The best undergarment I've ever worn is the ones used by the Norwegian Army. It's basically some kind of mesh shirt made of wool, which does the job of wicking sweat and warming up cold air between the layers better than anything I've tried. Can be worn under anything. It's not cashmere though http://www.brynje.no/super_thermo_shirt.html Really the best undergarment for any condition you can buy.
