I'm waiting for an RBH sleeping bag vapor barrier liner to arrive and am curious if others have used it (or a MYOG version). I use a quilt and bivy combination and was thinking of hoisting the vbl to my armpits and still using a down parka over the VBL and under the quilt for extra insulation. How useful will the VBL be for keeping moisture from escaping and affecting my down quilt's loft?

I have been working with Joe at Zpacks and will soon have available the TrailLite Designs cuben "CloudLiner", this is a VBL that can be used in quilt or bag mode and will be UL light.

Sounds great. I'd be interested in a liner that was fashioned for a quilt. After all, I didn't get into quilts just to box myself into a bag liner!

any updates on this new product? didnt see it at zpacks or traillite

It used to be on the zPacks site, but it's not any longer. Don't know why. I have one fashioned for a quilt, I've taken it on a couple of trips but haven't had to use it yet.

I use the Heatsheets SOL emergency bivy as a VBL liner.
Cheap, and it works.

I take ultralight wind/rain gear and figure that in a pinch I'd use it as a VBL. My Mountain Hardware Phantom 45 has been so surprisingly warm in a bivy that I have not resorted to a VBL even when it dropped down to the mid teens F.

@douglas - what is the weight of your VBL? is it from 0.51osy cuben? when you say "for a quilt" i assume you mean shorter than for a full bag?

@tom - i had thought of that...but my understanding was that cuben has better weight/strength performance...
