Whether you’re bivvying at altitude or pitching up in the snow, the Tensor Extreme is a lightweight, sub-500g insulated air mat that doesn’t skimp on sleep quality. It boasts an impressive 3.5 inches of cushioned loft, using unique Apex baffles designed for stability and even weight distribution. Upgraded insulation consisting of four layers of floating metallized film gives a best-in-class R-value of 8.5, making this mat suitable for the most extreme winter camps and mountain missions. But unlike most other insulated mats, it’s significantly quieter too, without that crisp-packet crinkle that makes it tough to drift off. If you’re looking for a pinnacle sleeping pad for the most demanding conditions, the Tensor Extreme cannot be beaten.

Sustainability Through Longevity - NEMO products are covered by a Lifetime Warranty against material and workmanship defects
The idea of NEMO was born one turbulent night on the side of Mount Washington while Cam Brensinger spent a sleepless five hours in a poorly designed bivy. That night he realised how much opportunity there was for thoughtful design as part of the equation of enjoying adventure. And, coming down off the mountain the next day, he resolved to tackle that challenge. Three days after graduation from Rhode Island School of Design, he founded NEMO Equipment.
