I imagine it's tp ensure a consistent air gap.
That's the challenge: to come up with something that approaches ccf in performance, without giving up the comfort that makes me a hanger in the first place. I love the way my hammocks wrap around and cradle me...the temptation is to call it womb-like, but I cannot tell a lie: I don't remember that far back.
It may not be doable, but I'm going to play with it.
I did experiments with the Insultex poncho as an UQ shortly after TeeDee flagged that thing as interesting. As others have rediscovered, the IX is highly compressable, and I got cold spots wherever I had compression points.
What might work for Insultex in an UQ is to stick something between it and the hammock body that better adapts to the
various contours, maybe that's down with the IX being on the outside, maybe its synthethic. Probably need to have the piece next to the hammock be a vapor barrier. I've not been tracking the Insultex chatter so all of this has likely been said and maybe done before. I lost my interest in it when it didn't pan out as a dual-use poncho/UQ.

MrPrez had a similar report, that it performed poorly underneath, with cold spots.
Your description makes sense, though, when you figure that the best use of it that I've found was on the outside of my PeaPod. No compression of the IX, but a tight fit.
I agree Grizz. By playing around with material inside the hammock layers, it just confirmed what Mac experimented with. it will need to be either on top or under the hammock with airspace for it to work as intended. I noticed that Duluth Trading Co. has a new insultex jacket out- it uses a thin piece of 80 gram poly insulation next to the IX and provides loft in between layers. Fleece might work if it has alot of air space- like berber fleece instead of microfleece.
So...IX between the hammock and the hammocker is a bad idea, then?
