Reactor Midweight Sleeping Bag Liner

A high-performance sleeping bag liner that meaningfully extends your sleep system's warmth and lifespan, the Sea to Summit Reactor Midweight uses Thermolite® Pro fabric with infrared-absorbing ceramic pigments and hollow-core fibres to trap and reflect body heat — adding up to 6°C to your sleep system without meaningful bulk. Stretch-knit fabric and shaped arm openings allow unrestricted movement throughout the night, and a fitted hood delivers targeted warmth without extra weight. HeiQ Fresh odour control keeps it fresh through extended use, and machine washability reduces wear on your sleeping bag by cutting down wash frequency.
