Not as bulky as down parka. I really wanted to have a parka not a jacket. Tried 1 parka but had to return as the underarm area was too tight that I couldn't raise my arms. This parka is not a down parka but quite warm. Underarm area (i.e., upper chest room) is good that I can raise my arms and have no issues of moving around. Only 1 down side is the pockets (the lower ones) are not 100% open but only the front part opens with velcro. Not a bid deal but would have been much nicer if the pockets open fully.
