Temp started at 20.3 C and got down to 14.1 C.
Initially I had the UQ pulled right up the head end of the hammock to vent right out.
I ended up pulling it down proper after about an hour and clinching each end up a bit to sort of seal but wasn't very tight and would have had a few air gaps. Also I had the suspension just as it came from HG and the quilt was probably 2" of my butt under the hammock.
No cold spots and the best bit was that I was completely comfy all night and only had boxer shorts and no other clothes.
Also I had a 3 season burrow with the snaps done up but the bottom cord open fully.
I figured I'd not use the burrow but as with any of this great warm down gear it covers a fantastic temp range and breaths well in warmer weather too.
Couldn't be happier.
