Space blanket and full length 20 deg F UQ
I was wondering if this would be a good idea to try or not. I have a BBO for my WBBB and a Leighlo FLUQ (20 Deg F ) and a -20 deg C sleeping bag. i was thinking to add a space blanket between the hammock and the underquilt for suplimental warmth.
Just wondering if this would be worth trying or will it lead to condensation issues?
Yes, do try this at home.
I 'spect that whether it works for you will depend on how much you perspire, how much your hammock fabric wicks moisture away, and how much air-draft there is between the 3 layers.
Note that if a non-permeable foam pad works between two hammock layers for people, this may work for you. Whether it improves the UQ's performance varies in the same way that vapor-barrier insulation does.
