I would just like to flag up our range of silk liners into the mix if I may?
BTW There are different grades of silk, not all materials as the same, both of weight, texture and performance.
We've sourced ours and I've also added a feature which I've never found on any other liner. We've put a little silver beading around the neck, so that, during the night when you nip out and back, you can find you way back into the flippin' thing!
A silk liner does add warmth, by the very nature of trapping some air, however as mentioned above nowhere near as much as a pile or fleece liner.
We've used different ones for over 20 years, they last very well, and have prevented all kinds of muck getting inside the down bags. They've also travelled around the world with us and prevented many a 'bed bug bite', and allowed us to use the bags as a quilt in warmer climes.
Oh, and as we bought ours last year, the prices are still very keen as Trevor states, silk has gone up last few months.
