NEMO Tensor™ Extreme Conditions Ultralight Insulated Sleeping Pad

NEMO Tensor™ Extreme Conditions Insulated Sleeping Pad

True four-season warmth. Still ultralight.

The Tensor™ Extreme Conditions (EC) marks a major leap forward in cold-weather sleeping pad design. Built for high-altitude, early-season, and winter backcountry use, Tensor EC delivers a category-leading 8.5 R-value while maintaining an exceptional warmth-to-weight ratio—making it the warmest ultralight air pad NEMO has ever produced.

At the core of Tensor EC is NEMO’s innovative Apex™ baffle construction, which suspends a record four layers of floating Thermal Mirror™ insulation inside the pad. This strategically layered design traps heat efficiently without creating the crinkly noise often associated with reflective insulation. The result is remarkable warmth, silent performance, and 3.5 inches of stable cushioning for deep, uninterrupted sleep—even on frozen ground.

Designed for rugged terrain, Tensor EC pairs a 40D nylon bottom for improved puncture resistance with a premium 20D nylon top that offers a soft, lightweight sleeping surface. The updated Laylow™ micro-adjustable valve performs reliably in extreme cold (down to -20°F and below), allowing precise inflation and deflation with gloves on. Paired with the included Vortex™ pump sack, inflation is fast, moisture-free, and effortless at elevation.

For PCT hikers tackling the Sierra early season, winter backpackers, or anyone prioritizing warmth without the bulk of foam pads, Tensor Extreme Conditions sets a new benchmark for cold-weather comfort.
