What a sleeping bag liner does
A liner is a thin fabric sleeping bag without fill. In a hut you sleep in it under the blankets, in a hostel on the bed, and inside your own sleeping bag it sits between you and the fill. That keeps your sleeping bag clean so it needs washing less often. Many alpine huts in Europe require one.
