The SunnCamp Deluxe King Size Expression sleeping bag is a timeless classic, and our testers were impressed with its quality and generous proportions


SunnCamp makes a fantastic selection of sleeping bags, in its Junior size, Standard Size, King Size, Super King Size and finally three ranges of Super Deluxe King Size sleeping bags. The largest of the lot are the Expression (the blue, green and white sleeping bag pictured and reviewed here), Jubilee (yellow, orange and red rectangular pattern) and Liberty (green and white checked pattern). All three have the same size, specification and temperature rating, so the fabric design choice is all yours.

We tested the Super Deluxe King Size Expression (product code SB1512) to see if it merited its £40 price tag.

The first thing that impressed our reviewers was that this traditional rectangular sleeping bag is made in a lovely generous size. It measures 203cm (6ft 9 inches) x 92cm (just over 3ft). It weighs 2.85kg and comes with its own compression sack, so that you can pack it down as small as any other traditional sleeping bag can go.  

The polyester fibre filling is an incredible 600 gsm thick and this attractive sleeping bag is designed to keep you comfortable in temperatures from -15°C to +5°C. The design is pleasing to the eye, having a solid blue inner lining, and a geometric blue, green, white and turquoise pattern on the outside. We were impressed by the high quality materials and construction of this sleeping bag. 

It features a two-way zip and if you buy two of these sleeping bags you will be able to sip two together to form a huge double sleeping bag. As it's a rectangular shape with no hood, it should be easy to turn into a double, without the need to choose right and left handed zips, as you would with a tapered mummy style of sleeping bag. 

During our group test of 14 sleeping bags we also reviewed other rectangular shaped sleeping bags. For comparison purposes, check out our reviews of the Vango Serenity, £41, the Kampa Single Layer Citrine, £45, and the Kampa Double Layer Garnet, £35. The Coleman Vail Comfort, £53, is another option, and finally there is another rectangular sleeping bag made by Kampa, the Single Layer Citrine, £43.

Mummy styles of sleeping bags that taper down at the foot are not everyone's cup of tea, but they're extremely warm and practical if you're using them in a confined space. They pack down the smallest of all sleeping bags, perhaps due to their popularity with backpackers, cyclists, explorers and festival goers who need lightweight products that will keep them warm at night. Another great advantage of this type of sleeping bag is that they pack down small, so they'll fit into the caravan lockers easily. 

In our group test we reviewed six mummy sleeping bags. Argos 927/6378 Regatta Single Mummy Sleeping Bag, £20, and the Argos 144/1895 Highlander Sleephuggerz 250gsm Single Cowl Sleeping Bag, £25 - more of a pod than a mummy. We tested the Halfords Urban Escape Tahoe, £20, and the Easy Camp Cosmos sleeping bag, £23. The overall winner of our group test was a bit of a hybrid, combining the best features of mummy sleeping bags with the spaciousness of rectangular bags, all at a low price – it's the Outwell Campion sleeping bag, £25.

The Robens Appalachion 1500, £75, was the most expensive and warmest sleeping bag we reviewed and we thought that its stablemate, the Robens Trailhead 1500 sleeping bag, at £50, merited an even higher rating. 

Finally, we checked out a couple of very unusual snowsuit style sleeping bags. They're not waterproof, but since they have arms and legs, they fit the body as snugly as a hooded onesie. If nothing else, they're guaranteed to raise a smile round the camp fire!

If you just want a good-quality, completely traditional, envelope-style sleeping bag, then you’ll struggle to beat this one. It’s incredibly roomy width-wise, as well as being long; 
in fact, the length rather offsets the lack of any form of hood — it’s unlikely your shoulders will break free during the night because you can snuggle so far down inside. The generous volume of polyester-fibre filling allows very relaxing use down to -15°C, but the compression sack ensures that the packed 
size is as compact as a traditional bag can become.
