Runs large
Size: Large, Color: Red 09
I really like the quality and the fit. However, I have to say it runs a bit large. I’m usually an XL or even XXL in other brands, but in this case the L fits me perfectly.

Nice shirt in AC
Size: Large, Color: Grey 09
The shirt looks good, fits well, but cannot be used as a golf shirt or something you do physical activity in. Even though it’s polyester, it’s not a dry fit type shirt. It will make you sweat more than you should.
