The best just got better
Really love my Nemo Tensor Insulated Regular with R Value of 2.7, but couldn't pass up the chance to try the improved, All-Season version that claimed to be more comfortable (thicker) and warmer (R Value 4.2) at the same weight! I tried it out during a February hike of the 75-mile Georgia section of the AT and it performed flawlessly.
Three nights, not once cold
I got the Tensor All-Season for a mid-May trip with temps overnight forecast into the high 30s. I brought a 30 degree down quilt vs my 15 degree bag as my pack space was limited. I was not once cold! I am so impressed. Durability seems more than adequate with zero issues even though we slept on rocks one night. I also worried about sliding off and that did not happen — I got the wide rectangular option as I tend to flop about from side to side. Width at 25" was adequate for this! One feedback is that I personally dislike folding up things in thirds and returning to a small sack each morning — might there be a zippered rectangular stuff sack with room to put the 1/2 folded pad and inflation bag into with less 'stuffing'? I basically did not use the stuff sack and folded the pad in half then rolled it — securing it with the included velcro strap. It's a small issue really and for someone that likes to out minimal effort out to pack up. One other tricky aspect relates to inflating — I pulled the inflation bag off a few times just before reaching full. The angle seems a bit unnatural for avoiding this — again, I'm nitpicking as it was manageable with practice. I topped off with a few breathes, too. I do wish Nemo would offer a mini pump option — or I may get a third party one for ease. Depending on how much air you get into the inflation sack, it too me up to 10-12 rolls to reach full. I also bought a sheet from another company and it did not fit so had to abandon the idea — and maybe it is not needed in hindsight. Overall, I am quite impressed and sold you might say on Nemo quality.
Nemo Tensor All Season
I bought the rectangle wide and it's been great ! Just recently brought it camping on the islands of Saranac Lake NY and it was extremely warm and comfortable. I really appreciated that thickness upgrade. Also it is very light weight, small, easy to pack, easy to inflate. All around great sleeping pad!
Top Tier Pad On The Market
Still remains one of the best pads on the market currently. I've used the Regular Wide size several times for backpacking and it's a hard one to beat. I've tested it 60 degree temperature and 20 degree. Both times it did not disappoint, especially in 20 degrees. It's light, super packable, and very quite compared to other air pads. The only reason I am giving it a 4/5 is because it is not super comfortable for side sleepers. Though this issue can be resolved by adding a switchback underneath for additional padding.
Fits my Big Agnes Daisy Mae perfectly
Though I have yet to use this pad, I can confidently say of the ~7 pads I've owned, this is the best. It packs down ultra small and is incredibly lightweight, comfortable, and the dimensions (70"x25") fit my BA sleeping bag's integrated pad sleeves perfectly. I'll have to take Nemo's word on the R value for now, but I'll try and update this review once I test it. It's a bit crinkly when you move around and I wish it had elevated sides to hold me in place at night, but I'm not so bummed as to remove a star from my rating. Overall it's a great pad :)
Still a market leader with two quirks.
I still own the older Tensor Insulated, and also got the new all-season pad for a bit of extra warmth. Compared to the older pad, the face fabric is a bit louder and more crinkly feeling, but this was apparently done for durability. What I wish Nemo would do is make a mummy taper in the reg/wide and long/wide versions of the Tensor, since it's the lightest pad in the lineup. The Hornet, Dragonfly, and Mayfly 2 are all 50 inches wide at the head, but then they taper at the foot. I'm not the only one who would like to fit two wide pads in a UL 2 person tent. Confusingly, Cascade does the opposite, offering tapered sizes in the Neoair and rectangular floors in the Hubba Hubba.
Best all around pad in the market.
I bought the large long which happens to be the exact same weight and size as my uninsulated sleeping pad. It's pretty incredible for a 5.4R rating pad. Also first night was the most comfortable I've slept on a light weight backpacking sleeping mat probably ever. Colors are fantastic. The bright orange is great for emergency signaling and the grey will go with most tents on the market. I'm convinced Nemo makes the best sleep gear in the market. Wish I had a spoon bag to go with it. Picture below of waking up refreshed in the Grand Canyon.

Amazing sleeping pad
So happy with my new tensor sleeping pad. Very lightweight and the 3.5 thickness is a massive upgrade from my old sleeping pad. Cannot go wrong with the quality of Nemo.
Wife loves this mattress
We had a chance to sleep out a couple of nights ago - it was my wife's first time using this mattress. She loved it - very comfortable and warm. I can't believe it's so small. I also appreciate the inflator!
