I am an 187cm 80kg male, very few muscles and a tiny bit of belly + long arms and M fits perfectly for me! Allthough judging from the other reviews, I think the different colours fit differently! So only use my review as reference if you pick the same colour. The shirt is perfect for running in the Fall/ Mild Winter or as an undergarmin for Winter Cycling.
