Just to add a bit of context here: Some of the old model pads you can find have a Klymit R-value rating, compared to the industry standard ASTM. [Discussion here](https://www.reddit.com/r/Ultralight/comments/euwcv1/updated_klymit_rvalues_with_the_new_astm_standard/). My v1 insulated static V, which Klymit still sells and advertises as 4.4 R value, has an ASTM R value of 1.9. They do advertise their _new_ versions of those pads with ASTM R values.
For budget 4 season AND ATSM tested, Justin Outdoors reviewed the Hikenture sleeping pad: HIKENTURE Sleeping Pad, 6.2 R-Value Insulated Camping Mat with Pump Sack, Ultralight Inflatable Sleeping Mat, Portable Self Inflating Sleeping Pad for Camping Backpacking Hiking(186L x 64W) https://a.co/d/cEha9rX I have used this pad in the winter months in Northwestern Ontario, I definitely prefer it over the non-ATSM tested Klymit pads (though they are slowly seeing an ATSM rating now). Slept great @ -20C. For 3 season use, Klymit isn't _bad_. My kid sleeps on it when she comes out for a Thanksgiving campout in October. We use this paired with a CCF pad, but in summer, no CCF pad needed.

My Klymit Static V wide was a game changer for me. I had quit camping. (.side sleeper, hate cold ground) Half inflated it’s warm, holds me in place, and packs small.
We have a klymit double insulated ultra- light static v, which may have only been offered in mass drop. I think the static v is rather divisive, but it has worked really well for us.
I love my Klymit Static V insulated
I have a Klymit Static V Insulated (4.4 r value) I used on the GDMBR in 2023. I somehow managed to poke a hole through both sides including the tyvek ground cover and tent. Shit happens when you sleep on the ground. I patched it back up with the included patches and it's been fine. I consider these things to be consumable and assume I'll have to replace for whatever reason. They're just glorified pool floats. Also you use your breath to inflate them and I suspect they get pretty icky eventually. I try to air mine out whenever possible in the sun hoping that keeps the air chamber somewhat disinfected. I bought mine discounted at Sierra. Not showing online at the moment but might be in stores or this one looks like it's the same thing under a different sister brand (same copy on tag). I need to get one for wifey and I'll probably get this one.

+1 for mec reactor (my solo, 5 years old) or klymit static insulated (double, for doubling, 3 years old) and aquaseal uv for field repairs and aquaseal seam grip for reinforcing the repair at home
I would maybe start with better insulation below, I know that pad says r4.4 which should be good in that range but klymit pads are usually not that warm partially for their pattern.
