Question: Can Down Sleeping Bags be Washed
Answer: Down sleeping bags could be washed, but it needs more time and careful attention. It is pretty costly to have them professionally cleaned, but you could also do it yourself.
Yes, down is warmer than synthetic. Down is the soft, fluffy, and lofty stuff under the feathers.
