The 2015 Kerry jersey dispenses with the traditional collar for the first time ever, but otherwise it is a fairly uncluttered design. The socks with three large gold hoops call to mind the distinctive style used when adidas were the manufacturers in the 1980s and again from 1998-2000. 

The alternative is the traditional blue, but continuing the hoop motif from the normal shirt as royal and navy blue are mixed in a pleasing fashion. The hoop is also present on the goalkeeper shirt, making a change from the usual solid gold.

With Millfield going out of business, adidas saw an opportunity to return. However, despite getting a Dublin firm to produce the kit under licence to comply with the rules, the GAA wouldn't allow the German company's logo to appear on the kit itself.
Eventually, the GAA relented and allowed the adidas logo to appear on the on-field gear. This version was seen in the All-Ireland semi-final loss to Kildare.
For the 1999 championship, a different shorts style was used, with three gold stripes on a green background.
After a long gap, O'Neills returned as the Kerry jersey manufacturers with this nice effort, featuring elements of the Kerry crest on the sleeves. The shorts were very similar to the second adidas design.
Long-sleeved version of the new O'Neills kit.
Evolution rather than revolution where the new jersey was concerned. Additional sleeve trim and a green/gold gradient near the collar distinguished the new kit from its predecessor.
Long-sleeved version, bottom part of the sleeve plain green with lower gold stripe removed.
Long-sleeved version, lower part now in gold while the trim continued all the way down.
The new jersey launched for the 2006 bore strong resemblance to the adidas top of the early 1990s with its gold sleeve panels. Another notable change was the predominance of green on the socks, which were usually hooped.

Noticeably darker than the previous kit and not featuring as much gold, this looked more like a traditional Kerry jersey. Predictably, its first year was greeted with yet another All-Ireland football win.
Long sleeves, including the new GAA logo commemorating the 125th anniversary.

Long sleeves, GAA logo changed.
Kerry launched a new crest in November 2011 so it was no surprise when a new jersey followed soon after.
For the first time in a long while, the Kerry shirt didn't have a proper collar. Otherwise, the changes were fairly slight, the socks are a nice throwback to the 80s. Initially worn with a basic shorts design.
A newer shorts style, tying in with the shirt, was introduced for the 2015 championship.
When adidas returned, the new goalkeeper shirt was noticeable for the inclusion of green sleeves for the first time.
The adidas logo was finally allowed to be added for the All-Ireland semi-final clash with Kildare.
Change to shorts style.
The new O'Neills goalkeeper's jersey followed the design of the outfield one and featured the same sleeve design.
Long sleeves.
The 2000 Munster football final pitted Kerry against Clare. Declan O'Keeffe wore this, a blue body with the same sleeves as the regular shirt.
When Kerry wore white against Meath in the 2001 All-Ireland semi-final, the goalkeeper's jersey used the same sleeves with the body in solid green.
This blue jersey was originally intended to be Kerry's change jersey from 2000 but was only used by goalkeepers. Called into action for the Meath league game in 2002, paired with green shorts.
For reasons unknown, in 2002 O'Neills issued goalkeeper shirts which had plain collars, devoid of trim.
In the early part of the 2000s, most counties' goalkeeper jerseys had the same sleeves as the outfield tops, though Kerry differed slightly in this regard, and green side panels were also used.
Long-sleeved version, essentially just welding on a solid gold section as the green part ended abruptly.
Change blue shirt with regular shorts, worn against Roscommon.
For 2005, the sleeves of the outfield jersey were used on the goalkeeper's strip.
Kerry wore blue shirts and shorts against Offaly in 2005 and goalkeeper Diarmuid Murphy also swapped his shorts even though there was really no need.
While it did not follow exactly the pattern of the green jersey, this goalkeeper's strip had much of the trappings of the new introduction, in a year when Kerry again beat Mayo in the All-Ireland football final.
The final outing for this came seven years after it was made, in the league game against Dongal - where both counties wore their normal shirts, making for a bad colour-clash.
Front numbers added.
Essentially the regular Kerry jersey minus the hoop, this netminder's shirt was used against Donegal in the league and also against Clare in the championship.
Long-sleeved variant of 2006 goalkeeper shirt.
Initially, the navy set of change jerseys was supplied with this GK top, but gold was a poor choice as it could not be used against Donegal - Ger Reidy wore a regular Kerry shirt with number 27 on it instead.
No problems, though, with the new 'normal' goalkeeper shirt being its usual gold.
Short-sleeved version.
The next time the navy shirts were used was against Meath in the All-Ireland semi-final; this time, white was a more sensible choice for the goalkeeper's shirt.
Change to GAA logo.
Identical to the 2009 shirt apart from the GAA logo.
Change shorts worn against Limerick.
Change shorts and socks used against Mayo.
New shirt for 2012, following the stylings of the outfield one.
White and blue version to match the change kit.
In the All-Ireland final against Mayo, Kerry goalkeeper Brian Kelly had to switch from his usual gold and wore this, like the change top but with green replacing blue.
For the first time, the goalkeeper's shirt was a full reversal of the outfield top, featuring a green hoop.
New shorts added for 2015 championship.
Previous change shirt, worn with new shorts and socks against Clare in the McGrath Cup.
The record All-Ireland senior football champions have had a rich and varied kit history and the Kingdom have been trend-setters in a lot of areas, not least their dalliances with adidas.

The current kits mix modernity with nods to the past and are thankfully free of too many superfluous design elements.

A league clash with Meath meant the need for a change. This adidas offering followed the design of the home in blue but without the hoop.
Kerry advanced to meet Meath in the national league semi-finals, but the deal with adidas had expired and so there were no new change shirts available. This set was found and worn, with the shorts sponsorship and lack of GAA logo dating it to pre-1994.
When Kerry met Meath in the 2001 All-Ireland semi-final, it was decided to use a new white jersey with green shorts. It's a commonly held misconception that the white shirt was jettisoned after the heavy loss...(see next)
...but it was also used in the 2002 league semi-final against the Royals, albeit with slightly different shorts. Kerry avenged the semi-final loss but the shirt was not worn by the seniors again.
When Kerry met Offaly in the league in 2005, the Munster jersey of that period, featuring the Kerry markings, was worn. Blue shorts were also a feature, though the socks remained unchanged.
When Kerry met Donegal in the league in 2007, neither side changed jerseys, but the following year both did. Donegal wore the Ulster colours while Kerry lined out in blue jerseys that featured the sleeves of the regular top.
This intimidating kit, darker than previous change jerseys, saw two outings in 2009. In the first, a league game at home to Donegal, different shorts but normal socks were used.
For the All-Ireland semi-final against Meath, navy socks were used.
While meetings between Kerry and Limerick rarely called for a change in jerseys, this was ordered in the 2011 All-Ireland quarter-final. The same kit as 2009, though with a change to GAA logo, different shorts and regular socks.
Kerry had to change again for the All-Ireland semi-final against Mayo, who wore red. Following complaints from the players that the navy shirts were hard to see in the Limerick game, a lighter shade of blue was used, though with navy and gold socks.
Similar to its predecessor, in the same style as the green and gold but with no hoop.
Again, the design followed the 'home' in blue, though with the addition of a navy hoop for the first time. One slight difference to the green shirt was extra gold trim on the sleeves.
