I have been using my lovely 3S Incubator (bought in October 2010) for several weeks now. A couple of nights ago, temperature plummeted to around 3°C (all other nights were a lot warmer), and I woke up with lots of cold spots. Now, I am a very cold sleeper, but the underquilt is rated to at least -9°C - plus I had a hot water bottle in my sleeping bag that night. Therefore I figured that I had to be doing something wrong.
After going through a few threads here, I think my quilt wasn't close enough to the hammock. As far as I could feel, there was a 2-finger wide gap between the hammock fabric and the quilt. I assume that this decreased insulation. I now got some shock cord to pull the quilt closer to the hammock, as other members have suggested. I'm waiting for the next cold night to see if this improved things.
However, when looking at the Incubator more closely, I noticed a couple of things that I didn't understand.
1. There doesn't seem to be a head end and a foot end - at least the quilt seems to be the same width at both ends. But on one end, the draw string is made of shock cord, on the other it's a non-elastic cord. Why? Does it make a difference which end is where?
2. One side of my Incubatore has a lot of loops - the other side has none. Which side are the loops supposed to be? And what are they for?
Maybe once I know what these features are for, I will help me to get a better performance of the Incubator?
Thanks for any advice.
