Now that I have paired down my wild camping kit weight wise, the idea of silk pj's in my Akto sound rather inviting.

It sounds inviting to me too Dawn!

Down boy!

I made a bivvy bag from a Tyvek work suit. I used an XXL suit.  Chopped off the arms first. Cut the legs open on the inside leg and joined them together to create the 'bag'. I used a piece of the arm material to create a foot plug for the bag. As it was a test bag, i just used duct tape to join everything together. It worked fine as a water-resistant bivvy bag for under a tarp.

Trevor, I've got a Pertex liner I use for if I anticipate being really filthy for some reason.  It's significantly bulkier than my fine silk one (both are Rab), at least twice the size packed.  There's roughly zip effect on temperature AFAICT.

As for the tangling thing... I used to hate YHA sheeties because of that and anticipated a similar problem with a bag liner, but for some reason it just doesn't happen to me, even though I thrash around enough in the night to turn my sleeping bag completely upside down moderately often.  <shrug>

Pete.
