Recommended for Winter Survival Kit
When the heating fails in winter, a good sleeping bag is the difference between a miserable, dangerous night and a safe one. It's one of the most reassuring items to have stored away.
Our picks span a dependable all-rounder, a tough bag built for serious cold, and a strong-value option so you can put a warm bag on every bed.
Insulated sleeping bag rated for cold temperatures. Essential for any overnight emergency or planned outdoor stay.
Choose based on the coldest conditions you’ll face. UK three-season: comfort rating of -5°C.
Down: lightest and warmest but useless when wet. Synthetic: heavier but insulates when damp.
For emergency kits, prioritise compact bags that compress to under 5 litres.
Overheating causes sweating, which makes you colder later. Match the bag to conditions.
A warm, packable mummy sleeping bag suited to three-season UK use and cold-night emergencies. A comfortable way to stay warm if the heating fails or you're stranded.
A tough, British-made all-season sleeping bag built to keep you warm through serious cold. The dependable choice when staying warm really matters.
A well-priced synthetic sleeping bag that keeps its warmth even when damp. A sensible, affordable way to make sure everyone has a warm bag.
A roomy two-person bag with a built-in pillow and hood from a trusted British outdoor brand, rated as a 2–3 season bag for milder camping and festivals. It also doubles as a warm, packable layer to keep by the sofa or in the loft for a winter power cut, when keeping two people warm together is more efficient than heating a room. It's bulkier than a solo mummy bag, so treat it as home or car kit rather than something to carry far.
An inexpensive rectangular 3-season bag that's a sensible warmth backup for a car, caravan or home emergency stash rather than serious winter camping. It packs down into an included sack and gives you a warm layer if the heating fails. Rated for milder conditions, so pair it with extra layers or a liner for genuinely cold nights.
A roomy 3-season double bag that two people can share, which makes it a practical bit of warmth to keep at home for a winter power cut as well as for camping. Sharing body heat in one bag is genuinely warmer than two separate ones, and it opens flat as a quilt. It's a budget synthetic bag, so it's bulky and not built for hard mountain use — but for the car, caravan or a cold night indoors it does the job.
A lightweight down-filled mummy sleeping bag that stuffs down small enough to live in a grab bag or the bottom of a rucksack. Down gives a good warmth-to-weight ratio for its packed size, making it a sensible backup for cold nights, power cuts or an unplanned stopover. Keep it dry, as down loses loft when wet, and it will hold its warmth well.
