The rating is zero. A rating from a reputable company like WB usually means that a lot of people, though not all, can be at least warm enough at the rating.
I disagree .Personally I think go with a sock and smaller tarp, But either way im a cold sleeper so I would definitely be at my limits at 0 degrees.
