This year, I am determined to continue working in my hammock through the winter, including the cold winter mornings (cold by LA standards, e.g.6'C).
I've got *TWO* electric heated slankets: a battery powered one that has most of its elements along my back, and a mains-cabled one with foot-pouches whose elements run down its front.
I'm wearing my EFF staff beanie and a pair of thin, warm "typing" gloves advertised for writers, and I've asked for new slippers for Xmas.
@pluralistic You may want to look into getting an underquilt. Putting the insulating material outside of the hammock means it doesn't get compressed by you laying on top of it, so it's much more effective than having insulating material between you and the hammock.
@jozeldenrust Excellent suggestion, though for now I'm doing OK - and I'm trying to minimize the things that have to remain stable in the hammock when I get up and then get back into it (I get into it in pitch dark, so it all has to be assemblable by feel alone).
@pluralistic
In my experience, it's much easier to get an underquilt positioned correctly than it is to get blankets inside the hammock to stay where you want them.
The biggest drawbacks are that an underquilt is pretty much useless in any other context, and they're pretty expensive, though in recent years I've seen more midpriced options.
