I recently came across Pride In The Jersey, a website about the kits of the various county-level GAA teams. This page is particularly interesting as it links to pages for each team with designs for kits dating back up to a few decades. Some of the kits have clearly gone through periods of having better and worse designs, and it’s interesting to see how long those periods have lasted!
I particularly miss the “chevron” era of Clare jersey designs, from 2000 to 2005. As well as having a nice design (featuring plenty of chevrons), I remember jerseys from that era (correctly) having a nice saffron colour in real life – some other Clare jerseys have been a more plain yellow or have had a subtle mix of shades.
