My Wiggys Arctic parka. Genuinely breathable in my personal experience, and as comfy and warm as any down parka, no matter how expensive. Major difference is that it keeps warm even if wet, dries out very quickly and can be thrown in the washer when dirty as I've done on a number of occasions (once you zip off the genuine fur hood trim). Got it in a sale a couple of years ago, and emailed him to ask if he did it in 3xl, as it wasn't available in that size on the website. He made one up for me at the sale price. His manner may be abrupt, but he delivers the goods! (Proper double YKK no 10 zip, too)
The Swedish M90 is brilliant value, although try to get the version with the quilting in the attached hood. Much better than the later version (and yes, I have both versions). I also like the US Army fishtail parka, particularly if you button in two of the quilted linings. Both the M90 and fishtail parkas are pretty heavy though, even heavier if wet, and take a long time to dry out.
