1991:
O'Neills began to introduce sleeve chevrons early in the 90s, often featuring county crests. Louth premiered their new style for the surprise win over Mick O'Dwyer's Kildare.
1991:
Next up for Louth were Laois, and for both the drawn game and the replay loss, the name of Allied Irish Beef Processors, who had a plant in Dundalk, was on the jerseys.
1992-93:
Subtle changes to the jersey, with the collar now carrying red trim, the white shoulder piping absent and the AIBP wordmark larger. A new crest was also introduced.
1993-95:
Long-sleeved version, though without white piping or collar details.
1994:
Shoulder piping returned and AIBP logo bigger, now carrying the word 'Dundalk' underneath.

After wins over Westmeath and Carlow, Louth were given a brand-new strip for the Leinster semi-final against Dublin, featuring O'Neills' new 'Páirc' sleeve design.
1995:
A reversion back to the older design in the league in 1995, though with the GAA's new logo now included.
1995:
Another new style, which O'Neills christened 'Three Vs', used against Kildare and Dublin in the championship. The AIBP logo was also updated.
1996-98:
Long-sleeved edition of new jersey, first seen against Wicklow in 1996 O'Byrne Cup.
1996-97:
Slight change as the O'Neills name replaced the Guaranteed Irish logo.

1999-2002:
New jersey in long sleeves, used in the league games during the autumn and in subsequent seasons.
2002:
Subtlest of changes, an extra white stripe on the outside of the collar.
2003:
Waterford company Azzurri received a licence to produce county strips for 2003, and Louth were one of the counties to sign with them. A long-sleeved jersey was used first, in the O'Byrne Cup and the league.
2003:
Short sleeves were first worn in the league game against Limerick in March. While it was a nice design, it was a bit busy around the armpits.
2004:
Louth's long association with AIBP ended at the end of 2003 and the new sponsor was bookmakers Boylesports. While their logo initially appeared in such a way to make it look like it was covering AIBP, these were actually new shirts as the lack of cuffs showed.
2004-05:
For the league game against Wicklow in February, Louth appeared with the 'proper' Boylesports logo on the long-sleeved shirts.
2004:
Short-sleeved version of jersey with Boylesports logo.

Louth changed their crest in 2005, and in addition the neck of the collar on the shirt was altered.
2006:
After three years, O'Neills returned as gear manufacturer and kitted Louth out in a two-two red number.
2007:
Another new jersey was required as the Boylesports deal ended, to be replaced by McCabe Builders.
2008:
Front numbers added.
2009:
GAA logo changed to reflect association's 125th anniversary.
2010:
A new, smart, design from O'Neills, but it wouldn't last long...
2011-12:
...as the penny finally dropped that the Boyne Bridge on the 2005 crest was in fact in Meath, so a a change was required. A stylised version of a St Brigid's Cross, incorporating the county name in Irish, was the new choice.
2013-:
As Louth's agreement with McCabe ended, a new deal was struck with Morgan Fuels, who had previously sponsored Armagh.
1997:
Worn against Cork in a league play-off in '97, though likely to have been used before that too.
2001:
Long-sleeved version of the '97 shirt, worn against Galway in the league.
2002:
New change jersey, mixing O'Neills' Brandon torso design with the sleeves from the red jersey. As far as can be ascertained, it was only ever worn against Armagh in the GOAL Challenge after the Orchard County won the All-Ireland in 2002.
2007:
New design to match the jersey launched when McCabe became sponsor. Worn against Armagh (league) and Cork (All-Ireland qualifiers).
2013-:
Revealed along with the new red shirt, this is one of the best things O'Neills have done in recent times for our money, though the sponsor intrudes slightly.
