Why the yellow button? 

6AM WorkShirts were originally inspired by cycling jerseys (the idea came on the bike too.) So we thought we'd add a simple and classy detail on our white shirts in form of a yellow top button. This yellow top button symbolizes the greatest achievement possible in cycling. Every year the winner of the Tour De France is awarded the infamous yellow jersey. 

If the yellow button isn't quite your taste, don't worry, we attach an extra white button to the content label of every shirt.
