In reply to top cat:
Yea it's arrived and is a little tight under the arms, not enough to be of issue though.
The jacket fits great in general, nice long sleeves, long in the torso and enough rooms for a thick midlayer, the best for I've found for my height and ape index.
It just rides up into the arm pits a little. I'll try it out this weekend, I'd the armpits chafe too much I'll be able to sell it on and not lose out.
