Looking at a Mammut lightweight synthetic jacket, Eigerjoch Pro IS. Any experience of how they size? Am usually L, something is makimg me think I should go for XL here.
I'm 6ft and 75 kg, approx 41" chest, mammut size L fits me like it's tailored, whereas US size L is way too big. Their Eiger Extreme line which includes the garment you want is particularly slim fitting.
