NeoAir All Season SV

Yeah. Large size neo-air all-season for me, but I suspect any large (wide) pad over 3.25” would do. Some gear needs to go under the pad’s head end (upper third) to raise it. Bonus if I can raise the foot end slightly too. Inflatable pillow with a foam layer in it (I use the MEC inflatable). Other gear on the sides to rest stray arms on (partially inflated dry bag with clothing on top so it’s not an icicle at 3 a.m.) Edit: I’ve also got a long tube-like stuffsac that I fill with clothes, as a knee pillow. That combo has worked for me. Your mileage may vary.

Your combined R-value should theoretically work for 29F, so something's off. A few possibilities: Ground temps drop 10-20F below air temp at night, so you were dealing with potentially 10-20F ground temp. The 2.1 R-value pad is pretty low. those budget FeatherStone pads often don't perform to their rated spec. Same with the Paria, decent but not consistent. My guess: you had a thermal bridge happening where the low-R pad was letting cold through in spots. Pads also lose R-value as they compress over time. For future trips, look at the NEMO Tensor (R-4.2) or Therm-a-Rest NeoAir (R-4.8) in the $100 range. Better yet, get one solid R-5+ pad instead of combining lower-rated ones.

R5 (thermarest neoair) was enough for me at 5000+ Himalaya in -17C.

Had slept on the S2S Extreme version current and previous model, the previous version of the Neoair and Xtherm with winglock and Exped Versa 4R. Hands down the S2S is the most comfortable pad then followed by Exped and last place is both Thermarest. Im a side sleeper and the Neoair and Xtherm i can't sleep well which sux considering their low weights. The newer S2S Extreme is close to my Xtherm so i take that instead in the winter. Yes its noisy (new and old, i didnt notice any difference but i dont have the older model to compare), so don't camp near people or tell them to camp far from you. I know someone that puts a cover on their pad but thats extra weight without any benefit for yourself.

When I was younger I got a 3/4 length therma rest sleeping pad for a backpacking trip to save on weight. It worked it was fine for the trip, I'm really short anyway and didn't notice. 12 years later I used it again and let my bf use the full body one because he had never gone real camping before. Oh man, I can sleep through a lot and pretty easily. That was the most uncomfortable I've been in years sleeping on the ground. Get one. You'll regret it.
