Sleeping bags are arguably the most important piece of kit when it comes to staying warm and comfortable while camping. Selecting the right one can make or break your trip, especially during colder months. A poorly chosen sleeping bag will leave you shivering, while a good one will ensure a restful night under the stars.
This buying guide focuses on sleeping bags specifically for the UK's often unpredictable weather. We'll look at factors like fill type, temperature ratings, and intended use to help you find the perfect fit for your camping style.

What to look for
Temperature Ratings – Don't Be Fooled
Temperature ratings on sleeping bags are estimates based on an average sleeper. They assume you'll be wearing thermal layers and that your body heat will play a significant role in keeping you warm. A 'comfort rating' of, say, 0°C might feel genuinely cold if you're a particularly restless sleeper or don't like to overheat. Consider the lowest temperature you realistically expect to encounter when choosing your bag.
Fill Type: Down vs Synthetic
Down sleeping bags are renowned for their warmth-to-weight ratio – they're incredibly light and compressible. However, they lose much of their insulating properties when wet. Synthetic fill retains some warmth even when damp, making it a more practical choice if you anticipate encountering rain or snow. The trade-off is that synthetic bags tend to be bulkier.
Shape Matters: Mummy Bags vs Rectangular
Mummy bags offer the closest fit to your body, minimising heat loss through convection. They're ideal for colder conditions and experienced campers who don't mind a snug fit. Rectangular bags are more spacious and comfortable but sacrifice some warmth due to their looser shape. Consider how much movement you need while sleeping.
Packability – Think About Your Transport
The size of your sleeping bag will greatly impact the ease with which you can transport it. Smaller bags are easier to pack into backpacks, but they often come at the expense of warmth and space. Evaluate how much space you have available in your backpack before making a decision.
Choosing a sleeping bag is about finding the right balance between warmth, weight, and comfort for your specific needs. Don't be swayed by overly aggressive marketing claims – focus on understanding your priorities and selecting a bag that will keep you comfortable whatever the weather.
How we chose
Picks are drawn from the sleeping bags we track on Amazon UK, selected by the rule described under each heading above — not a fixed list of products, so a pick can never quietly point at something out of stock. Where we say a product is well-reviewed, that reflects verified Amazon customer ratings and review counts, not in-house testing we haven't done.
