I have one of these because I'm a side sleeper and it's insulated too. It's comfortable to sleep on, but you need a good tent footprint to stop punctures. CCF would work well.  https://klymit.com/collections/insulated-sleeping-pads/products/insulated-ultralite-sl-sleeping-pad There are reviews of them on YouTube.

Klymit is known to completely bullshit their R-value ratings. They had an insulated pad rated at 4.4 that they later (had to?) revise to 1.9. I personally wouldn't trust them. Big Agnes pads are leagues better and have excellent customer service if you have a failure. They replaced my broken pad no questions asked, no shipping costs.

That's not to say they aren't a good affordable option if you're camping in hot weather, but just stay clear of the insulated claims.

r/canoecampingNeed new sleeping pad for canoe trips (sidesleeper) suggestions?

Lots of good suggestions in this thread, but many are on the pricier side for air mattresses. If you need a more budget option, consider the Klymit Static V, it's quite a bit cheaper, and for summer use I find it just fine for comfort as a side sleeper. Just stay away from their insulated pad.

There's nothing wrong with the pad itself, but Klymit's claims are what's off. Their stated vs ASTM measured R value was way off when it first came out, and I wouldn't trust it (as a Canadian, your climate may differ) as a 4 season pad.

Any insulated Klymit that’s not a crazy color. Used and abused Static V going on its 9th year!

I was also going to recommend Klymit. Why avoid the insulated version? I've used one for nearly 10 years and have always been happy with it.

Ahh fair enough, thanks for clarifying. I'm also Canadian and have used it winter camping to about - 10 C but in conjunction with a Z lite. Shoulder seasons I've used it on its own to about zero and it's better than non insulated but I don't know enough to say it lives up to the claimed R value.

r/WildernessBackpackingIs the best sleeping pad subjective? Maybe seeking recommendations.

Yes it's a matter of seeing what works for you. Personally - I am a side and stomach sleeper. Mummy type bags and narrow tiny pads suck. I used to use a Nemo bag with a sleeve to receive a Klymit V. This worked ok, but not great at all. I finally got fed up and too the extra weight. I now use a Big Agnes Rapide double wide and a Kelty Galactic down rectangular bag. Went on a trip last week and it was the best camping sleep I ever had.

My ass is always hitting the ground with the Klymit V. I bought one on their clearance sale and I wouldn’t even use it for summer.

r/HammocksAny good hammock, sleeping pads like the Klymit hammock V.
5 months ago

I put a pad in between my 2nd layer in my ridge runner and it helps lay better and is more comfortable to me. A pad just in the hammock doesnt work well because it slides around. I also use a UC too. Also i had a klymint V and it kinda sucks. Not comfortable on the ground and the R value is like 1 or something so summer camping only.

I actually went from the Klymit V to the Tensor trail wide and it’s a game changer imo. Super comfy pad.

You can add my downvote for the Klymit V. They are pretty generous with their own R rating. Always check an independent review is what I learned using that glorified pool mat.
