The Reactor Fleeceweight Liner Regular from Sea to Summit significantly increases the thermal performance of your sleeping system – with minimal additional weight. Thanks to Thermolite® hollow core fibers and warming grid fleece, your body heat is effectively stored and reflected, which can increase the temperature in your sleeping bag by up to 8°C.

The elastic fleece fabric and practical armholes ensure maximum freedom of movement, while snap fasteners allow easy connection to compatible Sea to Summit sleeping bags. At the same time, the liner remains pleasantly easy to care for: it is quick-drying, easy to wash, and equipped with HeiQ Fresh odor control.

An additional advantage: using a liner means your sleeping bag needs to be washed less often. This preserves the loft longer and extends the life of your sleeping bag.

Ideal for anyone who wants more warmth, hygiene, and comfort in their sleeping system.
