The reason for Linz to release special international jerseys is that their usual kits are not allowed due to UEFA's kit ...rules (they feature pinkish sleeves because of the sponsor BWT). However, that is not all. The kits are made by sponsor BWT (Best Water Technology, an Austrian manufacturer of water treatment systems - they started with a new equipment line for the kit to bypass UEFA rules. The Linz European home jersey combines the club's traditional colors - white with black, used for the pinstripes. It is a much more classic design than the league home kit.On the left chest is the logo of 'kit maker' BWT, while the logo of beer company Zipfer is on the front. The flag of the club's home region, Oberösterreich, sits in the middle of the chest area.
