i'm not much on blankets but i can tell you that US Army ones
are not that great--more for inside on a cot--Swiss Army??
could be better--the only one i would trust is a Hudson's Bay
blanket--very spendy but a life time sort of thing..at my
cabin i used a LL Bean Trappers Blanket and in a semi heated
room it kept me warm in low 50's temps..
