How to Stay Warm in a Sleeping Bag?

When you’re out in the wilderness, staying warm is essential for survival. Knowing how to stay warm in your sleeping bag is key for any camping or backpacking trip — here are some tips for ensuring that you stay comfortable and safe during your outdoor adventures.

Use an insulated mattress pad

Dress Right

One of the most important things to do before settling into your sleeping bag is to dress appropriately. Wear layers of clothing such as wool socks, fleece pants and a lightweight jacket so you have additional insulation and warmth when needed.

Pre-Heat Your Bag

You can pre-heat your sleeping bag by using chemical packets such as hand-warmers, filling up a hot water bottle, or even using body heat from another person! This will help raise the temperature inside the bag so you don’t have to wait until it reaches its maximum capacity before getting warm.

Avoid Condensation Inside the Bag  

If there is condensation inside your sleeping bag, this can sap away your body heat — leaving you feeling cold and wet! Make sure to use a breathable liner or layer of fabric between yourself and the sleeping bag, and keep all damp clothes or gear outside of the tent.

Use an Insulated Mattress Pad

Another way to avoid losing body heat is by placing an insulated mattress pad between yourself and the ground — this will act as an extra layer of insulation and ensure that warmth does not escape through the colder ground below.

Dos and Don'ts for Staying Warm in a Sleeping Bag

Staying warm while camping or backpacking is essential for a successful outdoor adventure. Here are some dos and don’ts to keep in mind when trying to stay warm in your sleeping bag:


  • Dress appropriately with layers of wool, fleece and lightweight jackets.

  • Pre-heat your bag with chemical packets, a hot water bottle, or body heat from another person.

  • Use an insulated mattress pad between yourself and the ground to avoid losing body heat.

  • Bring extra blankets, hats and gloves in case of cold weather.
