2012-13: While the shirts remained the same as in the previous season, the shorts reverted to a simpler design, devoid of the intruding white stripes. One variation in the Pro12 saw Leinster wear the white socks for the trip to Italy to face Zebre.
The province also reverted to having a separate jersey for European outings. Like its 2010-11 predecessor, it was a lighter shade than the usual shirt and featured silver trim. The shirt was used in all six Heineken Cup pool games (sleeve patches the only variation), but Leinster failed to qualify for the knockout stages.
They did have the consolation of being parachuted into the Amlin Challenge Cup, however. In the quarter-finals of that competition, Leinster faced Wasps and wore white shorts and socks, but the shirts still carried the Heineken logos. For the semi-final and final against Biarritz and Stade Francais respectively, the proper sleeve patches were applied.
