THERMOLITE® Reactor Extreme is Sea to Summit's warmest seamless sleeping bag liner. Reactor Extreme provides additional warmth to the sleeping bag , and in warm weather or indoors, it can be used as a hygienic sleeping bag by itself.
The hollow fibers of THERMOLITE® fabric act like polar bear fur and, combined with a specially knitted structure, effectively trap warm air . Super soft and surprisingly flexible, the Reactor Extreme uses a heavier version of THERMOLITE® to provide extra warmth for an incredibly comfortable night's sleep.
