    Space Blanket as weather guard.

    Has anyone used a spaceblanket on the outside of the UQ in winter? I was wondering if it would extend the use of a 3 season UQ a bit further into the winter months.

    If you use one, place it on the *inside* of the quilt, not the outside...it acts as a vapor barrier.

    Here's a good thread to read up about using vapor barriers.

    Thanks AS,
    That was very insightful. Can't wait to try it out this fall/winter.

    They help some, and they do help keep your down drier. That being said, don't expect too much of a boost. I'd say somewhere between 5 and ten degrees.

    Further on the space blanket placement: Any benefits with a double-layer hammock like the Blackbird with the blanket placed between the sil-nylon layers?

    A space blanket will reduce radiant heat loss more than sil, but you're really not losing that much heat due to radiant heat loss underneath. That being said, it will offer more warmth than not using it.

    AS, I'm confused. He was asking about an UQ. Aren't you talking about a top quilt? I would think you'd want the wind break outside (underneath) an UQ. Am I muddled?

    I was indeed talking about an UQ.

    If you have a vapor barrier on the outside of an UQ, but not one on the inside....then your body moisture through radiant heat will enter the UQ and not be able to escape because it is stopped by that vapor barrier. Do that long enough, and you'll wet the insulation, thus reducing it's efficiency.

    The rule of thumb with VB's is that if you use one, it goes nearest your body with regards to the insulation. If you use two, then you can place the second one on the outside, as a wind break.

    I used a PU coated poncho as a weather shield on the outside of the UQ when it became obvious the temps would drop a LOT, to keep a little bit of a breeze from leaking through - there was ice on the UQ shell.

    Was almost - but not quite - cold in the hammock. No rain, no dew - the ice was my insensible perspiration hitting the barrier and freezing on the quilt. There was just a little air gap between UQ and poncho.

    That's a perfect illustration of the issue.
