Reactor Extreme Thermo Liner

The THERMOLITE® Reactor Extreme uses our super-insulating 110g/m3 to seriously increase sleeping bag performance.

The spacious design is slightly tapered from head to foot to reduce weight and increase thermal efficiency, and the drawcord hood can be cinched down for extra warmth when required. This knit fabric also has serious stretch to it, making the Reactor Extreme the ideal liner for the restless sleeper.

Increases sleeping bag performance by up to 25F (14C) with super-insulating 110g/m Thermolite fabric.

Thermolite is a hollow core fibre that provides extraordinary warmth for its weight and remains extremely breathable. Spacious design allows for a comfortable night's sleep, even when the mercury plummets. Perfect for extending the season of your sleeping bag.
