In reply to lb1dej:
I have the ME Tupilak jacket in a Large and recently bought the Rab downpour plus jacket in a Large but took it back and ordered the medium
I put both jackets against each other (ME Large against Rab medium) and found them to be exactly the same size apart from the Rab was longer in length but was slightly shorter in the arms
I do think jackets vary in size as the Alpine fit ones are a slimmer fit
