Sleeping bags are available with down or synthetic fiber filling.

If there is a large difference between the comfortable temperature and the air temperature, it may be too cold or too hot, so make sure to check the temperature at the campsite and the comfortable temperature of the sleeping bag before purchasing.

Along with the comfortable temperature, you should also check the type of sleeping bag.
