Sleeping bag liners are lightweight cloth sacks usually fitted inside sleeping bags to provide extra comfort, insulation, and help keep the sleeping bag clean. A thin liner may feel softer against the sleeper's skin, add 5 °F warmth to the bag (not pad), and be easily washed after use (unlike the thicker sleeping bag).
