The sizing chart and comments are way off. I'm 175cm, weight little under 70KG and ordered an XL because they suggest to add two sizes (I normally wear a size M). This sweater is so large it gives me "bat wings" under my armpits. The hoodie is also enormous compared to my head. FYI: The sweater is also worn by someone else who has a size XL for pretty much all their clothing and they also had those "bat wings". Other than that it seemed to fit. I can't confirm it (yet), but by the looks of it I think a size S would suffice for me.
Love the item, 6’5” 265 lbs, fits perfectly. The material is soft and seems well made.
