Sea to Summit Reactor Extreme Mummy Liner

The Sea to Summit Thermolite® Reactor Extreme increases sleeping bag performance by up to 15°C with its super insulating 110g/m² Thermolite® fabric.

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.
