I'm having a hard time resisting the MEC Northern Lite Ultra at $95 (plus U.S. shipping):
The problem is I don't have any experience with how their jackets are sized, especially outer layers such as this. A patagonia DAS worked for me in size medium, but was too boxy. I am 6', 170 lb, 40" chest, which means if the medium is sized to go over a few layers (R1, windshell, nanopuff), it'll be perfect, but if not it's going to be too tight. Returns would be a hassle as I don't live in Canada.
Any have experience with their sizing?
