Insulated Air Core Ultra

Might be an issue specific to the pad or your back. We can be pretty particular when it comes to sleep, and it can take a few tries to really dial it in. I have a big Agnes air core pad. I don't think it's warm enough for winter camping but I've been comfortable laying on my back on it. I do usually side sleep, but I wake up on my back often and sometimes just lay on it to relax at the end of the day.

This is the biggest drawback I had with the equivalent burnt orange Big Agnes Air Core Insulated, but BA replaced it at no cost within a week ^((although now it's the Divide Insulated Pad in a quite awful yellow and slightly lower r-Value...))

You must be a warm sleeper. I would classify myself as an average-to-cold sleeper, and I'd absolutely freeze on an R2 CCF at 32F. Forget about going lower. The first time I ever slept comfortably at freezing temperatures was the first time that I used an insulated inflatable sleeping pad (Big Agnes Insulated Air Core Ultra, R4). I was 38 at the time. The previous 27 years of my camping experience, I slept on CCF and froze my ass off whenever the temps were below 50F.

One issue I have with the Klymit pad is that it’s pretty thin, only a couple inches when inflated. That means it has to be full of air - which makes it very firm - or at least that’s what mine feels like. I use a Big Agnes insulated air core long version for my backpacking trips and letting just a bit of air out makes it feel softer.

At Philmont, even in summer, you’re going to be dealing with elevation, cold ground and nights that can dip into the 30s. In those conditions, an R-value around 4.0 or higher is a safe target if you want consistent and comfortable sleep yk. A tent doesn’t provide insulation on its own so your pad is doing almost all the work underneath you. That’s why an insulated air pad makes a lot more sense than an uninsulated one for this use case…I’d recommend: - the Therm-a-Rest NeoAir XTherm (regular or MAX) OR - the Big Agnes Insulated Air Core Ultra If you’re on a tighter budget, the REI Flash Insulated would probably be better.

Klymit is durable. It's like 70D. But my dog has a big Agnes aircore insulated and it's holding up. Probably 40D outer I've got a Rab hypersphere 7.5 down filled and it's 20D outer. Also holding up but it only have a few trips, so time will tell. Klymit is heavy, not warm but durable. It's my summer pad.

I have a Big Agnes Air Core pad. Coupled with a Sea to Summit pillow it packs down to the size of a large beer can and is more comfortable than most hotel beds. I have a little pump (believe it’s called Little Giant) that inflates and deflates it for me easily, and in a pinch can be really helpful for starting fires!
