"Because of this I bought the Nemo Tensor which is much quieter than the Sea to Summit."
"not loud"
"The NEMO Tensor is a quiet pad. ... No potato chip bag crunchy noise"

"I sleep all night and no body aches."
"The tensor has a micro adjust valve to that allows you to adjust the pressure to what works for your body. ... Using that micro adjust valve to release some air while you re laying on the pad is a serious game changer. ... Allows the pad to contour to your body versus feeling like a hard bed."
"I’m heavyset and getting old with back injuries to boot. I sleep really well on the tensor, better than I thought possible in the woods."

"potato chip bag noise effects"
"If noise is a dealbreaker for you, definitely listen to the people who say it is loud. It is. By any sleeping pad standard."
"I upgraded from an older therm-a-rest to a Nemo, it is thick, warm, and comfy but noisy!"

"I can feel the cold seep through my Nemo Tensor Insulated (R4.2) from around freezing."
"I’m a hot sleeper too but find my tensor trail is too cold below 35F"
"For fall/winter trips I use a nemo tensor, and if it is below 50 I will add a foam pad under the nemo to achieve an R value of ~5."

"I had a Nemo Tensor straight POP with a one-inch tear from a extremely tiny burr on the edge of my quilt pad strap!"
"The Nemo tensor has failed on me twice now (the second one was a replacement). It slowly loses air, and so you are on a 3 hour schedule until you are reinflating it."
"I’ve had multiple Nemo tensors and they all leaked and tore beyond repair."

"I am a flopper and tended to roll onto the edges, which made them collapse and dumped me onto the ground."
"I find horizontal baffles extremely uncomfortable … it feels as if anything closer to the edge falls down and doesn’t give any support."
"The Tensor I find perfectly OK if I get the inflation level right, but its not good on the side so I usually just avoid side sleeping with it."

I think the Nemo Tensor Trail should be fine for you. I spent the last few years backpacking in the Ohio river valley (and elsewhere in the east coast and south) on a pad with a 2.5 R-value and was never once cold. I sleep notably warm as well, so I even used that pad down to 5F, but the reality is that winter in Virginia is rarely cold enough that this pad (especially if paired with a foam pad) would not be sufficient for you.
r/Ultralight • Sleeping Pad Advice ->If I ever buy another inflatable pad, it'll be a [Nemo Tensor Trail](https://www.nemoequipment.eu/collections/sleeping-pads/products/tensor-trail-insulated-ultralight-sleeping-pad). Of all the inflatable options, it's simply the best blend of comfort/weight (assuming you avoid cold temps like I do) The horizontal baffles on the XLite are nowhere near as comfortable
r/Ultralight • Sleeping pad analysis paralysis ->Nemo Tensor Trail is the correct answer.
r/CampingGear • Lightweight Air Mattress Recommendation ->The Nemo Tensor line of pads is what you need. I haven't messed with the Elite (8.5 oz / regular mummy), but the Trail (13 oz / regular mummy) and Insulated (14.1 oz / regular mummy) have treated me well this year. If you want to get full-season use, just get the insulated—it has an r-value of 5.4 and is only \~1 oz heavier.

r/Ultralight • save me from sleeping pad hell pls ->I’ve used mine down to 20 degrees. Any colder and I use a foam pad underneath. The tensor is awesome, especially when paired with the right bag for conditions.
r/CampingGear • Nemo Tensor Trail ->I have a Nemo Tensor Insulated (Reg rectangle) and absolutely love it. It's super comfortable, I haven't found it to be noisy at all, and it's quite light.
r/REI • Looking forward the unicorn of a sleep pad. Quiet. Side sleeper. Lightweight ->I can’t comment on the others but I have had a Tensor Insulated for a few years and absolutely love it. I’m a side sleeper and I’ve used it down to 30F and it gets the job done but that’s about its limit. If I were going to be in temps consistently that low I’d put foam under it.
r/Ultralight • Quiet side-sleeper pad for 30+ F temps ->No it has a good baffle structure. Amazing for its weight. I inflate it, then let bits of air out so that my shoulder is about an inch off the ground when I’m on my side and then it’s perfect for the night.
r/Ultralight • Quiet side-sleeper pad for 30+ F temps ->I’d second the Nemo Tensor all season ultralight insulated. I waited till it went on sale and snagged it for about $150. With an R 5.4 it may actually be too warm for your summer trip but I’ve used it almost all year around. Very comfy when I was 79kg and incredibly comfy now when I’m 69kg. I toss and turn a lot so I went with the wider option. If I could sleep without rolling I woulda gone with the mummy regular to save the weight. If you’re not needing as high an R value, the Tensor Trail can save you weight and money at R 2.8. If you can find a crazy sale, the Tensor Elite saves you almost half the weight, but I believe it is a relatively new pad with minimal time to see how well it will hold up to time in the wild.
r/Ultralight • Sleeping mat question ->For -5C and durability I would personally take the Thermarest X-Therm mummy. R7.3, 440gr (although mine weighs 460gr in reality), and a 70D material on the underside. Anecdotally, I can feel the cold seep through my Nemo Tensor Insulated (R4.2) from around freezing.
r/Ultralight • Sleeping pads ->Same here - Tensor Insulated down to about freezing when I can start to feel the cold seep through. The Tensor Insulated has been replaced by the significantly warmer Tensor All Seasons, and that would be my recommendation.
r/Ultralight • Quiet side-sleeper pad for 30+ F temps ->After reading a lot of advise like this, I bought a rectangular wide pad for my thru hike (Nemo Tensor Insulated). When my partner joined for a bit with an X-Lite regular mummy, it turned out that she (5ft) much prefers the wide pad, while I (6ft side sleeper) sleep just as well on the regular mummy (even though I, too, often kick a knee up). Obviously she took the Nemo back home to save me some weight for the remainder of the trip. Just goes to show how personal these things are.
r/Ultralight • Sleeping pad analysis paralysis ->I have both pads, notice no difference in comfort, and sleep equally well on either one. Guess I’m just an easy sleeper - certainly after a long hike!
r/Ultralight • Sleeping pad analysis paralysis ->Both Thermarest and Nemo pads work for me, and I suspect many others would as well. Regarding shape, I think I actually need *less* space than someone who sleeps on their back. Regular mummy pads work great for me.
r/Ultralight • UL comfortable sleeping pad for side sleepers? ->3 season tensor is really what you should get unless you wanna winter camp. I love camping but winter camping is not for everyone. But no doubt get the tensor. 10000% https://www.rei.com/product/228438/nemo-tensor-trail-ultralight-insulated-sleeping-pad?sku=2284380002&store=&CAWELAID=120217890018031554&CAGPSPN=pla&CAAGID=147758271279&CATCI=pla-2022408626626&cm_mmc=PLA_Google%7C21700000001700551_2284380002%7C2022408626626%7Cbrand_flag%7C9920629669&gclsrc=aw.ds&gad_source=1&gad_campaignid=9920629669&gbraid=0AAAAAD_DTlxwAE6K8qThhTEh4hPO024V0
r/CampingGear • Any strong reason to choose one over the others? ->Unless you are camping in winter get a Nemo Tensor Trail. The 2.8R rating it has will be good down to freezing, it wil crinkle way less, and is much lighter.
r/CampingGear • Any strong reason to choose one over the others? ->You'd have to sleep pretty cold for a 2.8r rated mat to not be enough gound insulation for 3 season camping. Ground insulation doesn't generate or trap warmth around a sleeper, it just reduces the heat loss to the ground. Whether you are a cold or warm sleeper, that rate of heat loss will be the same.
