I got a new 20* 3/4 length UQ and decided to test it out in my backyard in combination with a double layer Reflectix pad. The first night it was in the lower 60's during the day and dropped down to the mid-40's during the night. I used an Ozark Trail down 32* sleeping bag as a TQ. Everything worked great - stayed warm and had a good night's sleep. My SF tarp was dry on the inside and a little bit wet from the dew on the outside.
The next day was in the upper 70's and dropped down to freezing creating a heavy dew. Around 4am I started getting cold and woke up with CBS. My SF tarp had droplets of water on the outside and heavy dew condensation on the inside. The TQ was still dry and sufficiently warm.
I thought maybe I'd rolled over or something and dislodged the UQ. When I checked, it was still in its proper position. However, it also had a lot of condensation on the bottom from the heavy dew. I surmise that the dew reduced the insulation quality of the down UQ, a known issue w/down.
The only solution I can think of is to use my Spindrift to prevent the condensation on my UQ. However, that means I'd have to pretty much use the Spindrift every time I camp since these heavy dews are hard to predict. Otherwise, I’d have to disassemble my hammock and configure it with the Spindrift in middle of the night under a soaking wet tarp.
Or, I can invest in heavier, less compact synthetic insulation, which I really would prefer not to do.
I am also wondering if I’m going to get a bunch of condensation inside my Spindrift if I vent it by leaving the zipper partially open. Has anyone had experience with Spindrifts in heavy dew like this?
Any other ideas for solving this problem?
