What does it mean that the sleeping bag is suitable for 0 to 10 degrees?

It is the temperature standard for sleeping bags, which can support the use of sleeping bags to rest at the temperature of 0- 10 degrees Celsius.

There are many kinds of sleeping bags on the market now, including many sleeping bags that can be used at different temperatures, and the design types are also different. For example, mummy-style, envelope-style, mixed-style, and small-hat sleeping bags, among which small-hat sleeping bags are also used internationally.

Of course, in extreme weather, when the temperature difference between day and night is large, you can also choose different sleeping bags. The most commonly used fillers are down and chemical fiber cotton. Down is divided into duck meat and goose down. Although goose down has better warmth retention than duck down, both of them are the first choice for cold protection.
