Klymit - Insulated V Ultralite SL ™ Sleeping Pad

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. 

I have the Big Agnes Rapide SL and I adore the thing. I’ve been fine in temps in the teens (Fahrenheit) with a 0° rated bag and overquilt. Before that, I had backpacked with an old Klymit UL V from massdrop (anybody remember massdrop? I miss that) and it was decent, but I had no idea that I could be sleeping on a CLOUD. I can sleep on my side on the Rapide. I can sit up without my butt bones touching the ground through it! I love love love it and it’s so quiet compared to other sleeping pads. I share a tent with my SO and I toss and turn like crazy so I wanted something quiet. I haven’t tried the other pads and I normally wouldn’t give a rave review because I did get the sleeping pad for free full disclosure, but I really am SO happy with the sleeping pad. It is nearly impossible to get it back into the stuff sack tho. And it takes a LOT of pumps to fill it.

Klymic V lite/ul insulated has a 4.4 r value, between 16-20oz. It's the least costly for a pad with stats like that. I had one for about five years that I used extensively, including through the length of California on the Pacific Crest Trail. I chopped the bottom 2' off and sealed it with an iron, and only ever had a problem with leaks at the end of its life. The downside, unless they've changed it since I had it, is the valve, which you have to blow into. The inflate-sack style is nice.

Glad you had success with it! I was super hyped about it from all the accounts of its comfort. Right now my “light” ground sleeping loadout is a klymit insulated paired with Nemo switchback (most comfortable combo I’ve found outside of self inflating) with tarp and bivvy. If I’m going less than 8 miles for an overnight and either the weather is extreme winter or I have a camping partner I haul my stupidly heavy mondo king pad and split the weight of the 3 man tent between us. Been leaning towards just going fully back to my hammmock but I think I’ve determined that I need an open cell/self inflating style pad to prevent hip pain on the ground.

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.

My whole family has been using different version of these for the past few years, albeit always the insulated ones. Most of our camping is in the Rockies and even in the summer the temps get down below 0 C at night, my personal experience with uninsulated pads is not great. Generally speaking these pads are comfortable and the rail system does a good job keeping you in place. I've found they work well with a standard mummy bag (I tried it with a quilt one night and wasn't super impressed though). The fabrics are quite tough, we bring our dog into the tent and he hasn't managed to puncture any yet. On the cons side, inspite of the fabrics being tough over found these pads all develop slow leaks after ~3 years and I'll be buggered if I can find them. They lose about 50% of the their air over 4-5 hours so you find yourself touching ground in the middle of the night and having to pump a few breaths of air into it. I have a feeling it's the valves. We have 3 different generations of valve and so far it's only the newest "flip" valve that hasn't leaked. They can also be very noisy if you are an active sleeper. I recently started using an MEC Vectair 4S because it was on sale and I wanted something that would work better with a quilt. It's really comfortable, but it didn't have the rails to keep you on. I just inflate it a little less and it seems good for me. Only used it for a summer, but so far so good. One thing to note, get a pad that has a pump bag or pillow. The first generation pads we have are translucent and they get mold inside from the humidity in your breath. One of my Klymit pads has a pump bag and that is way better for reducing mold.

I tried Klymit and had the same problem. Get a Thermarest Neoair Xtherm or Xlite. I’ve used an Xlite for 4 years with no leaks.

I’d second the Naturehike pad. If OP is aiming for budget gear, might as well get something that performs. What kills me about Klymit is that they know their R value is low. But instead of updating or adjusting their design (which it doesn’t appear that they’ve done in years) they still advertise their mere up R value, I guess hoping most customers won’t understand ASTM testing. I don’t get it. Other companies have found ways to produce more budget friendly insulated pads. This company has such a massive foothold in the budget pad market - I’m just surprised they haven’t done anything in these past few years to produce a warm pad.

Love our klymit
