Product Information

Additional Information

Product description

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.


From the manufacturer

Sea to Summit stands for a culture of design perfectionists who develop ingenious, functionally beautiful products with an independent, free-thinking Australian attitude. We strive to create equipment that is nimble and light, but serious enough to deliver when called into duty. Gear that works just that little bit better, so you may find yourself inspired to take the less-traveled road more often.

Ingenious. Functional. Reliable. Unconventional. Inspiring.
