Those Under Armour compression shirts from the beginning of the century were all unicolor, but unlike other manufacturers, who could only think in black, grey, navy, dark green or other dull colors, Under Armour right from the beginning made their shirts in a wide range of loud colors, officially so that every football team could have a shirt in the right colors of their club. While for me as a non-football player but only an admirer, it was a good way to put some color on my body.
