Tensor™ Extreme Conditions represents a new chapter in NEMO backcountry pad innovation. With its Apex™ baffle internal structure, Tensor EC toasts the competition, achieving an 8.5 R-value and a mind-bending warmth-to-weight ratio. Now the warmest, most insulating ultralight pad on the market, it’s also still the quietestpad in its class. (Dreamy, right?)

Using distinctly shaped baffles, the Apex™ design evenly suspends a record four layers of insulating Thermal Mirror™ film inside the pad. The strategic placement and number of layers combine to produce incredible warmth at as little as one pound, making this pad a winter-worthy companion that won’t weigh you down. Just as important, the floating construction prevents annoying crinkling noises so you and your camp partners can sleep soundly even on the most restless nights. Warmth, quiet, and 3.5 inches of stable cushioning together make Tensor synonymous with comfort.

Tensor Extreme Conditions ushers in improved puncture-resistance and strength with a 40D nylon bottom to protect the pad from tougher terrain. Meanwhile, the premium 20D nylon top offers a soft, lightweight sleep surface. The pad’s Laylow™ valve also gets a polish, removing unnecessary elements and significantly improving the performance and ease of use in all conditions — especially colder temperatures. Plus, it still effortlessly pairs with our Vortex™ pump sack to inflate in mere minutes, without introducing excess moisture into the pad.

  • Apex™ baffle design suspends more insulating layers than ever before, strategically spaced for the highest R-value possible — 8.5.

  • Four layers of floating Thermal Mirror™ metallized film provide quiet insulation with an unprecedented warmth-to-weight ratio.

  • 3.5 inches of stable, cushioned loft for incredibly comfortable nights. 

  • Impressively quiet for uninterrupted sleep (and happy neighbors). 

  • bluesign® approved premium nylon fabrics shave grams while offering superior puncture- and tear-resistance. 

  • Included Vortex™ pump sack provides easy and fast inflation, saves breath at elevation, and minimizes moisture entering the pad. 

  • Improved zero-profile, multifunctional, microadjustable Laylow™ valve offers customized inflation control, even at -20° F and below.

Comfy Sleeping Pad

It really is comfy and quite quiet to some other brands. It suits me perfectly as a side sleeper. It also kept me warm on sub-zero nights. It’s also easy to inflate and relate. Definitely recommend it.

Best sleeping mat

After a recomendation from John here at Ozbackcountry I bought the Nemo tensor alpine and it was the best thing I have done . After coming from an Exped this Nemo is next level comfort , no rolling off it and none of that Exped noise . I got the wide long and that extra bit of width is great . It has good 'R' value and I was not cold on it up in the VHC . The guys at Ozoutback know their stuff and I found John only too happy to spend time on the phone with me so I got the correct product . Highly recomend Ozoutback and the tensor alpine .

Being 6 foot 3 and boney, I’ve always had trouble finding a good pad that would cushion my hips and shoulders when on my sides. These are incredibly thick, slept on many rocks without realising it. Only got to test it in -2 degrees but it was very warm. Looking forward to testing it in the winter
