Using super-insulating 110g/m² THERMOLITE®, our Reactor Extreme is our warmest knit sleeping bag liner. The hollow core fibre threads work just like the hollow fur of a polar bear in that they trap heat effectively. When the mercury drops, you’ll appreciate the mummy shape and drawcord hood cinched down for extra warmth with its mini cord lock. The knit fabric also has serious stretch to it, making it an ideal liner for the restless sleeper.
