This is the new AZ Alkmaar 50th anniversary home kit by by Under Armour
The new home kit will be used during the 2017–18 Eredivisie season, which is the 62nd season of the top-tier Dutch League Eredivisie since its establishment in 1956.
Again, this could have been a great shirt but the red in the badge is different to the red in the shirt so makes it look like a rip off. Seems to be a common theme for next season's shirts.
