Tensor Ultralight Insulated Sleeping Pad (2022)

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.

Yeah I have an older Tensor insulated that is 3 inches thick, 4.2 r value, and 20oz, and it also cost around $190 at the time. This Eclipse is just better in every way and doesn't cost more, assuming durability is the same. When my Tensor wears out maybe I'll snag this.

I don’t think anyone else has mentioned this, but if you’re an REI member there are periodic 20% off coupons for full-price items. If you don’t need this right away that might be something to consider. Thermarest also just updated the XTherm and the previous version has been available at a steep discount. I got one for 40% off earlier this month at REI. I think they’re now sold out of them but there’s a chance you could find a deal at another retailer. Have not had a chance to try mine in the field yet but looking forward to it. I have one of the three-season, older versions of the Nemo Tensor and that’s a great pad, too. I also like the Exped Ultra line for backpacking pads.

I have used the Tensor Insulated RW (predecessor of the All Season) and (older generation) X-Lite mummy extensively, and I sleep equally well on both. Therefore, I prefer the X-Lite for it’s lower weight.

I have the NEMO (previous generation) in wide, got on a closeout sale around $90-100 from REI. Works great for me as a 230# side sleeper.
