The Sea to Summit Reactor Midweight is a technical sleeping bag liner that increases the thermal comfort of your sleep system without significantly increasing weight or bulk.
The advanced Thermolite® Pro fabric with hollow fibres and ceramic pigments absorbs infrared radiation and reflects body heat back towards the body, which can increase your sleeping bag temperature by up to 6 °C. The stretch knit, ergonomic cut and arm openings allow natural movement during sleep and comfortable use in sleeping bags of different shapes.
The liner is quick-drying, easy to care for and, thanks to HeiQ Fresh technology, effectively reduces the build-up of unpleasant odours. Using a liner also protects your sleeping bag from dirt, reduces how often it needs washing and helps preserve its loft and long service life.
