To sleep well while camping, you need the best sleeping bag for the situation, one that will keep you cozy in low nighttime temperatures under the stars. Down sleeping bags are especially comfortable and insulating, so here are some we recommend for your next camping trip.

Buying a Down Sleeping Bag

Here are some things to consider before you buy:

  • Temperature: Consider choosing a sleeping bag with a lower temperature rating than the coldest nighttime temperature you expect, especially if it’s in the colder months, so you can stay nice and warm.
  • Shape: Sleeping bags that taper closer to the body will usually keep you warmer, while rectangular ones will allow you more wiggle room to stretch and sleep comfortably.
  • Interior Materials: Consider if you prefer a sleeping bag with goose down or a synthetic fiber option.
