Your sizing is inaccurate. I'd like to see sizing recommendations for people with a significant amount of upper body muscle mass. I recently purchased a size L ascend rain jacket based off a chest measurement of 103 cm however the shape of the garment was far too tight across the chest. Furthermore i was unable to fit my arms into the sleeve as they are too narrow.
This sounds absurd but this can be solved by adding some more info to your sizing chart.
