It's not about how many layers of clothes they wear, it's how the layer is made. In Antarctica, each layer of clothing is usually several other layers stitched together to keep as much heat heat as possible. It also depends on what material is used. During my year at South Pole Station, my outdoor clothing would be a parka, button-in liner, wool shirt, thermal underwear. The parka had a outer shell, insulating filler, inner shell - so that is 3 layers right there. The liner was also 3 layers. So there were usually 8 layers of material plus trapped air pockets between my skin and the very cold environment. It was about the same for the footwear.
It will be made of many components the casing material will not matter much.
