Tensor Extreme

Extreme warmth for the coldest camps

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.
