier League kits of all time. In our wider range of club team jerseys, the hoops are the shirt people spot across a room.

From stripes to hoops: the Celtic jersey's origins

Celtic were formed on 6 November 1887 and played their first match on 28 May 1888, beating Rangers 5-2. That side did not wear hoops: the original kit was a white shirt with a green collar and black shorts. In 1889 the club switched to green and white vertical stripes, and wore them for 14 years.

The hoops arrived in 1903, first worn on 15 August against Partick Thistle, and they have been the Celtic jersey ever since. The socks took longer to settle: black until the early 1930s, then green, then the plain white standard since the mid-1960s. The crest started as a Marist Brothers badge, a green Celtic cross inside a red circle, before a four-leaf clover version appeared in the 1930s. It did not reach the shirts until 1977.

The Lisbon Lions and the shirt that made history

On 25 May 1967 at the Estádio Nacional in Lisbon, Celtic became the first British club to win the European Cup, beating Inter Milan 2-1 in front of 45,000 people. Sandro Mazzola put Inter ahead from the penalty spot inside the opening ten minutes, Tommy Gemmell levelled just past the hour, and Stevie Chalmers turned in the winner late on. Billy McNeill lifted the trophy, and the squad became the Lisbon Lions, a team whose players were all born within 30 miles of Glasgow.

The shirt has been revisited repeatedly: New Balance produced Lisbon Lions 50th anniversary home and away shirts for 2017-18, and adidas marked the 60th anniversary on the 2026-27 away kit with anniversary lettering and a white star above the crest. If you like a shirt with European history stitched into it, our list of the best Champions League kits of all time is a good companion read.

Celtic's kit makers: from Umbro to adidas

Celtic's kit history is unusually stable. Umbro supplied the club from 1937 to 2005, close to seven decades. Nike took over from 2005 to 2015, New Balance held the contract from 2015 to 2020, and adidas have made the kits since. The partnership has since been extended long term, with reported figures well over £30 million covering playing and training kit for both the men's and women's squads, so the three stripes are not going anywhere soon.

The current era has leaned into heritage. The 2026-27 away shirt uses dark green and black vertical stripes with serrated edges between the panels, a tonal horizontal texture, a black wrapover V-neck and white Three Stripes across the shoulders. Launch details are always posted on the official Celtic FC website.

Shirt sponsors through the years

Sponsors are the quickest way to date a Celtic jersey. CR Smith were on the front from 1984 to 1991, Peoples Ford took over for 1991-92, then CR Smith returned from 1993 to 1997. NTL followed from 1999 to 2003, Carling from 2003 to 2010, Tennent's from 2010 to 2013, Magners from 2013 to 2016, and Dafabet have been there since 2016.

If you are buying with one eye on resale, the sponsor often decides value: a shirt from a trophy-winning season outpaces a quiet year. More on that in our guide to which football shirts gain value.

Numbers on the shorts: Celtic's great kit quirk

Here is the detail that catches out new collectors. Numbered shirts became compulsory in Scotland in 1960, and Celtic were the last British club to fall into line. Chairman Robert Kelly insisted the hoops should not be spoiled, so the squad numbers went on the shorts instead. Numbers appeared on shirts in European competition from 1975, but domestically the tradition survived until the Scottish Football League required shirt numbers for 1994-95. Celtic added them to the sleeves first, and only later to a white patch on the back.

Practically, that means a genuine pre-1994 league shirt has a clean, unbroken back. A vintage hoops shirt with a big printed number is either post-1994, a European-issue shirt, or not what the seller claims. Our walkthrough on how to spot counterfeit football jerseys covers the other checks.

Authentic vs replica: which Celtic jersey to buy

adidas splits the range in two. The authentic shirt is the one the players wear: slim fit, jacquard fabric, heat-applied crest and Climacool+ ventilation. The replica uses an interlock fabric, standard Climacool and an embroidered crest, and costs noticeably less.

For most people the replica is the better buy: more forgiving to wear, with an embroidered badge that looks richer up close, and it survives a wash cycle better. Go authentic if you want the match specification or you are building a collection. We compare the two in detail in authentic vs replica football jerseys and in our player version vs fan version buyer's guide.

Getting the sizing and fit right

Fit matters more on a hooped shirt than a plain one, because horizontal bands draw the eye across the body. The adidas authentic cut is genuinely slim, so most buyers should size up one from their usual t-shirt size, while the replica is cut more generously and usually fits true. Measure a shirt you already own flat across the chest, pit to pit, and match that number rather than a letter. Our football jersey size guide has the measurements laid out, and the FAQ answers the usual questions about delivery and returns.

Retro and classic Celtic shirts worth collecting

Three Celtic jerseys come up again and again with collectors. The 1987-89 Umbro centenary home shirt, worn with CR Smith on the chest, is the sentimental favourite. The late-1990s Umbro shirts have aged well and are still findable at sensible money, and the 2017-18 Lisbon Lions anniversary pair by New Balance has quietly become the modern one to own.

Browse our retro jerseys and classic jerseys for the vintage end of the market, and read the best retro football jerseys to collect before you commit. Settle one thing first: whether you want an original or a modern reissue, which we unpack in retro vs reissue football shirts.

Spotting fakes and caring for your hoops

Hoops are unforgiving on a counterfeit. On a genuine shirt the green and white bands line up across the side seams and where the sleeve joins the body, whereas on a fake they step up or down by a few millimetres. Check the crest stitching too: the four-leaf clover should be crisp, with no loose threads bridging the leaves.

Washing is simple: cold, inside out, no fabric softener, no tumble dryer, and never an iron on the crest or sponsor. Our guide on how to care for your football jersey goes through it properly.

Ready to pull on the hoops?

A Celtic jersey is one of the easiest shirts in football to recommend: the design is timeless, the history is extraordinary, and whether you buy an authentic adidas shirt or a 1990s Umbro classic, you end up with something people recognise instantly.
