How low can you go

[Sparticus]

I recently picked up a Nest from a member of the forum and I just ordered the 3-season quilt sent from Jacks R Better for when I hang with my son.

Questions is if anyone has tried doubled up Nests. I was thinking that for my solo winter trips I could use both Nests as under-quilts for those very cold nights. I know it is very subjective, but (leaving top insulation out of it, there are a lot of options there) how low do you think the temp could go and still stay warm?

I had a Nest+NS down to about 20 once and was very toasty. I'd guess that with a proper fit you could get to single digits.

If two Nests have 5" of total loft and one Winters Nest has 4" of loft ...seems like two Nests should be good for sub-zero. Unless one gets compressed.

I camped out this past Fri night at a state park here in NE GA and doubled up with both my Nest and No Sniveller as underquilts. It got down to 26 deg with a very slight breeze and I was cold all night. I had base layers and fleece on with head gear too.

I'm a cold sleeper though.

So, this is like the extreme opposite of USMC 2674's post! Now I am amazed that you could be cold at 26 with a Nest PLUS No Sniv under you, assuming no gaps and nothing compressed. That would be roughly 5" loft, about twice the Snugfit. With the 4" loft on my MW4, or with the 2.5"(rated, actually a bit more) loft plus a space blanket on my Pea Pod, I have been able to do ~ 10F and be reasonably warm.

But you are probably like my wife. She would absolutely freeze trying the same thing!

BTW, what did you have on top? Were you cold on your back, top only, or all over?

I was up in the high uintas in Utah last year with the Scouts. I was hanging with the Snugfit. It hailed almost all night the 2nd night of our backpacking trip. The hail was still on the ground in the morning, and the thermometer read 17 below. I was so hot that night (with a 30 degree sleeping bag draped over me) that I ended up not using the sleeping bag. This is in a Hennessy Ultralight Explorer, so the moquito netting keeps a lot of the heat in IMO.

Rest of the nights were in the upper 30's / low 40's and again couldn't use the sleeping bag because of it. I'm thinking about getting a light "sheet" and using it just to have something draped over me but not be too hot.

minus 17F with a 30F rated Snugfit and a 30F bag as quilt, and TOO hot? I know the Snugfit is rated conservatively, but that has to be a new record.

I am a very warm sleeper.

The Snugfit really is rated very conservatively.

If you aren't used to sleeping in a Hennessy, the bugnet combined with an extremely snugly hung tarp really traps in heat well... too well for me during the summer (when I need it most due to bugs). My HH is on its way for a zipper mod before I head to Iraq again so that I can unzip the netting so it doesn't retain heat.

There is no way that 30F is an accurate rating for the snugfit.
I've used it with only a JRB stealth (sewn through) at freezing and been toasty.

Clearly, based on many previous reports. And just based on 2.5" loft with plenty of baffles (good down control) and a very snug fit, it should be good to 20 for a lot of folks. I was always surprised at the 30 rating, seemed like it should be rated warmer than that.

Agree, a HH net ( and even more so, a HH Super Shelter top cover) holds in a good bit of heat and keeps a good bit of wind out. A snug tarp helps to. I am still amazed at MINUS 17 ( is that correct, what you meant when you said "17 below", you meant 17 below ZERO?), and warm enough to not even use the 30*F top quilt, with a 30*F (RATED, I realize it's warmer than that for most folks) Snugfit below.

It just goes to show the vast difference in folks when it comes to cold tolerance. I'm not as cold natured as most folks I know. But still, I'm sure I could not use those items at any where near 17 below zero. 17above, maybe, but not below.

BTW, love those High Uintas! I used to live in Layton, not far from them, and would camp up there often. What time of year was that when you and the scouts were up there? Where did you camp? Beautiful country!

honestly,maybe im a warm sleeper, hanging in NE GA got down to low 30s under a waterfall, with just a '30deg' mummy bag as well as a $10 '40deg' wally-world sleeping bag UQ with base layers/stocking cap and was toasty.
