I find woolen blankets much easier for hammock sleeping than sleeping bags. No wriggleing just jump in wrap yourself up like a samosa. The blankets I use are cream WW2 or pre-war marino wool. I was given a pile of about 10 blankets from the parents in law plus a wool sleeping bag. Some of them have had the ultimate kit test of the MIL sleeping wrapped up with her sisters outside in a park in winter during the blitz. I feel the cold, two blankets is normally fine in most weather but I have had to use a foil sheet one night in winter.
