The Danish national team will use a white name and number set for the home and third jersey, and a red name and number kit for the away jersey.
Nothing unusual about that. The printing is a carry over from EURO 2020 (which took place in 2021).
Contrary to club jerseys the national team jerseys come with a small number to the front.
The back is fairly similar to that of club jerseys. Name at the top. Number below.
The name KJÆR and the single number 4 is a pretty straight forward affair. Letters and numbers are plain white with a tiny silver lining. Due to the monochrome jersey design the printing gets to play an important role with this jersey.
