Sea to Summit Reactor Lightweight Schlafsack-Liner

The Reactor Lightweight Liner was optimized for minimal weight and maximum warmth, enhancing your sleeping system with advanced Thermolite® Pro fabric that uses infrared-absorbing ceramic pigments and hollow-core fibers to trap body heat. With up to 4°C additional warmth at minimal pack size, it's ideal for ultralight expeditions. The elastic knit fabric and pre-formed arm cutouts ensure unrestricted freedom of movement. Equipped with HeiQ Fresh for odor control, it's quick-drying, machine-washable, and helps extend your sleeping bag's lifespan by requiring less frequent washing.
