The issue, I'm guessing, would be if the zipper is one way ot two way so that I can open the footbox. The other open is a DIY with a surplus liner, which will run about $35 less, but I've read here that the Wiggy's is a bit warmer and may have more dueal functionality without cutting nup or tooo much other work on a surplys liner.
Yeah, the zipper is going to be the big deal either way on this one. If it has a two-way zipper, using it as a pea pod would seem to be (haven't done this, so it's from hearsay) very easy.
If you want to go the PLUQ route, an issue liner should be good down to about 40 or 45 for most folks (I find that it'll get me down to into the high 30s, but I'm a very warm sleeper). The Wiggys version should be good for another 5 to 10 F below that, by all reports.
However, if you decide to use one of the issue liners as a top quilt, you may wish to supplement it with your "around camp" clothes around the torso and shoulder area when temps are expected to be below 40 F. I find that this helps eliminate drafts and keeps my core warmer. Even a lightweight fleece zip hoodie works (this combo--along with mid-weight fleece and nylon base layers, a good hat, and loose socks--has gotten me down to 37 F comfortably; I hope to test it down into the twenties tomorrow night).
I hope that things work out well for you!
