I prefer wool over any other material.

I've always preferred wool for its ability keep me warm even when it's wet. The boiled wool in this jacket is thinner than the heavy "army coat" jackets so it is more flexible and breathable. I use it as a single layer jacket under my gortex shell when skiing as well as everyday use.
