Celtic FC / Umbro / 1998-99 Away / Long Sleeve
Umbro Original / Black & Neon Lime / Men's Medium / Vintage 1990s
One of the most striking kits of the 1990s Scottish Premier League era, the Celtic 1998-99 away shirt in deep slate-black and electric lime remains a landmark Umbro design — and the long-sleeve version is the one collectors genuinely struggle to find.
This is a genuine Umbro-made Celtic FC away football shirt from the 1998-99 season, presented in the iconic all-black body with neon lime-green horizontal stripe detailing and matching v-neck collar and cuffs. An all-over sublimated Celtic crest pattern runs across the body and sleeves, giving the shirt a depth and texture rarely seen in kits of this era. The embroidered club badge sits on the left chest, with the Umbro diamond logo and lettering across the front.
This is the long-sleeve cut — significantly rarer on the secondary market than the short-sleeve equivalent and consistently more sought-after by collectors. It wears as a men's Medium, measuring 21 inches pit to pit. No name or number has been applied to the back.

This shirt presents genuinely well for its age. The all-over sublimated Celtic crest pattern is clear and undamaged across the body and sleeves. The embroidered club badge on the chest is sharp with no loose threads, and the Umbro diamond logo and lettering are fully intact.
The internal care label shows some light fraying at the edges, consistent with normal age and laundering over 25 years — this does not affect the outer garment in any way. No significant staining, fading, holes or damage is visible to the outer fabric.

How do I know the size is right for me?
This shirt measures 21 inches pit to pit, equivalent to a men's Medium in modern sizing. Vintage Umbro cuts can run slightly different from today's athletic fits, so we recommend comparing the pit-to-pit measurement against a shirt you already own rather than relying on the size label alone. Feel free to message us if you'd like any additional measurements.
Is this a genuine vintage original or a reproduction?
This is a 100% original Umbro-manufactured shirt from 1998, not a replica, re-issue or third-party reproduction. The construction, label detail and fabric are consistent with genuine Umbro production of that era.
How should I care for this shirt?
Hand wash gently in cold water, turning the shirt inside out to protect the sublimated pattern and outer fabric. Air dry flat or on a padded hanger, away from direct sunlight. Do not tumble dry. This will preserve the colours and fabric integrity for years to come.
Can I see more photographs or specific areas in detail?
Absolutely — message us through eBay and we will be happy to send additional close-up images of any area you'd like to inspect before buying.
What season did Celtic wear this kit?
