I have a synth rectagular 35* bag from my car camping days that I successfully used by it's self into the upper 40s. No CBS, and was actually a bit too warm. Clothing was a wicking synth shirt and running shorts, had to take my socks off in the middle of the night because my feet were roasting. Had thrown the pad out of the hammock earlier in the night as it was making things uncomfortable for me. I only use this bag in the backyard as it weights more than any other peice of gear I own (72 oz ) but it worked successfully.
P.S. I'm a freaking furnace when I sleep also. I've woken up sweating in a 50* room with sheets thrown off me, a fan blowing and me in my skivies.

2014 Smoked Butt Hang Planning Thread | Sign up Sheet
it's winter here in Australia at the moment and next weekend I'm off for a two day, 60km (37 miles) hike.
the weather is expected to go as low as 4c (39f) and I've got a synthetic sleeping bag modded to be my UQ rated for +10c (50f) and a synthetic sleeping bag that opens flat and has a bit of a footbox going on rated for +5c (41f). Both bags weigh just a smidge over 1kg each (~2.2 pounds each).
I'm hoping I've chosen wisely, and that I don't get too much of a cold butt during the night! Worse comes to worse, I'll zip up the TQ and get snug as a bug in a rug in the hammock
Will repost after the hike and let you know how I get along (unless I freeze to death - it's been nice knowing you all!)
Cheers,
Jason.
All in all and I'm loving every rise and fall the sun will make and I will take breath to be sure of this
Count me in as another very interested party to this discussion.
I just got my first hammock and I'm already mulling over my options for insulation. I have an old REI synthetic bag that was originally rated down to 0 degrees, but in real world testing it's more like mid-20s when also using a good pad and proper sleep wear. The thing doesn't compress much at all - huge annoyance most of the time, but maybe a positive for use in hammock camping?
I'm wondering how I'll fare using this synthetic bag plus a ridgerest pad. I'm also wondering if I'll be able to do the gymnastics required to use all of that inside my hammock.
I also recall people using the Pound Hawg approved Military Modular Sleep System. Using the 2 bags together in the hammock alone achieved good results to well below freezing. If I recall, these 2 bags weight close to 9 pounds and don't compress that much so that is likely the reason why they seem to provide good insulation without a pad or underquilt.
However the main issue with sleeping bags is the wrestling match it takes to get into the bag and into the hammock in a comfortable position. Then repeat said match when you have to get up to water the trees at some point during the night.

I remember 4 years ago i was on a mission to find the cheapest way to hang and stay warm.... i remember trying to zip myself into a Synth sleeping bag
if i remember i was good down to around the mid 50's or so....
i think i tried just about everything out there befor i broke down and got a quilt
yeah i can say with a GOOD synth sleeping bag you could get into the 50's
but for the weight and bulk you might not be happy
a pad would be better
It puts the Underquilt on it's hammock ... It does this whenever it gets cold

Yeah, totally. That may be why I was comfy in a 15 degree synth bag in the low 30s. It's heavy and does not compress easily. Also, I have a JRB bridge which has a wide pocket for a pad that hangs just a little loose. That little airspace as thin as it is was probably adding a little bit of a windbreak.
most ive done is got to 44 degrees in a 50 degree bag. 1st night I used a pad and was warm. 2nd night fell asleep without pad and woke up frozen alive. stuffed all my clothes in my sleeping bag and did what I could but my body wouldnt let me fall back asleep . but I know I sleep in the low 50's with a 50 degree bag as a topquilt and just the hennessy underpad without undercover

Randy : yea but just remember yer roots and where ya come from....you got Hennessy in yer blood son......
Were you even inside that 50* bag at 44*, or just using it as a TQ? If a TQ, yep, 44 is really asking for it!
But what I need right now is a sort of Anti-sleeping bag. Something that will actually subtract about 20 or 30 or 40*F from the air temp, and dry the air out while it is at it!
Seems to me that this one is settled just by experience: Sleeping in a synthetic bag with no pad into the upper 40's and my back was just slightly cool. Got out to pee and I noticed that my back must have been warmed by the bag, as it got colder while I was out. The bag must have been warming me some in the back, otherwise I wouldn't have been able to sleep at that temperature. Maybe it provided 10 degrees of warmth? That's all you may be shooting for if you have a summer quilt already. Trial and error at this point I think.
