I just received the Hemisphere jacket and have only worn it one day at the Ski Area. It is lighter than I anticipated for a winter ski parka. The flexible material at the shoulders make mobility very nice. It is designed for use with the comparable bib pants so there is not an inner powder skirt.There are snaps straps that can go with pant belt loops. I have not used it yet on a bid powder day and I do not yet have bibs so we will see if the jacket will ride up alot and if I end up with a lot of snow in the back side.
