Liner and Quilt Combo

Most people who use quilts use them in combination with insulating clothing for optimum weight vs. functionality. Using a quilt with a liner would (and does) eliminate drafts. In fact, if you put a silk liner on the OUTSIDE of a quilt, you can do it even more effectively. The only problem would be that you'd still need the extra clothes if you are to be able to get up in the morning/work around camp at night/etc and be warm. So if you bring the extra clothes, which effectively do the same thing as a liner, then you're going to have the extra weight of the liner to carry. In some seasons/regions, I could see a quilt-liner combo as being ideal, though. For instance in the desert in the warm season, it may stay pretty warm until about midnight, then drop off to the 40s quickly for several hours before warming back up shortly after dawn. Using a light liner for the first part of the night and then pulling the quilt over you when it gets too cold would be an effective strategy, maybe even ideal, if you know that it will be warm enough in the morning and evening that you don't need insulating clothing. A silk liner is only about 4 ounces so it's a bit lighter than a l/s t shirt and long underwear combined.

The main problem with sleeping bag liners that I often hear is that if you're wearing clothing inside of them, things tend to get tangled up and uncomfortable. But if you're the type of person that likes to sleep in minimal clothing, or you just don't roll around at night, it shouldn't be a big deal.
