I have the Wiggy's liner that uses Lamilite. It's slightly warmer (that I can remember haven't used a service liner in a few years) than the issue liner. I also use it with a solar blanket and a Wiggy's 40 deg bag and was warm down to the 30s.. I definitely think I'll need a true on winter underquilt for the Michigan winters to be sure.. Hope that helps a little.
