Being cold at night is the number one reason people give up on camping. It’s almost always fixable. Here are nine proven ways to stay warm in a tent.
1. Insulate from the ground first
Most heat is lost into the cold ground, not the air. A sleeping pad with a good R-value matters more than a warmer bag — double up a foam pad under an inflatable one in cold conditions.
2. Match your bag to the temperature
Check the bag’s comfort rating, not its extreme rating, and add a liner for extra warmth. See our sleeping bag picks.
3. Layer smart — but don’t overdo it
Dry base layers and a hat trap heat; too many bulky layers compress the bag’s insulation and make you colder. Keep a dedicated dry set of sleep clothes.
4. Eat and hydrate before bed
Your body needs fuel to generate heat. A warm drink and a small fatty snack before sleeping genuinely helps.
5. The hot-water-bottle trick
Fill a leakproof bottle with hot water and tuck it near your core or feet inside the bag — a classic for a reason.
6. Vent to fight condensation
Crack a vent to let moisture escape; a damp bag is a cold bag.
7. Cover your head and neck
A beanie and a buff dramatically cut heat loss from your head and neck.
8. Warm up before you get in
Do a few jumping jacks to get blood flowing, then climb into the bag already warm rather than waiting to warm a cold bag.
9. Pick a sheltered pitch
Camp out of the wind and off low, cold hollows where cold air pools. A good tent and site do half the work.

Gear that makes these tips easier
- Hot-water bottle trick: the classic bottle is a Nalgene 32oz Wide-Mouth. It’s rated for boiling water and won’t cross-thread in the dark. Don’t use an insulated flask for this, because it keeps the heat inside instead of warming your bag.
- Head and neck: a stretch neck gaiter like the Buff Original EcoStretch doubles as a beanie and blocks the draught at your bag’s opening.
- The right bag: we compared warmth, packed size and value in our best 3-season sleeping bags guide.
- A warmer shelter: see our best backpacking tents guide for tents that pair well with a cold-ground setup.
- Light for late-night faff: our best headlamps for camping beat a phone torch every time.

[…] Even a good blend loses pressure as it gets colder, and because propane burns off first, a half-empty canister runs weaker in the cold. Simple fixes: sleep with the canister in your sleeping bag or keep it in an inside pocket, stand it in a shallow dish of cool (not hot) water while cooking, and use a regulated stove such as the WindMaster or WindBurner if you camp in winter. Never warm a canister over a flame or on a stove. For more on cold nights, see how to stay warm in a tent. […]
