Is it comfortable to use dirty sleeping bags? Do you feel uncomfortable?

Try to buy regular manufacturers, and the general comfort can be guaranteed. Regardless of workmanship and materials, it is superior to some inferior sleeping bags, so it is more comfortable. Generally, the width of a single person is about 1 m, and that of a double person is about 1 m 6. Oh, the size is relatively suitable. Sleeping too narrow, I feel wronged and can't stretch out. Too big to be practical, two people can't sleep that big.
