NEMO - Tensor™ Elite Ultralight Insulated Sleeping Pad

This inherently does not answer your question, because it is only R2.4, but I've been using the new Tensor Elite which packs to the size of my fist and weighs 7oz. I've used it on multiple 32F nights on shaded ground. I have used my torso-length 1/8" pad to supplement sometimes, but not all the time, and have not perceived a difference in warmth. I've mostly used it for grip. In summary, I've been impressed by it and would currently not consider anything else for a sub-20L pack system Edit: meant to say Elite, not Extreme

Yeah I'm kind of in the same position. It's about what you'd expect, it's comfortable within the limits of a short, regular width pad. It's very slippery. I've used it for about 10 nights, mostly in Grand Canyon, and it hasn't leaked yet. I'm pretty good at fixing sleeping pads, so I bought it knowing that if a leak is fixable I can handle it in the field, and if it's not fixable they will warranty it for me and I could ask for something different. Like I said I've used it in combo with 1/8 ccf because that's part of my pack but I don't think that's necessary. So, in summary, I'm skeptical of it but I have yet to be given a reason to believe it's a stupid product. It's a huge gain in comfort:weight ratio compared to my Xlite.

I have about 10 nights on one. It's comfortable and hasn't failed yet. It's very easy to use compared to Neoair because of the valves. It is definitely slippery and I sometimes use a 1/8" foam under it to mitigate this. I have yet to be cold on it, even with a few nights around freezing on shaded ground. I have a similar philosophy about its durability. I'm pretty good at fixing pads in the field so if occasional leaks are fixable I'm okay with that. If something stupid fails that's not fixable, I'll be asking for a different one when I warranty it. They are pretty great at customer service and if they are going to launch a product like this I'm not ashamed to hold them accountable

It's the quietest pad I've used, except for occasional little squeaks against the CCF I use under it

The Tensor Elite has thinner material than the Uberlite

Slightly more comfortable and completely silent unless you put it on something squeaky in my 10 nights of experience

I agree but also more slippery, and obviously less durable

10 nights here so I'll help -It is not noisy at all unless you put it on top of something squeaky. -It is quite slippery, moreso than a Neoair. I often struggle to decide between putting my 1/8" foam below (protection and grip) or above (body grip). I think ultimately I will stick to below and put some Seam Grip on top for body/sleeping bag grip -It's the easiest pad to inflate and deflate in existence IMO. This is because the valves are excellent, mine is the short version so it just doesn't take much lung time, the dump valve is wide open, and the material is so supple so you don't have to be careful about folding it nicely. I was actually struck right away by how all of these things contribute to its ease of use

I mostly agree with you. I was already carrying a Thinlight on 98% of trips even with a heavier inflatable. So that's actually why I decided to try the Elite. I personally got it for less than 200 as well.

I've only slept on it for one night with a Thinlight underneath, where it got down to 35F and I felt the cold under the pad for sure but it was fine. A coworker that also bought the pad who is going on the PCT soon slept on it for a month indoors to test it out and had his rip open. He claims he just rolled over and heard it pop. [Here's a video of the damage.](https://imgur.com/a/lGLgBd3) I would *never* use it without a Thinlight.

I just checked myself, they're both listed as 1lb but the listed weight in grams puts the Eclipse at 20 grams heavier. That's not nothing, but considering it is in fact thicker, warmer, and cheaper, I too am wondering why you would choose the Tensor now if you had to pick between the two. I feel like a lot of people in this thread are trying to defend existing purchases.

Again, no one is telling you to get a new pad. The question is why you would choose a Tensor over the Eclipse.

One more time, I'm not telling people to buy anything. The literal point of OP's post is to ask why anyone would buy the Tensor over the Eclipse. And a bunch of people are giving reasons that only defend their existing purchase. Cool, great, enjoy your pad, but that's completely irrelevant to OP's question. "I don't need a warmer pad" is not a valid reason to choose one over the other.

I don't know what you're looking at but they're both listed as the same weight. And no one is asking you to buy a new pad.

Mine got a pinhole leak at the start of a thru hike. Trying to submerge it in a public bathroom sink was fun.

I’m a side sleeper as well and I stopped using my Nemo tensor so much because of the potato chip bag noise effects heh. This past winter, I’ve used the Sea to Summit comfort plus. It is easily the most comfortable pad I’ve ever used for side sleeping. And inflates and deflates easily. Highly recommend!

Is it noisy? The tensor I bought a couple of years ago is still going strong but man it’s like sleeping on top of a potato chip bag. I’m a guy that moves from side to side so it can be a problem some nights.

Same. Love the 3R (not slippery, not noisy, vertical baffles and “rails”) but really jealous of the Tensor Elite weight. Now, if Tensor made the Elite in a 25”, I’d buy it in a heartbeat.

I just spent my first night sleeping on a tensor elite. Loved it! 40F was the nighttime low temp and I was fine. It is comfortable but slippery. More comfortable than either an xlite or an uberlite for sure. I got the short version which weighed 7.5 oz on my scale. I added pillow attachment loops at a point that my Big Sky Dream Nation pillow slightly cantilevered off the head end and that worked great. The net effect is that it worked like a full length and I am 5’-10” — I wasn’t expecting that. A pleasant surprise all around.

Assuming you are attempting to go ultralight — else why post here? — you should be looking for the lightest pad that is appropriate for the target conditions. Since your intended use is summer, you don’t need a high r-value pad. Getting one would only add unnecessary weight. It will also cost more than a closed cell foam pad, and you mentioned cost as a consideration. So I’d suggest you get something like a Nemo Switchback, cut it down to six panels (about 170g / 6 oz), and *learn* to get comfortable sleeping on that. Comfort is not a fixed point, but can be achieved with a proper mindset and a willingness to practice. You are going to get a lot of non-UL advice on this subreddit, despite the stated focus. (A tell is that they don’t mention weight when making a recommendation.) Don’t spend money on a heavy pad that will move you away from your assumed goal of going ultralight. If you really want an inflatable, look at the Nemo Tensor Elite (240g / 8.5 oz). That’s the lightest inflatable option currently available and is quite comfortable.

I’ve had my eye on this. I ultimately didn’t go with it because I’m gearing my setup to be even lighter than this, but it seems nice. https://kilosgear.com/products/aerocloud-sleeping-pad-elite I went with the Nemo Tensor Elite Mummy Pad, but it is more expensive like you mentioned. For the packed size and weight, it’s a very efficient design.

Plenty of brands use 20D, the few times they've ventured lower has massively impacted durability; see the thermarest uberlite and the current Nemo tensor elite, which Nemo even admitted developed pin holes during testing. You will be fine with 20D with or without CCF underneath. I use an X-lite which is 30D I believe but previous mats I've used were 20D all fine and I'm don't exactly baby my gear lol.

Less r value but the Nemo tensor elite is at 8.5oz for the short length and you don't need to cut anything. Mine worked amazing without a problem on the PCT. I guess you could cut this down as well to save another 3oz ish.

Different use cases. Nemo tensor elite is simply made to be as light as possible, akin to the discontinued thermarest uberlite. It's only got an R value of 2.4, but it's 8.5oz The Xtherm is a full on 4 season pad with a 7.3 R value, but that comes with a weight of 15.5oz. it's direct competition would be the Nemo tensor extreme. Both of these are top of class for warmth to weight though.

Yes it's a concern. It's filling a niche formerly occupied by the thermarest uberlite, which was recently discontinued presumably because of the prevalence of durability issues. It feels a bit more substantial than the uberlite. But if I were going to rely on it, I would make sure I had a patch kit and knew how to use it, and be more careful with site selection than normal.
