Runs large for a slim fit
Color: Black 02, Size: Large
I followed the size guide and ended up with an item that was to large in all areas. It did not fit like a slim fit. The fabric is odd and does not feel great against the skin. I love the design. I really wish it would have worked.

Not true to size but great quality.
Color: Black 02, Size: Medium
I bought a medium for my son who normally wears medium. It was extremely big. The quality and arm length was good.
