Does this Bivy or any Bivy add to the temp rating of your sleeping bag? For instance, Does a 20 degree bag feel like a 10 degree bag stuffed in this type of bivy sack?
Reason I ask is that I'm trying to decide whether I want synthetic or down. From everything I read down should not get wet and this would alleviate that problem.
