Keeps my bag clean and adds warmth
I'm a side sleeper who runs cold, and this liner adds just enough extra warmth to take the edge off chilly nights. It also means I wash the liner instead of the whole bag. Soft cotton, packs light, machine washable. Great little addition.

Nice for hostels and hotels
Bought this mainly as a travel sleep sack for questionable hostel bedding and it's done the job well. Cotton breathes better than silk for me and it folds down reasonably small. A bit heavier than silk options but far cheaper.

Soft and simple
Feels great against skin, washes well. Exactly what I needed for summer nights in the bag-less mode.
