Here you have my selection of the best cotton sleeping bags for adults, all with an impressive temperature rating, incredibly comfortable and very affordable.
What I mean by cotton sleeping bags?
When you speak about sleeping bag materials, you normally have in mind its external shell, then inner liner, and finally its fill or insulation. So the sleeping bags in the list are with the following combinations:
- Cotton used only for the liner.
- Cotton used for both liner and shell.
- Cotton used for liner & insulation.
Are cotton sleeping bags good?
Having flannel as a liner is the most pleasant option. This is a breathable material but note that it absorbs moisture and it may be difficult to dry it quickly.
The same objection holds for the cotton shell and insulation. So you will see many cotton bags in the group of those for very cold weather but note that after a long time of use, such a bag can accumulate moisture, and this may affect its thermal efficiency. Quite generally, it is best to avoid vet conditions with such bags.
If you still go for cotton, the best option would be to have only the cotton liner and the rest to be synthetic.

How to choose
All these cotton sleeping bags for adults are large and most of them are also very warm. They are very comfortable, but quite bulky and heavy. There are substantial differences regarding their weight and packed size related to the combination of materials used in their construction. So check the numbers carefully.
Note also that there are differences in their design, and I think the hood is the most important one. A hood adds a lot to overall performance and warmth, so if you expect really cold weather, go for a hooded bag.
