Here is a very warm down parka I wish was available when I was looking for one. I did buy an Eddie Bauer Peak XV -30 F. parka on a big sale which I do like a lot. Both parkas are very similar.
After checking with Bean’s product specialist today I was told that ended, this parka DOES have internal baffles. Or as the product specialist called them, “partitions”. Good term for what baffles really do.
For $299  in regular or tall length this is a very good buy for all but truly Arctic -50 F. weather . It is rated by Bean’s as +15 F./ -35 F. so should be great for 90% of sub-zero  North American winter weather.
A Tall size might be a good choice for you if you want a bit of extra length and to keep wrists covered when reaching.. It does NOT say if it is “helmet compatible”. Likely not.
It is made from Pertex Y-Fuse fabric, 850 down with Down Tek DWR treatment. I like down DWR. For as much as you are going to wash this parka (likely 2 or 3 times ever) you ain’t gonna wash much of the DWR off.
