Animals wear fur on the outside because they have to, why do humans?

Having an outer barrier to wind and a trapped air space inside is the best way to insulate. It's axiomatic for insulating buildings. Impermeable skin on the outside and fur on the inside seems more effecient than fur on the outside. It seems to me that you could wear a less effective insulator, turned inside out as it were, that would weigh less. Why don't people that use animal skins for insulation do this?
