AFLM,
From the Manufacturers Web Site (
http://wiggys.com/category.cfm?Category=41) for the civilian sale of the two bags together, no Bivi (Wiggy's states that it does not increase the temp rating). It may be an improved version of the mil spec one, but I suspect that these might be overruns from a govt contract, even though some of the military is changing to a center zipper version:

This is the same bag, except for color, that I have and I can tell you that the temp rating on the bags independently (I have never had them in -40 yet so I don't know about the combo) are cozy for me. I sleep warm in most bags though.
Mark,
This sale might be a good possibility. It is only the liner/3 season bag, looks like they made too many for the govt. Sometimes you can get the pair (overbag rated to 35F and Superlite rated to 0F) new surplus or on ebay for only a little more. Gives you a summer bag, a fall/spring bag and a winter bag all in one.
Ebay has some used surplus ones for $27.95, Buy it Now from a well rated source. I don't know the vintage but they look like the ones from the web site AFLM quoted above. Might not be quite the same as the ones now at Wiggy's.
Respectfully,
Jerry
