When choosing a sleeping bag, check what seasons it's for, as well as how heavy it is if you're backpacking. Also think about the filling. Natural duck down is very warm, has a longer lifespan and is easier to pack up, while synthetic materials are easier to clean, and they dry quicker and are cheaper.

A Vango Fuse -12
This all-year-round sleeping bag combines natural duck down and a new synthetic fibre. The result is a bag that's warm and weighs 1.5kg. There's a water-resistant finish to protect it from moisture.

B Outwell Campion Lux Double Sleeping Bag
This double sleeping bag – which is suitable for all seasons except winter – is soft and cosy, and there's a handy pocket for essentials, located inside near the top. It also folds up remarkably small, given its size.

C Nordisk Oscar +10
At just 350g, this sleeping bag is remarkably light, and as it's synthetic, it's very easy to maintain. The pack size is just 13×20cm, which makes it ideal for backpacking. It will work perfectly for summer trekking.

D The Big Sleep 250GSM Single Cowl Sleeping
If you want a no-frills, budget sleeping bag that will last more than one summer, opt for this. It's soft, comfy and simple to wash. Give yourself a bit of time to fit it back in the bag, though. Use it for spring, summer and autumn.

E Jack Wolfskin Smoozip +3
We like the extra insulation in this sleeping bag around the areas that tend to feel the cold (head, chest and feet). And the hood is cosy enough to use as a pillow.
