I typically wear XL in the US. I was told from support to get a 2XL since their shirts are made in Europe. I ordered the 2XL and it took about a good three weeks for it to arrive. I was so stoked to wear it. Once I wore it, it was extremely large especially on the sides - it was wide. Felt like I was wearing a dress shirt. The fabric was very thin. You can see through the shirt. I don't know. I was expecting much more but it led me disappointed. I don't think I'll get a shirt from them again.
