The best sleeping bags for camping, festivals and hiking, tried and tested

Mammut really meant it when it named this bag “perform” – this design is our top pick for trekkers who need reliable warmth and comfort in tough conditions. Rated for comfort down to -7C, this is a seriously cosy bag – animal down instantly traps in body heat and is super warm, without adding much bulk or weight, so it’s ideal for backpacking. An adjustable hood and slim foot box further trap in the heat.

While the perform is one of the most expensive options in our round-up, it’s well worth the spend if you sleep outdoors year-round. We also like the included sleeping bag mask and earplugs – thoughtful little extras for getting a good night’s kip.

A decent three-season sleeping bag for £50? Meet the microlite 1400, which ticks all the boxes for a reliable sleeping bag for a very pocket-friendly price. This mummy-shaped bag uses synthetic insulation plus a close-fitting hood to trap in heat, and has a comfort rating suitable for temperatures as low as 0C, which should suit milder winter camps in Britain.

It’s a real bargain for campers headed to wilder parts, although, this isn’t the lightest or most compact adventure bag, so, it won’t suit campers who are into packing super light. Left- and right-handed zip versions and two lengths are available.

Bringing the littluns camping? A comfort rating of 5C makes this cute sleeping bag a decent choice for keeping kids cosy from spring through to autumn – our small tester was very comfy in May.

Mini campers can pick from turtles, unicorns or dinosaurs parading across their bag and the rectangular shape is roomy and comfortable. For family camps and sleepovers, you can’t go wrong at this price.

Fancy sharing with your favourite camper this summer? Our pick of the double sleeping bags on offer is this snuggly two-person option from Outwell. A cotton inner liner feels as cosy as your duvet from home; there’s plenty of space for two, and we love the built-in pillows, which are handy in case you forget to bring yours. Where this comforting and cosy bag really differs from other double models we’ve tested is in warmth – it’s rated for comfort down to 5C and its limit is -1C, so it’ll be suitable for three seasons. This bag is heavy and bulky when rolled up but, if you’ve got the space to store it, it’s worth the spend.

Seventy-four per cent of us like to sleep on our sides – if you’re in the majority, choose a bag with a customisable left or right zipper to suit what side you like to sleep on, such as the Robens gully. Weighing in at less than a kilo, this is a light and airy bag that’s ideal for bringing along on fast-paced summer adventures and for use in bothies and campervans.

We like that Robens has gone for the best of both worlds, with a mix of down and synthetic fill for lightweight warmth. While this is a mummy-style bag, it’s not restrictive, and you can also zip together two Robens bags if you like your fellow camper and fancy sharing. A quality choice for summer weather.

We’d love to see all outdoors brands use environmentally friendly materials as standard but, for now, Vango is leading the pack with the apex 2, which has a lining made from recycled fishing nets, and uses high-performing, recycled synthetic EcoLoft insulated filling to keep you cosy down to -6C, which should suit use in all seasons in Britain. The lining also reflects body heat back and makes you warm up fast on chilly nights. During testing, we found the mummy shape to be the perfect balance – slim enough to trap in heat, wide enough to get comfortable.

If you’re a fair-weather camper and only plan to use your sleeping bag during balmy summer weather, we reckon Vango’s kanto XL could be your perfect companion. This extra-large single bag is delightfully roomy and duvet-like to sleep in, and the generous size is ideal for tall or plus-size campers. The bag is easy to pack into its stuff sack and is soft against the skin, while the hood traps in warmth nicely. This bag is perfect for casual camps and camping during the summer months.

The priciest sleeping bag in our round-up is also one of the very best we tested. If you’re into lightweight fastpacking or bikepacking adventures, you’re probably on the hunt for a design that won’t add weight or bulk to your kit, and, at 594g, the hyperion is impressively small (it packs down to the height of a large water bottle) and easy to pack. Unfurl it from its compression pack and you’ve got a delightfully soft and cosy bag, stuffed with animal down that’s been treated with Nikwax, so it’s water-repellent. The ergonomic shape of the hyperion traps in heat brilliantly, and we found it kept us warm and comfy on frosty autumn nights. A great quality choice for adventurous camping.

If you tend to toss and turn during the night, you’re likely to find slimmer sleeping bags on the restrictive side. However, the softie expansion is designed to give you plenty of room to get comfy. A clever elasticated expander panel means you can zip up snugly on a cold night but add extra space when needed, and that extra room also allows more air flow during hot nights. With a comfort rating of -15C, the softie will keep you warm in all seasons, and features a few handy extra features, including a built-in LED torch, an adjustable foot length and internal pockets. This is one of the heavier bags we tested, so it’s better suited for car camping rather than backpacking trips.

This bright lime-green wonder is a great all-rounder of a sleeping bag that will work for camping holidays and wilder adventures alike. At 1.1kg, the ascent ACII is light and packable enough to bring along in your rucksack, but still offers a decent comfort temperature of -10C, thanks to its down filling, so you can get away with using it year-round.

A multiple-zip design makes it easy to add ventilation on hot nights, and you can fold down the top of the bag, like a quilt, for added comfort.

Available in unisex or women’s-specific lengths, this is a good does-it-all bit of kit.

No need to unzip yourself from your comfortingly warm sleeping bag on a chilly morning – Voited’s clever new design is an all-in-one sleeping bag that can double up as a cosy coat if you simply unzip the foot box.

Warm primaloft insulation is a good synthetic (and vegan) alternative to animal down, and has a comfort limit of 11C, making this bag-with-arms a good choice for summer festivals and family holidays.

Of course, you get a bonus winter coat in the bargain, which you can sport during dog walks, the school run and more.

If you tend to get cold at night, go for a down-filled sleeping bag – they always deliver on comfort and warmth. Kelty’s three-season cosmic ultra is a well-priced pick, stuffed with insulating DriDrown. This is Kelty’s own-brand technology, which is designed to keep you warm without excess weight, but will still work well if it gets wet from rain or humidity.

The cosmic ultra is pleasingly squishy and soft to sleep in, and will fit into a bigger backpack – perfect for weekends outdoors and more casual wild camping, as well as for traditional camping trips. There’s a good reason why this bag is a bestseller.

If you want to protect the planet with your sleeping bag purchase, Sierra Designs’s night cap 20 is made from recycled synthetic insulation sourced from plastic water bottles. It also features a recycled fabric outer material, so it’s a more eco-conscious choice than many designs.

We like the internal sleeping mat sleeve, so you can pop your camping mat inside to keep it in place if you’re a restless sleeper, and the foot vent, which makes it easy to cool off on hot nights.

This is a clever “zipless” design with an innovative duvet-style cover that gives you that tucked-in feeling of your bed at home.

Keeping you comfortable in temperatures down to -17C (or, in an extreme temperature of -50C, keeping you alive, if not that comfortable), this sleeping bag will suit most winter conditions in the UK. It’s also very affordable, compared with some other winter bags aimed at women.

The musca’s shape is a mummy style, without being too restrictive, so heat is trapped in without making you feel like you’re kipping in a coffin.

We wish all bags had a handy internal pillow pocket like the musca’s – just pop in your travel pillow for a comfier night’s sleep.

On warm summer hiking adventures or when backpacking and camping abroad, you don’t want to be weighed down with a heavy, bulky bag – so, swap your warm winter equipment for Jack Wolfskin’s athmos.

Lightweight at just 650g and packable in a rucksack or a bike pannier, but with plenty of pleasingly soft down to keep you cosy, this is a good go-anywhere summer sleeping bag you could take on adventures in your carry-on. It also gets bonus points for being made mostly with recycled materials.
