10 best sleeping bags for keeping cosy during all seasons

Sleeping under canvas in the great outdoors isn’t for everyone, but the right kit can make camping much more fun. Quality sleep, snuggled up in a warm and cosy bed is a total game-changer when you’re away, so we’ve investigated the comfiest sleeping bags to invest in this year.

Camping can be a wonderful way to spend time together as a family. However, the UK weather is one of the biggest challenges to happy camping. Summer rain, changeable conditions and chilly nights, even after warm days, can lead to us underestimating how cold it can get in a tent at night. That said, if you’re a person that runs hot, being bundled up in a mummy sleeping bag will make you just as uncomfortable as the friend shivering next to you. 

Warmth rating, ventilation and a comfortable shape are all essential features to be considered. Prices can vary hugely; a technical sleeping bag suitable for wild camping in the mountains can cost hundreds of pounds. That might be overkill for family camping in the Lake District; however, if you’re under canvas every weekend and feel the cold, investing in a high-quality sleeping bag that guarantees a settled night of sleep is important. 

With the help of recommendations vetted by users on our forums, outdoor equipment best buy lists and genuine consumer reviews, we’ve extensively researched and chosen the top practical, warm and packable sleep solutions for your next camping trip. They’ll even come in handy as extra bedding around the house if you have guests over. 

Here are the best sleeping bags to keep you cosy in 2022.

1. Best overall sleeping bag: Vango Nitestar 250S 3-Season Sleeping Bag

Vango sleeping bag

Price: £36 | Buy now from Go Outdoors

“I've got a Vango Nitestar Sleeping Bag, and I love it!!” (Tried and tested by Mumsnet user Blueuggboots)

The Vango Nitestar will provide a warm night of sleep, even on chilly nights. The mummy shape allows your body to be encased in the soft, breathable fabric while keeping chilly drafts out. 

We loved the practical details, such as hanging loops for quick airing and drying, plus the internal pocket, which allows you to keep your valuables safe and close. 

The zip is insulated and, thanks to the nifty anti-catch device, it’s consistently easy to pull up and down. The baffles are well spaced so that the filling stays in one place, and the compression stuff sack makes the Nitestar quick to pack away in the morning. 

It's the ideal choice if you have a teenager partaking in Duke of Edinburgh or for a summer family holiday, but if you're a wild camper you'll want something more suited to year-round camping. 

Pros

  • Hanging loops for easy airing and drying
  • Internal pocket
  • Anti-catch zip

Cons

  • Large pack size

Key specs

  • Weight: 1.65kg
  • Shape: Mummy
  • Filling: Insulite Alpha
  • Temperature: Comfort 2°C, Limit -4°C, Extreme -21°C

2. Best budget sleeping bag: Hi-Gear Divine Single Sleeping Bag

Hi-Gear sleeping bag

Price: £30 | Buy now from Go Outdoors

“We've had the HiGear 3-season bags from Go Outdoors. They were probably £20/30 each and we've never been cold even in early/late season.” (Vetted by Mumsnet user RomaineCalm)

The Hi-Gear Divine sleeping bag is a double-layered synthetic bag that feels soft on the skin and provides enough warmth for cooler nights in the UK but could be used on warmer nights with the zip undone. 

Compared to similar synthetic bags, this is a light bag, so it would be ok for wild camping and camping holidays on a site, but bear in mind it’s not the most compact for carrying. In addition, the square shape is a good option for people who feel restricted by mummy-style bags. 

We were impressed with the price, and if you’re kitting out an entire family, this bag would be perfect for spring and summer camping trips away without breaking the bank. 

Pros

  • Great value 
  • Soft fabric
  • Lightweight

Cons

  • Not compact when packed

Key specs

  • Weight: 1.6kg
  • Shape: Square
  • Filling: Synthetic
  • Temperature: Comfort 0°C, Limit -5°C

3. Best three-season sleeping bag: Kelty Cosmic 20 Three Season Sleeping Bag

Price: £130 | Buy now from Amazon

A three-season sleeping bag is a perfect weight for most family camping trips in the UK, and the Kelty Cosmic Ultra is a fantastic option. It’s a technical bag that isn’t cheap, but it's well worth the investment if you’re a regular under canvas. 

It’s light, packs small and has a clever baffle construction that keeps the bag fluffy and the sleep toasty warm. The water-resistant coating on the outer fabric is practical too. 

We loved that the Kelty is available in various shapes and sizes to suit different body types and heights. The women's option's wider hips and narrow shoulders make it less restrictive but resistant to drafts. 

Pros

  • Available in different shapes and lengths
  • Soft and silky inner material
  • Lightweight

Cons

  • Smells strange when first opened but it fades 

Key specs

  • Weight: 1.27kg
  • Shape: Mummy
  • Filling: Down
  • Temperature (comfort, limit, extreme): Comfort -1°C, Limit -7°C

4. Best four-season sleeping bag: Fit Nation Viking Trek Sleeping Bag

Fit Nation sleeping bag

Price: £29.99 | Buy now from Amazon

The Fit Nation Viking Trek Sleeping Bag is another excellent budget sleeping bag that allows you to set up your family for years of camping at a minimal cost. It’s very warm, with a snuggly but roomy barrel shape. 

We were delighted with the breathable and sweat-wicking fabric, which is perfect for if you run hot. The anti-catch zipper is fab too; it makes getting in and out, especially for the dreaded loo trip at night, so much less of a faff. 

 This synthetic fill bag is quite bulky, but the waterproof compression sack means it can be attached to the outside of a rucksack if you need to hike into your campsite. 

 We thought the price made this a great option for newbies and holidaymakers, rather than avid wild campers.

 Pros

  • Lightweight 
  • Internal stash pocket 
  • Water resistant 

Cons

  • Long length could be uncomfortable for shorter people
  • Some found it ripped easily 
  • Comfort temperature lower than some other bags

Key specs

  • Weight: 1.44kg
  • Shape: Barrel 
  • Filling: Synthetic
  • Temperature: Comfort 8°C; Limit 3°C; Extreme -11°C

5. Best wide sleeping bags for camping: Sleeping Pod Sleeping Bag

Sleeping Pod

Price: £35 | Buy now from Go Outdoors 

“Love LOVE our snooze pods and they are brilliant for a good night’s sleep.” (Recommended by Mumsnet user fantastaballs)

The Sleeping Pod is an innovative sleeping bag that combines warmth with freedom of movement. If you like to sleep star-shaped or feel claustrophobic in standard sleeping bags, the oval shape of the pod is ideal.

The fluffy synthetic filling traps air, keeps you warm, and is also very efficient at handling moisture. The insulated zips and design of the head and shoulders keep drafts out in the cold and lets air in when it’s warm. 

We thought the internal pocket for phones and torches is a valuable feature. In addition, it’s quick and easy to pull out and pack away the bag into the compression sack included.

Pros

  • Great for fidgety sleepers
  • Good option for kids
  • Double layered fabric for extra warmth

Cons

  • Large pack size
  • Two season, so better suited to summer trips 

Key specs

  • Weight: 1.7 kg
  • Shape: Oval
  • Filling: Synthetic
  • Temperature: Comfort 5°C, Extreme 0°C

6. Best kid’s sleeping bag: Youmako Kids’ Sleeping Bag

Sleeping bag for children

Price: £24.99 | Buy now from Amazon

The Youmako range of kid's sleeping bags comes in lots of funky colours, perfect for working out which one belongs to which child. With a colour coordinated compression sack included, it would make a great gift too. 

They have been created for cooler summer weather rather than freezing nights and are made from durable, waterproof outer fabric. The double-layered synthetic insulation is kept in place with small, warmth-boosting baffles, creating a fun pattern on the outside of the bag. 

We adored the rare machine washability of these sleeping bags. It makes them perfect for messy toddlers and camping in a muddy field. The bottom zipper is also an excellent feature for fidgety little ones who dislike feeling enclosed. 

Pros

  • Fantastic range of colours 
  • Machine washable 
  • Unzips to make a blanket 

Cons

  • Not suitable for cold nights

Key specs

  • Weight: 1.59 kg
  • Shape: Square 
  • Filling: Synthetic 
  • Temperature: Comfort 1–10°C

7. Best double sleeping bag: Coleman Hampton Three Season Double Sleeping Bag

Coleman sleeping bag

Price: £99.99 | Buy now from Amazon 

“I got myself a double sleeping bag (Amazon - Coleman Hampton three seasons). It was very pricey but definitely worth every penny!! I used it on my own and can starfish on the air bed in it!” (Vetted by Mumsnet user undomesticgodde55)

Snuggling up together will keep you warm and can be fun or romantic, depending on the nature of your camping trip. This Coleman Double Sleeping Bag is roomy, beautifully insulated and has extra padding for softness and comfort around the face. 

This bag's 100% cotton fabric is fantastic for people who don’t like artificial materials. It can even be machine washed in a large capacity machine or at the launderette. 

This huge sleeping bag would also make a fantastic bed for sleepovers, as a blanket for winter afternoons enjoying the garden or even cold-weather picnics and beach days. 

Pros

  • Soft padding around the face and neck 
  • Insulated zipper
  • Natural fabric - 100% cotton 

Cons

  • Heavy 
  • Bulky

Key specs

  • Weight: 4.55kg
  • Shape: Square 
  • Filling: Synthetic 
  • Temperature: Comfort +5°C, Extreme -15°C

8. Best down sleeping bag: Rab Ascent 700 Sleeping Bag

Rab sleeping bag

Price: £216 | Buy now from Cotswold Outdoor

Down is the warmest and lightest material for sleeping bag filling. It’s fluffy, so it feels soft and luxurious and packs down small. The Rab Ascent is a technical bag with lots of clever features, so it’s more expensive than usual, but we think it’s worth it. 

The ethically-sourced hydrophobic duck down in the Ascent is effective when wet, and it dries much quicker too. It also has a slightly wider than standard mummy-style design, a big foot box and adjustability at the head and neck for a draft-free but spacious fit. 

Innovative and useful additions included an internal pocket, a glow-in-the-dark zipper and a supportive neck collar. 

Pros

  • Great after-sales service from Rab 
  • Wide mummy fit 
  • Water resistant

Cons

  • Pricey

Key specs

  • Weight: 1.29 kg
  • Shape: Mummy
  • Filling: Hydrophobic down
  • Temperature: Comfort -2°C, Extreme -27°C

9. Best synthetic sleeping bag: Jack Wolfskin Smoozip Sleeping Bag

Jack Wolfskin

Price: £110 | Buy now from Jack Wolfskin

Sleeping bags with a synthetic filling are warmer in wet weather and are usually more robust thanks to the durable fabrics. The Jack Wolfskin Smoozip is a great example, and it’s at a lower cost than some of the more high-end sleeping bags. This would be a fab bag for Duke of Edinburgh schemes. 

We were impressed with the skin-friendly lining, which offers valuable, odour-fighting features for long expeditions. In addition, the unusual, ergonomic zip design is fantastic for people who hate faffing with and accidentally sleeping on a side zip. 

The Smoozip isn’t a fluffy bag, which some people prefer, especially in warmer weather. However, it does have extra padding where there may be drafts, or extra softness is needed. 

Pros

  • Skin-friendly lining
  • Clever zip design 
  • Soft lining around face and neck

Cons

  • Bulky

Key specs

  • Weight: 0.87 kg
  • Shape: Barrel 
  • Filling: Synthetic
  • Temperature: Comfort 1°C, Limit -5°C, Extreme - 22 °C

10. Best lightweight sleeping bag: Therm-A-Rest Hyperion Sleeping Bag

Thern

Price: £369.51 | Buy now from Amazon

The Thermarest Hyperion is a super lightweight bag for adventurous families who hike in their gear to camp. 

We were impressed with the pack size. It will take up very little room in your rucksack while still being fluffy enough to trap lots of warming air. 

The responsibly produced down has been given a Nik Wax coating, which means that it will keep you warm when it’s damp and dry quickly, unlike many down sleeping bags. The RipStop outer fabric is durable too, perfect if you occasionally like to bivvy on rough ground. 

The hefty price tag is worth it for its thermal and lightweight features if you’re an outdoors enthusiast, but if you’re more of a casual camper, you’d be better with a more affordable option. 

Pros

  • Small pack size that can be attached to the outside of a rucksack
  • Very light
  • Water-resistant 

Cons

  • Expensive

Key specs

  • Weight: 0.45 kg
  • Shape: Mummy
  • Filling: Hydrophobic down 
  • Temperature: Not specified

How to choose the best sleeping bag 

A sleeping bag can set you back anywhere between £30 to £300. Here’s a few points to consider before you pick the one for you:

  • Temperature rating: Sleeping bags will have three figures to consider. Remember though, they are a rough guide as we are all different. Comfort relates to the outside temperature at which ‘most women’ will sleep comfortably when in the bag. Limit relates to ‘most men’, and Extreme is a more severe measurement: the temperature at which most women can survive in the bag for six hours without getting hypothermia. If you’re more of a casual camper, focus on the comfort rating when choosing - this will tell you the temperature the bag should be effective at for a whole night. 
  • Season: This is another way to describe the temperature rating. The higher the season, the warmer the bag. One season is suitable for warm nights and hostels, and two season is for late spring and early autumn. Three and four season are the most useful for family camping throughout the year as they can be opened for ventilation on warmer nights. 4+ and 5 season are designed for mountaineering expeditions, but some people who really feel cold love them too.
  • Zips: Some sleeping bags have left and right-hand zip options. It’s easy to overlook this small detail, but it can be really tricky to zip up a bag when it’s on the wrong side. If you’re right-handed, go for the left zips and if you’re left-handed, choose a right zip. 
  • Packability: The size and weight of your sleeping bag won’t matter if you have a big car and are driving to the campsite. However, if you’re a big family, have a small car or enjoy wild camping, a lightweight and compact shape will be necessary. Most bags come with a compression bag or stuff sack that will reduce the size of your bag dramatically. Our tip for quick and easy repacking? Stuff it in, don’t roll or fold.  
  • Baffles: These are the pockets of filling which are separated by stitching. They ensure that the filling doesn’t clump together, causing cold spots. If warmth is key to your comfort, look for sleeping bags that have small, narrow baffles. 
  • Gender-specific fit: Some sleeping bags are available in men’s and women’s fit. This generally means that the hip and chest area will be roomier, the shoulders narrower for women, and the men’s bag will be broader and longer. 
  • Length: Shorter people may find they shuffle down a ‘standard’ sleeping bag, and taller individuals will feel restricted. Look for brands that offer different lengths of bags. If you’re buying for older children, a smaller adult size may last longer than a sleeping bag designed for children.   

What are the different types of sleeping bags?

Most sleeping bags are ‘mummy-style,’ which means they taper to a narrow profile at the feet and have a close-fitting hood. This increases warmth and takes up less space in the pack and tent.

Some people, especially those who move around a lot in their sleep, find them restrictive. If this is you, look for square or barrel-shaped sleeping bags with the same width from head to foot. 

Pod sleeping bags, with cosy hoods and an oval body, are becoming increasingly popular too. 

What's the best fill for a sleeping bag?

The fill of your sleeping bag will dictate the warmth and the weight, and you can choose between synthetic fabrics or down. Down is the finest feathers from a duck or goose, this can be an ethical issue for some, but the vast majority of manufacturers do source the down responsibly. 

Down is the warmest and lightest option, and it is easy to squeeze down into a stuff sack. However, if down gets wet, it loses its insulating ability and is tricky to dry. Technical sleeping bags often contain hydrophobic down that has been treated to be water-resistant, but these can be expensive. 

Fill power relates to the fluffiness of the down and the amount of warm air it will trap. The higher the number, the higher quality of the down and the lighter the bag will be to carry. 

Synthetic sleeping bags have more weight and are bulky, but they are less costly and will still keep you warm when it’s wet. In addition, innovations in fabric technology mean that more expensive synthetic bags are becoming lighter and warmer. 

What is the best sleeping bag?

We chose the Vango Nitestar for the warmth it delivers, it’s relative lightness and packability and the great price. For a family who loves camping, this is an excellent choice for adults and older kids alike.
