The Nemo Tensor Extreme is a next-generation ultralight sleeping mat built for backpackers who refuse to compromise on warmth. Combining industry-leading insulation with a surprisingly low weight, it offers an exceptional warmth-to-weight ratio, making it a standout choice for cold-weather trekking and year-round backpacking.

With a class-leading R-value of 8.5, the Tensor Extreme is one of the warmest ultralight sleeping mats available, capable of handling freezing ground conditions with ease. Its advanced construction uses four layers of Thermal Mirror™ insulation, reflecting body heat back towards you for maximum efficiency, ideal for extending your backpacking season into colder months.

Despite its impressive insulation, the Tensor Extreme remains remarkably lightweight, with some versions coming in at just over 500g. This makes it a rare find: a true 4-season-capable mat that still fits comfortably into a lightweight backpacking setup.

Designed for restful nights after long days on foot, the Tensor Extreme features 9 cm of cushioning for excellent support on uneven ground, Apex™ baffle construction for even weight distribution and stability, and a quiet internal structure to eliminate crinkling noise. The result is a mat that feels stable, supportive, and comfortable, even on longer trips.

Features

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

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

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

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

Impressively quiet for uninterrupted sleep (and happy neighbours).

The included Vortex™ pump sack provides easy and fast inflation, saves breath at elevation, and minimises moisture entering the pad.

Available in a wide range of sizes to easily pair with the rest of your sleep system.

What's Included: Stuff sack, Vortex™ Pump Sack, Velcro Strap, Repair Patches.
