The Reactor Midweight Liner Regular from Sea to Summit noticeably increases the thermal performance of your sleeping system while ensuring a high level of sleeping comfort. The innovative Thermolite® Pro fabric combines hollow core fibers with infrared-absorbing ceramic pigments that efficiently store body heat, providing up to 6°C of additional thermal performance – while still being compact when packed.

The elastic stretch knit fabric fits comfortably to the body and, in combination with the integrated armholes, allows unrestricted freedom of movement. This makes the liner ideal for use with sleeping bags of any shape and offers a comfortable sleeping experience, whether trekking, on an expedition, or camping.

Thanks to HeiQ Fresh technology, the liner stays fresh longer and reduces unpleasant odors. It is also quick-drying, easy to care for, and machine washable. At the same time, it protects your sleeping bag from dirt and helps to extend its life, as it needs to be washed less often.

• Boosts Sleep System Warmth – Thermolite® Pro uses Far Infrared technology and hollow-core fibres to trap and reflect body heat without extra bulk

• Freedom to Move – Stretch-knit and shaped arm openings allow unrestricted movement, providing natural comfort throughout your sleep

• Technical Shape and Hood – Ergonomic design with a fitted hood delivers optimal warmth and comfort without extra weight or bulk
