The Nemo Tensor™ All-Season gives greater warmth than the Trail for four-season use with only a slight increase in weight and bulk. Designed to be a go-to mat all year long, it straddles all seasons and keeps its reputation for low-decibel dozing.

The mat’s interior features Nemo’s proprietary Spaceframe™ baffle design, which utilises low-stretch fabric trusses to create stable support and provide just the right amount of give - all while avoiding any wobbly waterbed feeling. Inside each baffle are suspended two layers of ultra-thin, metallised Thermal Mirror™ film, which efficiently reflect body heat and contribute to the mat’s overall 5.4 R-value. The layer’s clever floating construction eliminates the crinkling, crunchy sound that many insulated air pads are known for, earning Tensor a reputation for peace and quiet under the stars.

Covered with premium, durable 20D (top) and 40D (bottom) nylon, Tensor Trail is better protected than most against punctures and tears, and - like all Nemo sleeping mats - it includes a Vortex™ pump sack. The Vortex pump effortlessly mates with the mat’s zero-profile, microadjustable Laylow™ valve for easy inflation in just minutes.

  • Two layer of floating Thermal Mirror™ metallised film provide quiet insulation with an unprecedented weight-to-warmth ratio.
  • Impressively quiet for uninterrupted sleep (and happy neighbours).
  • Spaceframe™ baffles offer unparalleled stability and weight distribution, using low-stretch, die-cut trusses that eliminate springiness.
  • 3½ inches (9 cm) of stable, cushioned loft for incredibly comfortable nights.
  • 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 minimises moisture entering the mat.
  • Improved zero-profile, multifunctional, microadjustable Laylow™ valve offers customised inflation control, even in cold temperatures.
  • Available in a wide range of sizes to easily pair with the rest of your sleep system.
  • Includes Vortex Pump Sack, Stuff Sack, Velcro Strap and Repair Kit.

Togs and R Values: Typically used in the British textile industry, one Tog corresponds to the heat insulation capability of clothing etc which maintains a temperature difference of 0.1°Kelvin while passing a heat flux of 1 Watt/m2*. Some manufacturers (mainly US ones) give an R Value for the insulation properties of their mats. By this they mean an imperial equivalent (°F-ft2-h/Btu). To convert Imperial R values to Togs, multiply by 1.76228. To confuse matters there is also a metric R value, more properly called an RSI value (10 Togs = 1 RSI).

The higher the Tog or R (or RSI) value the better the insulation provided.

If you aren't totally confused by the above you should add to the mix that testing for R/Tog/RSI ratings is not by any means an exact science and that it is also expensive so, it is alleged, some figures that are given may be acquired by doing little more than taking a competitor's figure and adding a pinch for good measure. Of course, who is alleging what about whom is also not easy to ascertain!

*NB One Tog was originally a war time measurement of the amount of warmth retained by a typical male wearing a three piece suit - it originated from research done in the North of England - hence the term tog (though this in turn is thought to originate from the Roman word toga)!
