Wool is the warmest blanket material, especially wool from animals who live in cold terrains (see comparison of wool types in my previous article).
Wool is a natural material that includes a crimp, which helps to hold in more heat than a material with an open weave. It also provides natural insulation.
They way in which a fabric holds moisture is also important. Natural fibers like wool, silk and cotton will all absorb water, whereas synthetic fibers like polyester and nylon do not.
Absorbent fabrics will tend to keep you quite comfortable, wicking moisture away from the skin and leaving a layer of warm, dry air.
