Though we didn't experience issues with our test model, there are multiple concerning user reviews and online forums where folks state that their Tensor Insulated pads had slow leaks around the baffles. When we reached out to Nemo for comment, they stated that they have analyzed the claims of the Tensor pads having weld leaks and determined the leaks are caused by small abrasions on the ultralight 20D fabric. They also stated that they are currently working closely with their factory partner to improve build and fabrics and have seen a steep decrease in leaks during this past year. However, since it's hard to know how long a retailer's stock has been on the shelves, it's entirely possible that you may end up with a defective pad if you purchase this product, and therefore, we'd advise against buying it at this time.
Nemo also says there is no recall for the Tensor Insulated at this time, but they will honor their lifetime warranty on their products. Their customer service rep told us they are happy to repair or replace any pads with defective issues.NEMO Tensor Insulated Review
Our Verdict
Our Analysis and Test Results
If you do a good job protecting this pad from external punctures, it is a competitive alternative to more costly mats like the Top Pick winning Sea to Summit Comfort Plus Insulated or the Editors' Choice-winning Therm-a-Rest NeoAir XTherm. Continue reading to see why we loved the Tensor and why it might be the right addition to your kit.
Performance Comparison
Comfort
The Tensor ranked high in the comfort metric. The relatively smooth surface welcomed a solid night's sleep. Three inches of thickness absorbed any irregularities like grass clumps and provided lots of cushion for side sleepers. For those who can't get past the crinkly but high scoring Therm-a-Rest NeoAir XTherm, the Tensor provides a much quieter night's sleep, and our reviewers found it a bit more comfortable because the edges are less prone to collapse.
Weight and Packed Size
Low weight and packed size are two great reasons to choose this pad. Coming at just 15 ounces, the Tensor turned heads and didn't weigh us down. If your most important metrics are weight and comfort, this is the pad for you. Winter travelers will likely be better off with the 15-ounce Therm-a-Rest XTherm. If you're looking for true ultralight comfort, the Therm-a-Rest UberLite reigns supreme with a high comfort score and weighs just 12 ounces. Nemo also offers this pad in uninsulated, short, and tapered variants that further increase weight savings.
Warmth
With an R-value of 3.5, some of our testers still felt cold while sleeping on the snow, so we recommend pairing this pad with a foam one like the Therm-a-Rest ZLite Sol for forays into winter conditions. For three-season backpacking, the Tensor proved up to the task.
Ease of Inflation
The latest incarnation of the Tensor employs a micro-adjustable valve so you can easily dial in your firmness level, but what really impresses our testers is the Vortex Pump sack. The wide version of this pad takes a lot of air, and the pump sack makes filling the pad a relatively quick and easy process. Simply connect the pump to the valve, open up the end of the sack, so it fills with air, and roll the sack closed, so all the air is forced inside the pad. We think it works better than similar pump designs from Thermarest and Klymit.
Durability
20D PU polyester ripstop forms the outer material for this pad. This type of material represents an aggressive weight savings approach to pad design. We were anything but gentle with the Tensor, using it directly on sharp granite rocks and grassy substrates, and subsequently, the pad no longer remains inflated for a whole evening. If you end up purchasing the Nemo, we recommend using it in conjunction with a ground tarp or tent. Treat it well, and it'll likely reward you for years to come.
Value
We feel this is a fair price compared to other pads on the market. Some pads we like more are less expensive like the REI Flash Insulated, but others are more expensive like the Therm-a-Rest NeoAir XTherm.
Conclusion
The Tensor is a great lightweight backpacking pad with high performance at the cost of durability. Our testers found it super comfortable and an improvement over pads with horizontal baffles. If you're looking for one pad for your weekend adventures and tend to treat your gear with care, the Tensor has impressive specs that make it a top competitor.
