Sea To Summit Reactor Extreme Thermo Mummy
The 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 extras warmth when required. This knit fabric also has serious stretch to it, making the Reactor Extreme the ideal liner for the restless sleeper.
