ANy temp rating guess on my planned hammock rig

[tammons]

Asym double layer hammock, made by me with DWR bottom cloth. Similar construction to Risks Z hammock

Speer type pad extender with a regular neoair, and a full length 3/8 CCF pad on top. Wings either single or double CCF. The CCF is dense from bass pro shops. This will go between the fabric layers.

Golite ultra 20 quilt.

Insulated balaclava
Heavy socks
Med wt silk johns

Also will have a golite salsa jacket and probably insulated pants of some sort.

Pillow of some sort. Either stadium balloons or a bag stuffed with cloths.

Galington type taco made out of 2 snapped together driduck ponchos. Will carry a couple of spare garbage bags to stuff with leaves and whatnot for more under insul in case of serious cold weather.

Large UL sil nylon tarp that I can form into a tent type hammock stucture similar to this.

low twenties, high teens perhaps. It seems as though you have more bottom insulation than on top now. With a better quilt, or add a bag you should be able to go close to zero with that bottom insulation.

I have done -11 with a poncho rigged as a garlington taco, 2 garbage bags (justbarely any air in them), two 3/8 in ccf , truck sunshade and a -20down sleeping bag. Was VERY warm. Easily could have gotten to -20. Setup with an 8x10 tarp as a bakers hut to block the 20mph wind gusts off the reservoir.

20-30 degrees.

I think I will build a 2.5 oz climasheild xp overquilt for winter.
I have been planning one for at least 4-5 months and it would make a good summer bag.

I already have some plain .9 oz ripstop and some dwr 1.1 oz ripstop from walmart so I am all set there. Just need $30 worth of climasheild.

That should extend it another 15dF.

Insul clothing a bit more.

I use the Ultra20 as well, but I use it with an underquilt. Some say that the 20deg rating is really exaggerated, but I've had it below freezing with no problems. In my experience, you can get away with lighter top insulation in a hammock if you have really good bottom insulation. So I would say 20 if your pad setup is adequate.

Yes, I guess a bottom down quilt is a priority to keep it warm and light.

Have to build my hammock first though. I am starting that today.
