my favorite is light fleece under medium wool,,,, if you put off a stink then you always will stink thats all there is too it,, when its normal or faint your used to it and don't smell it but when its bad you'll notice it but it is ALWAYS there my friends ah ha ha ha ha...
I'd say only one would be at least a 22oz wool shirt or jacket,, depending on the weather theres either a vest over that or flannels under it..
also I've spent a day in the Pouring rain in around 40 degree weather wearing a Filson Double Mackinaw jacket just to see how it felt and yeah it may not get cold enough where you'll freeze to death but it isn't a camp in the park either it actually was pretty miserable with the water going right through and then dripping down my body right into my socks and boots,,,, I'd take a nice rain coat over any of my wool jackets when rains in the forcast anyday.
so if there was more choices and i could only have one fabric and it was a matter of survival in all elements of weather,, after wearing Good wool for 15yrs which i still wear everyday I'd look into something else.
