For comfort alone i could not do that. Some can. Not me. A comfortable place to sleep is THE biggest luxury on the trail. It’s important to be comfortable. I took a neoAir torso length and a torso length GG evazote 1/8 inch to go under it for more warmth, but mainly protection for the neo air and a something to lay or sit on during breaks. It’s really nice to have a foam pad for laying down on during breaks!!! When you don’t want to inflate your air mattress.
It was a nice UL dual pad setup, with my food bag and backpack under my lower legs. I still got a couple holes in my air pad, so having the foam pad helped when i had a slow leak that i had trouble locating for a few days until i had access to a pool of water to put it underwater in to look for the bubbles from the pin hole puncture! I patched it and was good.
I now use the neo air winter / 5.7 r / 4 season full length pad and love it! No punctures, even on some sketchy rocky ridge bivy setups.
I did a gossamer gear evazote 1/8 in pad torso length and a thermarest neoair torso length. It worked well. I had the exazote for rest stop to lay down and it protected my neoair from punctures and added some warmth
About 12oz between the two
I don’t do extended distances anymore so I would probably keep my x-gold and Nemo inflatable for comfort. I mean I do after all want to be able to get up in the morning and hike. LOL
I bought an old version of a Thermarest Neoair XTherm and while I am not too bothered by the sound it makes, I find it somewhat uncomfortable. I’m not sure if there’s a slow leak? Or maybe it deflates a bit due to the drop in temps overnight.
It’s more to do with the baffles and “falling off” the sides. I’m a big guy and it’s a large (mummy).
Sea2Summit seem to be clearing out their pads at the moment so I got a deal on a Ultralight Insulated pad. I’ve only slept on it a couple times but find it much more comfortable. However the R-Value is only 3.1
I mostly camp in shoulder seasons in Canada so it should be fine. I will keep the Xtherm for any future winter camping.
The Ether Light insulated is R 4.1, and the Pro version is over 7. So maybe worth checking those out.
The teal-green / purple Therm-a-Rest that was sold from the late-1980s into the early-1990s was the “Ultralite” series (sometimes just called the “Therm-a-Rest Ultralite 3-Season”).
• Nominal thickness: 1 in / 2.5 cm
• R-value printed in the catalogs of the day: ≈ 3.0–3.1
If you were to test the same pad today with the current ASTM F3340-18 protocol, the value would come out a little lower—about 2.4 – 2.6—because the modern test is stricter and reports lower numbers for the same amount of insulation.
EN1355 Sleeping bag rating are determined using an ~R5 pad and that is a minimum R-Value for winter camping to achieve the warmth rating of your sleeping bag.
The latest Thermarest XTherm NXT/NXT MAX models boast an R-value of 7.3, providing excellent warmth, while older models (like the original XTherm) had an R-Value of 6.9.
The Therm-a-Rest LuxuryMap sleeping pad (mentioned below) has an R-value of 6.0.
also upgraded to the tensor all season from the old version of the thermarest xtherm. Side sleeping is so much more comfortable now, its not even close.
