The Thermolite Reactor Compact from Sea to Summit ensures extra warmth in particularly cold temperatures. The temperature in the sleeping bag can be increased by up to 11 °C with the inlet.

This is made possible thanks to the use of Thermolite material in two different thicknesses. Due to the mummy cut, the Reactor Plus Compact Liner by Sea To Summit fits closely to the body, which means that no additional air needs to be warmed up, and thus the thermal performance is increased. 

On warm summer nights, the liner can also be used without another sleeping bag. Due to the small pack size, the Reactor Plus Compact Liner by Sea To Summit can be taken anywhere.
