Lightweight "Jungle" Sleeping Bag - How Low Will It Go?

#1
How low will one of these bags be comfortable at with the liner and / or a US poncho liner?

I'm guessing about +5 - 0 would be ballpark?

Thanks,

In our experience it really is person dependant....

For me, I used one a week ago in a building and I was cold. Other people will be fine.

Generally... Jungle bag is ok for summer in UK. Other wise I'd go for something that offers a little more techical advantage i.e. mummy shaped etc. (shameless pug, we are doing an "Arrse Offer" on the modular U.S. system at the mo, dirt cheap)

foxs, that's what I had on the Pentlands last week, poncho liner and a snugpack thermal liner, was comfortable but could have been warmer, this was all inside a bivvi bag as well, I would have preffered my softie bag though.
 
#4
also a trend for people to use the issue "bivy suit" with jungle bag.... (not saying its a good idea)

I guess it also depends on your role?

In a rush once i accidently grabbed my Jungle Bag instead of my Softie 9 and spent the next week gibbering my balls off, even with warm kit and two bivvy bags! If you don't mind being a bit cold then by all means try it, but i'd fork out for a Softie 9 Hawk or similiar if you thinks it's gonna get a bit chilly.

I've got the big "Arctic" type bouncing bomb for winter & a "Jungle" bag for summer / autumn & indoor use (crashing at friends' places etc). I really wondered about that twilight zone where the big one's still a bit big but the little one may be losing its effectiveness a bit.

Of course as others have said, each person reacts differently.

TBH I'd invest in one bag that does it all but with a reduced pack size...

Yes, don't have it in the stuff sack, it should really go inside the bivvy bag then it can be 'moulded' to fit the bergan.

Shove it in the bivi bag shove it at bottom of Bergen everything else on top should squash it down enough.If everything else is in a dry bag not really an admin nightmare.
Jungle bag not really much use outside of summer if you feel the cold.Though saw someone happily snoring away in one in december in hankley common though he does like his pies :).

i used one of them on an ex at garelochead in april, had a bivi bag and a poncho liner too. still too bloody cold. sure it saved a bit of space in my bergan but i wish i had taken my old doss bag instead. think its just suited for summer use really.

The good old layer principle also works well with doss bags.

There used to be, back in the Stone Age, an issue inner sleeping bag (arctic only I think) with a hood made out of KF shirt type material, which made things really comfy. Wish I'd kept mine.

In da jungle, I always use a cotton liner bag with hood, as well as a jungle bag - if only to soak up the sweat to stop it from making the bag cold later on. I also carried a really light-weight pure wool pully as part of my dry night kit.

On one very cold high-altitude mountaineering exped, I found a flannette hooded sack inner really good too. So I've got a selection of inner bags - for all seasons. They don't weight very much, and have multiple uses.

You may get a lot of stick for it - I certainly did - but on H9 I took a small hot water bottle. Nice little heat source kept me toasty warm all night while all around me shivered.

MY greatest discovery - the Army Mountaineering Soc boss Ivor Hellberg told me about it - was the sleeping-bag pee bottle - at least 2 litres with (of course) an enormously wide mouth. No more getting up in the middle of the night freezing, and a nice warm bottle for at least an hour to keep the feet warm. Just don't get it mixed up with the other water bottles.

Any tips on carrying the issue bouncing bomb in an issue Bergan ? and still have room for kit in the Bergan ?
I've not used the bouncing bomb since it was first chucked at me. Too big and bulky and luckily enough too warm for me in all the UK training I've done.

I've got an intermediate softie bag and carry a decent liner and/or softie jkt & trs as weather demands.

Then again, our grown-ups aren't that bothered what we use as long as it's not got cartoon characters on it.

See if you can get a better compression bag and stick it in a quality canoe bag rather than rely on wrapping it in the bivvy bag alone.

Just got back from spending 3 nights on Hankley Common (that's the extent of our annual sqn ftx) and with overnight temps down to about -3 I wouldn't have been without the bouncing bomb and bivvi bag as well as a roll mat/inflatable sleeping mat. With the doss bag and bivvi bag stuffed in the bottom of my bergan I still had room in the top for all my warm kit, deflated sleeping mat, water proofs and an empty patrol sack.

One guy on this ex went on last years equivalent with a jungle bag hoping to save space, with the temps and weather conditions the same he spent the first night sleeping in all his warm kit and had a bouncing bomb bought out to him on day 2. This year he went straight for the bouncing bomb and just made everything else fit around it.

Like I said, horses for courses. I can get away with it but others dither even in the bomb.
You need to try it out I 'spose

First week on the prairie in Canada. 35 degrees during the day, though "how cold can it be at night!". Froze my ass off in jungle bag, never strayed from the bouncing bomb again.

I did Offa's Dyke (south to north Wales) over ten days in late August, mostly camping in a tent, and the jungle bag wasn't warm enough. I ended up wearing long johns and trousers, and covering myself with a softie, and while this was warm enough, it wasn't physically comfortable. I was reasonably well-fed and had hot tea, but due to my small size (5'4") I suffer from the cold generally. I clocked 36degC body temp at the time, admittedly, so something else may have been wrong. If you are generally at the 'vulnerable-to-cold' range, then you want something warmer.
