I had an old (as in 10+ years old probably) Rab Vapour-Rise jacket in large which has been worn to death. The fit is great for me, really quite fitted around the torso but with enough room in the arms/shoulders.
I've just bought a new Rab Vapour-Rise Summit jacket to replace it in large (i.e. the same size) and it's way baggier around the middle. Previously I've tried Rab stuff in medium and it's always been just far too tight around the shoulders. Has the fit on Rab stuff changed over the years though, is it now generally baggier and less athletically cut?
