In reply to DaveDavina: I find that the current tech clothing is all slim fit, long arms etc. Surprised you are struggling. ME, Rab, Marmot TNF etc all seem to be this way. I'm 6'4 & 13 1/2 st. and my gear fits brill. What size RAB and ME gear is he trying, I'm guessing L is too baggy, and M is too short?... But I have several RAB garments in M admittedly they are a tight fit (but that’s good for layering and function)and are comfy/stretch, but are ok in the arm, and some L as outer layers. Having said that my RAB belay jacket in L is BIG, but that’s the idea?
