If you're spending time in the outdoors and want your trip to be as enjoyable as possible, you need to make sure you're getting enough sleep to be ready for your activities. That means you need a sleeping bag that's going to give you the best chance of staying warm and comfortable.
A key component is the sleeping bagâs filling. There are two types to choose from: synthetic and down. Synthetic is usually cheaper, washable and dries out more quickly if it gets wet. Duck or goose down, however, is warmer than synthetic filling, and can last longer because itâs better at coping with the repeated compressions of being squashed into your pack. But itâs also more expensive, requires specialist cleaning and is slow to dry out.
What about temperature ranges?
There are some factors to consider before splashing out. First things first â what season do you need the sleeping bag for? Clearly, the most integral purpose of a sleeping bag is that it keeps you cosy and, just like a duvetâs tog rating, different sleeping bags have different temperature ratings.
Some are given in degrees (for example, a limit of -12â means it should keep you warm down to external temperatures of -12â). Others have a more general âseason of useâ rating (for example summer is rated as 1 season, while year-round use is rated as 4 season).
Then thereâs the shape. Do you prefer a simple rectangular shape (usually the cheapest and most basic type) or the snug âmummyâ fit, which is tapered towards the foot to create an insulating layer of warm air? And do you require an inbuilt hood, which keeps you toasty and can double up as a pillow?
To help you make your choice, weâve checked out some of the best sleeping bags on the market.
Best for all-year-round camping
Rab Neutrino 400
The Neutrino is the perfect sleeping bag to own if your outdoor pursuits are on the varied side. Despite a thick, cosy build that will cover you for temperatures all the way down to -7Â°C (20Â°F), it's surprisingly light and packable, which makes it great for adventurous types that need a bit of everything without affecting the amount of kit you can carry.
It's filled with 800FP goose down and covered with a highly effective wind-resistant Pertex Quantum outer. There's also a water repellent coating that helps to ensure water beads and roll from the bag, meaning you stay dry for as long as possible.
Vango Fuse -12
Buy now: Sports Warehouse (UK) | [gbp="159.99"]
This is a great option to take camping at any time of year. Offering the best of both worlds, the sleeping bag is filled with a mixture of hydrophobic down and synthetic insulation fibre, trapping air within the bagâs channels. The result? A sleeping bag that is warm yet lightweight at 1.5kg (3.3lb).
It has a hood with a multi-cord closure, keeping your head and shoulders cosy throughout the night, and thereâs also a handy internal pocket. The zip is fitted with anti-catch piping so it doesnât snag on the lining. The bag also has a water resistant finish to help protect it from damp conditions. This model should keep you comfy right down to -12â (10.4Â°F).
Feathered Friends Swallow UL 20 Sleeping Bag
Buy now: Feathered Friends (US) | $589
Another great year-round option, this model is filled with goose down, and should keep you warm to temperatures as low as -6â (21Â°F), though youâd also be comfortable in it in summer conditions. Unlike some mummy-shaped bags, this one offers a good combination of lightweight warmth with room to sleep thanks to a more relaxed cut than most.
The hood gives you an extra cushion of down around your neck to snuggle up in and it can be cinched tight when temperatures start to drop, but it also opens wide for warm nights. It comes with a storage bag and stuff sack, squashing down into a fairly decent 9 litres.
Best for extreme cold
The North Face Inferno -40C/F Sleeping Bag
If youâre off on a sub-zero adventure, this sleeping bag will keep you toasty in your tent. Designed for temperatures that plunge as low as -40â (-40Â°F), itâs the warmest sleeping bag from The North Face, ideal for expeditions to the coldest places on earth. It has been tried and tested by world-class athletes â so you know youâre getting something that works.
Packed with down, it features a full draft collar and hood cinch cord to keep warm air locked in, while water-resistant fabric on the hood, footbox and back prevents moisture build-up. Itâs also nice and roomy so you can wear extra layers when the mercury really drops, and the central zip makes getting in and out in all your clobber easier.
Best for women
Marmot Women's Angel Fire Sleeping Bag
We love the fact that this womenâs sleeping bag isnât just a pink version of the menâs model. Instead, itâs been specially designed to fit the female body shape optimally, with more insulation in key areas. Itâs also a great option for anyone who gets cold feet at night â it is mummy shaped, but has extra room and insulation at the feet, as well as a heater pocket in the footbox.
Filled with high-quality down that has been treated to resist water and dampness, itâs suitable for most conditions (itâs a 3-season bag). Itâs also super durable, weighs just over 1.1kg (2.4lb) and packs down into a 7.2 litre sack.
Best for couples
Basecamp 200 Double Sleeping Bag
Couples wanting to snuggle up together under canvas can do so in one of these cracking sleeping bags from Mountain Warehouse. Measuring 193cm by 137cm, the Basecamp 200 Double is ideal for two people â or one person looking for extra space.
Itâs not as technical as some of the other sleeping bags on our list, but itâs suitable for relatively warm conditions and should keep you cosy down to around 9â. Insulated with hollow fibre stuffing, it is graded 2/3-season, so will also work for cooler nights in spring and autumn.
Though itâs not as compact as some other super-lightweight models on the market, it still compresses down into a handy drawstring carry case. Available in green with a grey lining, itâs ideal for couples on a summer camping trip.
Best for festivals
Forclaz Trekking Sleeping Bag MT500 15Â°
This is a great budget option that would work well for those just getting into camping or for summer festival-goers. It still features a decent level of technical factors, without breaking the bank. The mummy-style bag should keep you toasty when external temperatures get as low as 0â (32Â°F), and it has a double zip so you can keep ventilated.
You can also twin it with other models from the same range, zipping them together to form a larger, or double, sleeping bag. Filled with polyester, itâs water repellent and can be machine washed and tumble dried. Though itâs not as light or compressible as some other models (weighing 1.6kg/3.5lb and packing into a 15.2 litre sack), it definitely offers great value for money.
Best ultralight option
Sea to Summit Spark Sleeping Bag
If youâre after a sleeping bag thatâs both technical and super compressible, this oneâs hard to beat. Filled with premium goose down, it compresses to just 1.5 litres and weighs only 340g (0.7lb). But despite being small and light, it will still keep you warm on chilly evenings (around 5â/41Â°F).
The mummy design offers efficient insulation, while water-repellent treatment protects the down from external moisture and condensation from the inside of the bag. The half zip with a single slider keeps weight to a minimum while also providing easy access in and out of the bag, and the sewn through baffles around the chest prevent the down from moving around as you sleep.
Best for kids
Decathlon Childrens MH500 0Â° Sleeping Bag
Buy now: Decathlon (UK) | ÂŁ34.99
Cosy and compact, this model is a great option for young campers. Itâs super comfy and will keep kids warm even when temperatures drop to around 0â. Itâs mummy shaped with a two-way zip that's specifically designed for use by kids, and is ideal for children up to 155cm tall (itâs 180cm long by 65cm wide).
The bagâs synthetic filling means that itâs easy to wash â perfect for children â and you can also tumble dry it at a low heat to get it back in action quickly. It weighs 1.2kgs and comes with a stuff bag, packing down to 12 litres. An ideal first time sleeping bag.
Best for hot weather
Traveller 50 Sleeping Bag
When youâre camping in warmer climes, you donât want a sleeping bag that will leave you tossing and turning in the night, feeling hot and bothered. Thankfully there are plenty of options on the market for lighter models suited to summer weather. The 2-season Traveller 50 Sleeping Bag has some great features but wonât break the bank.
The fabric is super durable to prevent rips while also being breathable, and it features a thin, windproof layer. Inside, you'll find inner pockets to keep your valuables safe while you sleep. You should sleep comfortably in mild temperatures, around 11Â°C to 14Â°C.
While this isnât quite technical enough for extreme hot conditions or jungle expeditions, itâs still a great, affordable option for warm weather.
