Before buying a CHANHONE® Camping Sleeping Bag made in China, ask yourself the following questions? What is the temperature of the environment in which I participate? Do I care about weight? How much do I plan to spend? If you only want to use your sleeping bag in temperatures above zero, choose a cooler one, such as -3 or -5 degrees. If you have a weak cold tolerance, we recommend you also choose a lower temperature index sleeping bag, after all, we can deal with warm than cold is much easier, and much safer.
