This is the new AIK football Vadersolstavlan design shirt 2023, a special, limited edition kit for Swedish club AIK made by kit partners Nike. The jersey made its on-field debut in AIK’s Swedish Cup clash against Vasteras a few days ago- the game ended in a 1-1 draw.
The predominantly white shirt features a Vadersolstavlan (Sun dog painting) design on the front- one from the 16th century that is widely considered as one of the oldest depictions of Stockholm.
