Hammock underquilts query Make do with

So I am finally going to have a go at a simple hammock.
From my readings and conversations with hangers I know about the cold weather problems and the need to below hammock insulations.As almost always I am on a pretty tight budget and need to utilise items I already have.
Part of my stash of gear are my summer sleeping bags, a S2S TR1in the XL size and TR2 in a Large; and I'm wondering if anybody here who hangs has used either as an underquilt and if so did either of them need to be modified in any way?
Otherwise would; in the forums opinion; would either of them work well enough without modifications except for a loop to hold some sort of attachment device to hold them in place?
Assuming a reasonable clearance between the hammock fabric and the S2S would I gain much dead air insulation to allow use below the EN ratings?
As they have compatible zippers I'm guessing that if it was really cold I could use both in conjunction but I think if it was that cold I'd be more comfortable in a great big tent with a wood stove and a cot

I've put on a bit of belly fat lately and I'm currently pushing 120 kilos so I have some concerns about the strength of the finished article.

Is it worthwhile adding in a small section of additional fabric in the centre third? I have some small pieces of cheap ripstop here including one off-cut about a metre and a half long.

If I did this I was thinking that if I finished the cut edges and only sewed in along the selvage would that;

A: Add to the overall strength?

B: Be a good way to secure a thin CCF pad if I thought it was needed?

I don't know how people can handle hammocks for sleeping in. I am a cyclotourist, and although I can carry a bit of weight on my bike, especially having my dog along, I prefer, the tent. I cannot see how a hammock can be hung in the desert, or for that matter in mallee scrub. I suppose they are good for the big scrub or rainforests. I can't see how you would be warm in winter though. I watch a fair few camping vlogs on youtube, and even campers with the correct winter hammock set ups, they complain that at 0 C down to -8 C, they just don't seem to be able to keep warm. If you are going to use the set up, that you have mentioned, I would stick to camping in warmer weather.

These days there are options for hanging in treeless terrain, sandy deserts & beaches etc etc.

You can hang @ a icy -25°c through to a tropical 35°c...just have to choose the appropriate gear, if your getting cold during the night it's normally user error. :wink:

I have modified a sleeping bag to use a top quilt which I really like & still use, but not as Under Quilt.

Probably the easiest idea.....I am assuming gathered end hammock here.

Double layer (to cover your weight) sewn in diagonal sleeve(stops the insulated mat from moving around) A Under Quilt does give you a wider sweet (warm) spot, so you can move around without hanging a body part over the edge of the mat, thus missing out on the cold butt/arm/leg syndrome. :D

Material length & width make a difference....

Basic rectangular gathered end hammock Under Quilt... don't worry about the slit down the middle, that's for a bottom entry Hennessy.

You can taper the ends if you wish...

Hoop & cinch buckle in each corner. (Hang from hoops & close ends using cinch buckles to hug hammock shape).
2x extra hoops or velcro/Omni tape on each side along the longest length.(Again to hug hammock shape for warmth or to loosen off to cool down).

Your decision if your sleeping bags are suitable....

I just visited his website and found some good stuff.
Yes to being a simple gathered end although I did think about a hybrid and had thought about a hybrid in the past.
Good idea about sewing in a small pouch to put stuff in, headlamp/reading glasses/water bottle / pee bottle etc. maybe 2 and keep the pee bottle separate.
This is heavier fabric than I originally thought, the 4.5m length I cut from the roll weighs 550grams. Somebody over at the Ski forum has suggested looking at a Peapod if I'm going to any real cold weather hanging.

OK so looking at the attached picture I can see that the hammock needs matching places for the tabs to go through. I may have some mitten hooks here.
Looks like either of my summer sleeping bags would work as underquilts being the largest size Travellers S2S offered at the time.

Yes to matching tabs on the hammock.
Pouches either side are really handy or hang a pouch off your structural ridgeline above your head.

If I'm expecting temps below -10°c I just add another Under Quilt. Doubling the thickness, more insulation, more warmth. Doesn't have to be full length, it can be 3/4 or even half length covering your torso only. Much the same as layering with clothes.

Have fun with your new project, Moondog. 8)

Here’s a video shot of hammocking in seriously cold weather by one of the hammocking gurus - Shug Emery:

Note that he’s a professional clown in his day job so he has a particular “style” that you may or may not like.

Re locations, I have slung my hammock in places where you could not put a tent. Examples are across small streams, on 20 degree slopes and above sharp rocks.
And, of course, there are places where you can’t hang a hammock without artificial aids.
If I know ahead of time that there won’t be anything to hang from (eg Brinkley Bluff on the Larapinta), I just take a sleeping mat and “go to ground”.
