Gap size am winter jacket

This jacket was so great! I bought it about two years ago but haven’t worn it much this year. It has 3 types of pockets (the lower pocket can be accessed by the top or the side - see photos) and you can cinch the waist. It has gussetted sleeves and zips up high on the neck and has a deep hood. I live in the north where winters get pretty cold…up to -30 these days and it holds up to about -20 with a sweater underneath! (I haven’t tested it lower because who the heck goes outside when it’s that cold??)
