In reply to Andy Mountains:
ive got the Large size and am 5,9. 43" chest and 34waist. it comes up quite big on me with a microfleece underneath but great for throwing over all my layers and hardshell when standing about.
Ive got last years model so weather the sizes will differ slightly this year im not sure. I did notice quite a price increase this year. not good as its starting to get closer to bigger brand names offering same or similar specs. im sure it will be still a good buy though!
