Sea to Summit Reactor Lightweight is a technical sleeping bag liner designed for minimal weight and maximum thermal comfort. The advanced Thermolite® Pro material uses hollow fibres and ceramic pigments that absorb infrared radiation, trapping and reflecting body heat. Thanks to this, it can increase the temperature of your sleep system by up to 4 °C without significantly adding bulk or weight to your kit.
The stretch knit fabric and ergonomic cut with a hood ensure natural movement during sleep and comfortable use in any sleeping bag. The liner is quick-drying, easy to care for, and thanks to HeiQ Fresh technology it helps reduce unpleasant odours. Using a liner also protects your sleeping bag from dirt and extends its lifespan.
