I think its more to do with air pockets not layers, I was in Norway in -40 degress in the army and the best equipment we had was fishnet long johns! full of airpockets and toasty! British Issue stuff was layered but no air pockets.

Lebarca wool blankets
In the Columbian Exchange, woolen Navajo blankets were brought to the Americas from Europe, Asia, and Africa.
Wool is a better insulator than cotton because of its natural crimp, which creates air pockets that trap heat. This insulation helps to retain body heat and keep you warm. Additionally, wool fibers can absorb and release moisture, helping to regulate body temperature and keep you comfortable in a wider range of conditions than cotton.

It's warmer
Two thin woollen blankets are warmer than one thick woolen blanket because the air trapped between the layers of the two thin blankets provides extra insulation, helping to retain body heat more effectively. This trapped air acts as a barrier against the cold air outside, keeping you warmer.
For infection prevention puposes, just think what could potentially be hiding amongst the woollen fibres!
The Anasazi traded many things such as animals, pottery, beads, turquoise and a number of other things.
Both of these industries no longer exist in the UK. When they were active, Lancashire was well known for its cotton mills and Yorkshire for its woollen mills.
