I purchased the insulated, 25" wide option. This is an upgrade from my Nemo Astro Lite non-insulated, 20" wide. The first time I used this pad, the night temps dropped into the upper 30F's. I'm transitioning from a sleeping bag to a quilt sleep system.Pros: The 4.2 r-rating for this pad is immediately noticeable. Wearing a thin base layer, I never felt cold from the ground. Considering all the metallized film used to reflect heat, the pad is remarkably quiet. As a side sleeper, the 25" wide pad allowed me to extend my knees and arms and roll over without feeling like I was going to fall off the pad. The 25" pad fits perfectly in my one-man tent. The pump sack makes inflation easy with fewer breaths.Cons: At 1lb 6oz (packed weight), the Tensor is slightly more ... MoreI purchased the insulated, 25" wide option.

I expected this given the larger size and increased insulation. One design improvement would be to add a pull tab to the pump sack where it connects to the pad valve. Care needs to be taken not to I pull the valve out of the pad when detaching the pump sack. Cold hands could make this task more difficult. I'm interested to try the pad in warmer weather to see if it's too warm...but that will have to wait until spring.Overall, I'm very happy I upgraded my sleeping pad. Catching it on sale was a bonus.

I have purchased 4 of these sleeping pads (regular wide) because it is so incredibly comfortable and keeps me warm in the winter. Unfortunately, ALL 4 of them have FAILED. After just a few nights on trail, they begin to deflate for no reason. I take very good car of my gear and always make sure the area I put my pad on is free of debris and most of the time, I put the pad on top of a foam cell pad and somehow each one I have purchased begins to deflate after a few nights of use. Most of the leaks have been extremely slow and I have been able to get a few hours of sleep before having to blow them up again. However, my most recent trip to the Smokies, my BRAND NEW PAD got a big leak somehow the 2nd night on trail and I had to blow it back up every 15 minutes, which is ...

The pad is very warm and comfortable but pretty soon, after just a few nights sleeping on it, it will begin to deflate very slowly. I have put the pads in a tub with water trying to find the leak and have been unsuccessful in finding the leak to try to patch it, which makes me wonder if the valve is defective? The result is that I purchase a new pad (hence the 4 purchases). At this point, I am done and have purchased a pad from a different company.

I cannot say enough good things about this pad. From the very effective insulation, to the thoughtful quilting pattern design (to keep everything where it should be), this pad is a bar down series hat trick.The vortex bag works great. It takes me a total of about 6-7 easy breaths to fill the pad. No more getting dizzy, and no filling the pad with condensation that will freeze. (Tip, don't blow directly into the vortex sack, blow about 6 inches from the bag. This will cut down on any condensation going into your pad).The stuff/carry sack is thoughtfully sized so there's no fighting this thing in. Just drops right in. I also really appreciate the integrated repair kit. The 25" size is FAR better than the standard 20" size. I don't know who sleeps on those, but if ...

I absolutely recommend springing for the 25". The added weight is negligible, and the cost is worth it to sleep comfortably, which this pad delivers on.Finally, the two part fill/bleed valve is wonderful. It can be a bit challenging to separate the two without opening the full valve, but a little care and practice makes it happen. The ability to make micro adjustments in the pads fill is worth the extra effort.

I bought this pad for the second time because the first one I bought from an in person retailer. After blowing it up for about 10 minutes I packed it up and took it to 4 pass loop for its first of many trips with me. Long story short the pad had been bought before and returned. The previous owner had put a small hole in it so I didn’t notice the leak when I tested it. I woke up every 3 hours to blow it back up and was extremely annoyed. I returned it but decided to wait to buy a new one and save the money. Moosejaw had the best price available even with Black Friday sales and I can tell it is a completely unused product. That might not sound like much but after 4 cold and uncomfortable nights because of that issue I can say it is a huge deal. The pad it’s self is ...

That might not sound like much but after 4 cold and uncomfortable nights because of that issue I can say it is a huge deal. The pad it’s self is awesome and held air for around 18 hours before I was sure it was good to go. The comfort is unmatched and the biggest plus for me is the lack of noise when laying or moving on the pad. I’ve spent nights on many other high end pads and my friends have made comments on being woken up by me turning over because the sound is so loud. The biggest competitor is the big Agnes rapide and I cannot say anything about that one but at the same price and my personal experience I can say this is a safe bet well worth the money
I'm coming from a bad break-up with a Big Agnes AXL Insulated Long/Wide. I really should have listened to my friends and family (on this site and others) that told me the AXL would let me down. And it finally did. I thought I could fix it, I really tried. Some bonding here, a little mend there... but ultimately at 4:52am on a cold Sunday morning in February, it quit on me. It just left me there; laying on the cold, hard ground. All of the support and comfort - just GONE... in an instant. I was so depressed. This was to be my long time trail companion. Long walks along winding paths in the fall, relaxed naps under a canopy of shade trees, just so it could dump me on the ground 8 miles into the backcountry. Oh sure, I suppose I should be grateful for the good times we ... MoreI'm coming from a bad break-up with a Big Agnes AXL Insulated Long/Wide.

All of the support and comfort - just GONE... in an instant. I was so depressed. This was to be my long time trail companion. Long walks along winding paths in the fall, relaxed naps under a canopy of shade trees, just so it could dump me on the ground 8 miles into the backcountry. Oh sure, I suppose I should be grateful for the good times we had, and at only 17 oz it was delight to spend time with. But that time is over, I've found something new. Something that friends and colleagues by the thousands assure me will treat me better.Welcome to the new Nemo Tensor Insulated L/W. Yes it's a little heavier than my previous engagement at 20.7oz, but it's also got a warmer personality @ 4.2R. So far it's only made it to 1 campout but with good results. My hopes are for a long-term relationship, something the AXL just couldn't give me. Time will tell, but the early stages of our courtship are promising.So the particulars: Dual valve system does make it quite a bit easier to deflate and stow since the entire valve comes out allowing nearly instantaneous air removal, especially when folding and rolling it up. Filling is also very easy - Nemo provides a pumpsack with the Tensor (and they should considering the price of the Nemo Tensor) and it's pretty good. However it's dead weight as it's ONLY purpose is as a pumpsack. My highly preferred alternative is the Big Agnes Pumphouse Ultra pumpsack/drybag. Nemo's attempt works great for the 1 thing it does. But for the added weight in my pack it's just NOT nearly as good nor as useful nor as light and multipurpose as the BA Pumphouse Ultra (https://www.rei.com/product/115082/big-agnes-pumphouse-ultra). I had to 3D design and print an adapter for the BA-to-Nemo, and it was totally worth it. You can find my adapter for free on Thingiverse if you need one (weighs 5grams). I've always paired my air pads with a closed cell foam pad like the Therma-a-Rest Z-Lite Sol or Nemo Switchback for added thermal support, pad protection and camp lounging. The closed cell Nemo Switchback was under my Big Agnes AXL that fateful morning in February and made the few remaining hours of getting back to sleep possible and relatively comfortable, considering the alternative. The pillow baffle is comfortable and I feel it contours better to roots and rocks you may be forced to sleep on. The advertising is accurate - I was able to get mine down to 3.25" x 7.25" @ 20.01ozEnd comments: The Nemo Tensor has a great warranty behind it, I hope I never have to use it. It is comfortable at 3 inches and a decent 3+ season R-Value of 4.2. Super easy to inflate and even easier to deflate. The pumpsack it comes with is fine for car and base camp, but if you're going for the lighter side of things and need to protect your down sleeping bag anyway - I'd highly recommend pairing it with the BA Pumphouse Ultra (NOT the Platinum).
The Nemo Tensor Ultralight Insulated Sleeping Pad is fantastic. The build of this pad makes it easy enough to set it up to inflate and go about whatever else needs to get setup or done. I would recommend unfolding it and just leaving it to inflate naturally. If you stand over it expecting it to inflate, on its own, quickly, you may find yourself frustrated. In my experiences with it, leaving it to inflate on -its- time, the top-off required by you when you are ready to lock the value will be minimal. And you will have to top it off, if you are looking for a pad on the more firm side of comfort. If you want a little give in the pad, then you might be fine to lock off the value once it is done inflating on its own. Just know going in, and be prepared to add a bit of ...

Just know going in, and be prepared to add a bit of breath if you are not happy with the self-inflation.I love this pad and would recommend it to anyone I speak to about it, with the one caveat.I get cold easily, especially lying on the ground and this pad kept me away from the cold nights. The -1 star is for the advertising. To me, this particular feature of self-inflation is one of the deciding factors for people researching what to buy and the verbiage allows for the possibility that when we see self-inflation, one might expect it to do all the work. I do leave room for the possibility that this way of thinking could be isolated to me, while others would assume they would have to put some work into it, but I think they should preface, somewhere on the packaging, that we may have to breathe some life into the pad.I feel like what I am asking for maybe most people will already know this, but when you are putting down that much money for a tool, going the extra mile to inform the customer, without them needing to have prior knowledge, isn't asking too much.A major function of the pad is about being hands off and for me, there is room for improvement in communicating and setting a transparent expectation of what exactly we are getting when we buy this product.Needing to breathe into the pad isn't a big deal and having thought about it for a while now, I feel silly for expecting it to completely inflate on its own.If you are looking for a pad that doesn't literally take your breath away, this should be on your list of considerations.
I have had this pad for about a year. I have used it in my month long backpacking trip to Norway and I used it for my mountaineering expedition in Argentina. Overall, I have about 60 days sleeping on it. I brought this as my main sleeping pad for my Mt. Aconcagua expedition and used it in 80 degree weather, all the way down to -25 degrees. It has held up to the harshest conditions and I have had no issues. I paired it with a closed cell foam pad and a mountaineering bag for those cold nights and extra protection, and I didn't feel any cold spots on my back. Our tents would usually have gravel and sharp rock poking through the floor and I was almost certain it would eventually pop but it held up to it all. In the mornings the corners would be frozen solid from the ... MoreI have had this pad for about a year.

In the mornings the corners would be frozen solid from the condensation but it still didn't break. I know blow up pads can be hit or miss with good seals and durability but this is my 2nd Nemo pad and it has made it through all of my extreme adventures. If you're on the fence about getting it because of the mixed reviews, get this pad! Just be vigilant when using it and you should be fine. And Nemo has a great warranty service and will help you if any issues arise
I am a light sleeper, I toss and turn a lot, and I primarily sleep on my side. I specifically chose the Tensor because it is reputed to be the most comfortable lightweight pad, and the most quiet. It did not disappoint! The chambers design rather than the baffles is very supportive and it is quiet when I turn over at night.One helpful thing that I have seen others do and that I did myself was to put dots of silicone on the underside of the pad to keep it from slipping around inside my tent. It is easy to do and will make an outstanding sleeping pad even better.The only thing that I could say about this pad that isn't excellent is the pump sack, but I don't feel that it is worth subtracting stars for.

The pump sack sorta works, but requires the user to blow into it rather than being able to shake it to try air. My Exped Schnozzle pump sack fits the Tensor though and it works so much better, it also doubles as a compression sack for my top quilt.So is this pad worth the cost, especially when compared to some less expensive competition? My opinion is that the sleep system is the first system in precedence to upgrade. If there is any system that I would not recommend skimping on for, it is sleep, so yes I feel that the Tensor is well worth the price.
I've been backpacking for nearly 30 years and have used a ton of sleeping pads. I needed to replace mine but I couldn't decide between this sleeping pad and the Thermarest Neo Air XLite. They both had very similar specs and price, so I decided to buy them both in the regular mummy size for an 8 day backpacking trip with my daughter in the Patagonias. She used the Thermarest and I used the NEMO. We had all weather from freezing to warm. The two models really are almost identical from a practical perspective. About the same size, weight, R-factor and thickness. They were both very comfortable, even on rocks and roots. But there are two factors where we both preferred the NEMO over the Thermarest.

About the same size, weight, R-factor and thickness. They were both very comfortable, even on rocks and roots. But there are two factors where we both preferred the NEMO over the Thermarest. First, the design of the pump sack is much better on the NEMO. The pump sack for the Thermarest was really hard to get on and off, didn't inflate as easily or seal as well. The NEMO was easier and quicker to inflate. Second, the Thermarest was much noisier. I know this is no surprise as it is a common complaint, but having the two next to each other it was really obvious how much quieter the NEMO was. This was the biggest reason I wanted to try the NEMO in the first place since I don't like a noisy pad. I did not have any quality issues with either as some have reported. Both held up very well. In fact, because I was concerned about some of the reviews about poor build quality, before I left for my trip I inflated the NEMO, loaded it up with over 200 pounds of weight on top on hard ground and left it for two days. At the end of that time there was no noticeable loss of air or defect. So, in the end, I gave the Thermarest 4 stars and the NEMO 5 stars.
Short version: The valve had a slow leak.Long version: I tested this pad at home, but did not lay on it longer than 30 minutes. When I took it on the trail, about 45-60 minutes into sleeping I woke up cold: the pad had deflated and I was sleeping on the ground. Since it was my first time out w/ the Tensor I thought maybe I had messed up something or inadvertently deflated it in my sleep. I turned on the light, re-inflated it, and very carefully closed the valve per the instructions I read off the their website and practiced before at home. Again, 30 minutes later or so, I'm on the ground the again. I could feel it deflated and I could hear air escaping the valve... it sounded like it was bubbling out. Needlessly to say, I slept horrible. I was on a 3-day trip on ... MoreShort version: The valve had a slow leak.Long version: I tested this pad at home, but did not lay on it longer than 30 minutes.

Needlessly to say, I slept horrible. I was on a 3-day trip on the AT in Va. The next night, I figured out a work around deflated slowly... but this time I was able to keep it inflated for 1-3 hour increments, depending on how much I moved in my sleep. Not great, but better.Conclusion: For this price point, the product really shouldn't fail... let alone the valve. I don't think this was user error. I read online of other valve failures but thought people were just idiots... so, I may be an idiot, but it failed on me too. I've returned it.Pros:- It was the most comfortable pad I've ever used. I wanted so bad for it to work.- Warm: Temps were in the 30's and when the pad was inflated, I was totally warm.Cons:- The valve failed, therefore everything else doesn't matter.
