THE NORTH FACEWomen's Freedom Insulated Pant (Standard and Plus Size) - PFAS Free

Is the fiery red actually orange?

Which are more insulated, these women's freedom or the women's sally snow pants?

I am 5’3” 110 lbs. waist 25 hip 33. No reviews to guide me so what size should I order? Will wear fleece tights underneath.

What kind of a button is it? Is it a push in button?
