Ultralight Mattress

The Ultralight is certainly lighter, and a comfy pad compared to a lot on the market, but the Flex Air is on par with Thermarest Neoloft and Exped Megamat Ultra, except lighter and less balloon-like compared to the Neoloft.

I’ve got one of their ultra lite pads. It’s the most comfortable pad I’ve used that wasn’t self-inflating. I’m a side sleeper and prefer it over both my nemo quasar and nemo tensor.

I debated these two and picked the Zenbivy UL instead as it rated higher for comfort.

I have that same pad and it is cold. I bought a new zen bivy pad to replace it and will just use the BA in the summer

I have the Vango Aotrom Thermo Platinum XL and it has lasted me for years in really low temps(-6⁰) obviously there's more to a sleep system than the pad to be comfortable in those conditions. I have recently moved to the Zenbivy Ulralight Mattress which has the relatively same R rating but way more comfortable from construction and dimensions.

I had the Vango Aaotrom Thermo Platinum XL for years and slept fine on that as a fidgety sleeper. Had it out at -6⁰C once and it handled it fine with a lightweight foam mat and decent bag. Just upgraded to a Zenbivy Lightweight Matress which is waaay comfier though and slightly higher R rated.

I got the wide/long version of the Zenbivy (being long/wide myself) and it is a great mat in my opinion. It's got good thickness, flextail compatible and I really like the baffle system it has compared to others. I can also atest to it's R rating as I have had it out in negative temps on my tent floor without a footprint and not felt any cold spots.

Holy Exped Batman! Might need to get one eventually, but atm my go-to when weight isn’t a factor is putting an extra thick (~1/2in) yoga mat under my neoair xlite. When weight is a factor I use a regular folding closed-cell foam pad under my clite or Zenbivy ul. It still mostly does the job, but isn’t quite as good.
