Used my NeoAir in “Winter” Conditions last week

Nice! I got a GG ThinLight 1/8 for under my Neo Short, and a GG NightLight torso length for on top… just in case. Haven't used the combo yet… so it is good to hear of your results!

I was out on Mt. Hood near Portland,Or last week with my NeoAir shorty for the first time on snow. I use my backpack under my legs. I was a little chilly and didn't put 2+2 together right away. The second night, I thought about the sleeping pad situation and was motivated to try something because of a cold butt. I had some 1/8 inch packing pads along and put a couple of them under the NeoAir. What a difference it made. Like instant heat or so it felt. This was my first time sleeping on snow and what a blast it was. I'm going to extend my backpacking season into the winter and am now looking for a 4 season tent to supplement my Tarptent Rainbow. Probably an Akto or Scarp 1.

Me too.
14F in the Sierras during the snow event 10 days ago.

Neoair short inside a bivy bag on top of 1/8" yellow MEC evazote (full lenght), and my ULA pack under my feet. Sleeping inside a WM ultralite. Very warm. Was on bare ground and not snow however. Slept with this combo for 11 nights on this past trip and never felt cold from the ground. Had several nights below freezing and several at around freezing and was very happy with the combination. The neoair is a very warm pad IMO. I have not slept on it without the evazote yet and likely wont as I suspect it might be a bit succeptible to puncture. In warmer conditions I will liley go for a lighter plain evazote pad but when it gets cold I think it is a good choice for the weight.

Thanks for this guys. I have been wondering how low I will be able to take it to also.

Martin, where were you? We were north of Sonora pass on our way to Tahoe when Dave hurt his back and we had to get out. Lucky us. That night it dumped and where his truck was parked was closed for almost three days waiting for plows. I wondered about a couple of gals that were heading south. I saw their cars at Echo Summit and wondered if they had weathered the storm OK.

A vote to the contrary: I used my NeoAir with a 1/8" (0/32 cm) Gossamer Gear Thinlight last week on an 18*F (-8 C) night and froze! I went to bed at 7:30 pm (what else can you do when it's pitch-dark?) and shivered until midnight. I tried the Thinlight on the bottom vs. on the top of the NeoAir (on top was slightly warmer). I tried putting more air into the NeoAir and it was slightly warmer (I presume the reflecting baffles worked a little better?), but it was too firm to be comfortable and "bucked me off" nearly every time I turned over (which was often). My 20*F (-7 C) WM sleeping bag was fine; the cold was coming from underneath. I was wearing a vapor barrier over my base layer and all my insulting clothing on top, plus balaclava and (for the early part of the night) gloves. My dog kept my feet nice and warm, but I certainly could have used two more dogs! I finally warmed up enough to sleep about midnight. By morning, I was too warm, except for underneath.

I wouldn't try the NeoAir again in those temps without a 3/8" (0.95 cm) or better 1/2" (1.27 cm) CCF pad on top–which of course negates any weight savings. I'm ditching the NeoAir and going back to my POE insulated air pad, which takes me down to 20*F (-7 C) without any addition and at least another 5*F with a torso-length 1/8" Thinlight pad. Even more important, it's FAR more comfortable than the NeoAir and I don't roll off it when turning over. That makes it worth the extra half pound (227 g).

Your Mileage, of course, May Vary–I am most definitely a cold sleeper!

"My dog kept my feet nice and warm, but I certainly could have used two more dogs!"

Love it!

Yeah, I believe you. I have taken my BA IAC to 18 F and was cold and that was with a Mountainsmith Cypher 0 F bag (although that rating is quite a stretch for a side-sleeper in a variable fill bag like that.

Thanks,
