I have the parka and the pants. The pluses: they are very quiet and warm. The minuses: they are heavy and a bit bulky.
I wear them when I plan to sit in a stand all day when it’s below freezing. As mentioned above you either need to carry them (read bulky above) or really take your time.
While bulky I’m still able to shoot a bow in them. I’ve sat all day in them with temps in the upper teens/lower 20s with only a good baselayer and pants/ fleece top under them.
I would not recommend them if you plan on moving a lot through the day.
