Best Sleeping Bag for Cold Weather Camping

What sleeping bag do I need for cold weather camping?

Choosing the wrong sleeping bag for cold conditions can turn a great trip into a miserable night. Temperature ratings, fill type, and bag shape all affect how warm you'll stay. Here's what to look for.

What to Check

  • Temperature rating — look for a bag rated at least 10–15°F below the coldest night you expect
  • Fill type — down is lighter and compressible; synthetic stays warm when wet
  • Bag shape — mummy bags retain heat better than rectangular bags
  • Draft collar and hood — these prevent heat from escaping around your neck and head
  • Shell material — look for water-resistant or DWR-treated outer fabric

Tips

  • Layer a sleeping bag liner to add 5–15°F of warmth without buying a new bag
  • Sleep with a hot water bottle at your feet for extra warmth on the coldest nights
  • A well-insulated sleeping pad matters as much as your bag — cold ground steals heat fast
  • Wear a dry base layer to bed; damp clothes reduce your bag's effective temperature rating
