so I'm going to chime in. :) Regardless of the thermal gradient
across your bladder, it's still part of your body, and you're expending
energy to keep *all* your mass warm. Including any urine in your body.
Of course, the amount of urine in most people compared to their body
mass is very small, so the energy expended to keep that particular part
warm is very small.
Along this line of thinking, you should get rid of anything else extra
too. Have an evening constitutional, get your wisdom teeth pulled,
have an appendectomy, and haul out that gall bladder. You don't really
need them, and think how much warmer the rest of you will be.

First, it lets you wear the liner while you're wearing the
poncho. Second, it converts the liner into a zippered
I've never tried to use the poncho as a sleeping bag. I use
it only in a hammock, and have given up putting anything
between me and the hammock that can be compressed.
It's certainly large enough to make a bag. It has tieout
straps all around the edges, so in a pinch you could tie it
into a bag and sleep with the open seam down. At least that
would let you try it out as a bag.
