Can I get by in weather that has nights which go down to about 20F (-5 C) at the very coldest with just a thick wool blanket and some wool/clothing layers? Assuming I'm protected from the wind and elements and I have something separating my body from the cold ground
I understand a sleeping bag system would work much better but I don't want to spend the money if I don't have to
pic rel is the wool blanket i'd be using
