This Sea to Summit Reactor Compact Plus Liner increases sleeping bag performance by up to 20°F (11°C) with dual-weight Thermolite® fabric. The regular 80 g/m² is combined with panels of 110g/m² Thermolite® in the core body and foot bed areas adding extra warmth where most needed. The compact, shorter design of this liner shaves off excess weight while giving maximum warmth for torso and feet.
