I have that kuiu down jacket, that is the warmest most packable jacket I have, the big issue with it, is that it is so loud,
you can't move an inch with out it letting every deer within a mile know your there.
I mean the loudest thing I've ever worn, great if you are glassing in the west at the next mountain for 6 hrs,
but that thing can not be worn in a tree stand, with anything close by
I even tried putting a merino wool pullover over it, and it is still loud, crazy amount of money and I may use it duck hunting only.
did I say loud!!!
