A Katabatic quilt and the Rei Flash 55 would be next to pick up. You won’t need the switchback much, the Neoloft is plenty warm and durable.
You mean backpacking? The Megamat ultra is my favorite comfort oriented pad that you can use backpacking but it’s pretty bulky, but for shorter distances or more base camp oriented backpacking trips it’s fine. The Thermarest Neoloft packs smaller while still being very comfortable so that’s a nice compromise. If you are pushing miles, the Rapide SL, Nemo Eclipse, Exped Ultra 6.5 are really good.
This is what I use!! Definitely worth the extra weight and little bit of time it takes to inflate. I sleep like I'm in my own bed
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.
Probably late 80's or early '90's. Earlier iteration had a metal valve although that could've been replaced. Nice find. Spent many night deleting on one but have upgraded to a Neoloft, which I must say cost me a little more than $3.
Get something with 4 inchs of thickness. Us big guys need that level or near to it of thickness. Nemo Quasar is close, same with Big Agnes Campmeister. I have the Thermarest neoloft and love it. I'm also a big guy. Thermarest and definitely the Campmeister are good for those temps.
Megamat Ultra and the Thermarest Neoloft are comparables. Def not ultralight but I use the Thermarest on backpacking trips, not thru-hikes, and love it. I'm a big guy and the Thermarest is comparable to my MondoKing and Exped MegaMat Duo. The Ultra will work well for you.
