Sleeping bag FAQs

What type of sleeping bag is warmest?
There's a very closely related question to this, which is: 'What sleeping bag shape is the most efficient?' The straightforward answer to both is a mummy-shaped sleeping bag insulated with high loft down.
Down offers the best warmth-to-weight ratio for insulating gear and garments. And mummy-shaped sleeping bags have a tapered, more confined fit than a rectangular-shaped sleeping bag and is, therefore, easier to keep warm. Check out our in-depth guide to sleeping bags for more information.
What is the difference between cheap and expensive sleeping bags?
The key factors that influence price are the type of insulation, sustainability, and whether the sleeping bag is aimed at regular camping or more demanding trekking or hiking.
For example, the cheapest type of sleeping bag you'll find is a lightly insulated summer option with synthetic fill aimed at weekend family camping. It doesn't need to be especially light or compact; it probably doesn't have any sustainability credentials to shout about.
At the other end of the spectrum, you have the warmest sleeping bags for winter expeditions in the mountains. These use tough fabrics and very high-quality down insulation, both treated to be hydrophobic. If the brand is sustainable, it will have used recycled and PFC-free materials and have high labour standards so that the people who make their gear are paid properly and respected.
Key features to look for in a sleeping bag

Sustainability: It's vital you take sustainability into account. No one will force you, but it's an important aspect to consider. A sustainable sleeping bag positively affects not only the impact of its production but also the longevity of the sleeping bag and the use you get from it.
Temperature rating: This is a rough guide to the temperature range a sleeping bag is designed for. A sleeping bag normally has three figures in a temperature rating: Comfort, Limit, and Extreme. Comfort is where the sleeping bag is comfortable for an 'average' adult female; Limit is comfortable for an 'average' adult male; Extreme is a survivable temperature, but you run the risk of hyperthermia.
Insulation type: Down and synthetic fill are the two types of insulation used in sleeping bags. Down is lightweight, warm, and durable. Synthetic fill is cheaper and better in damp conditions but is heavier.
Weight and packed size: How light and compact a sleeping bag only matters for backpacking and hiking trips where rucksack space is at a premium. For family campsite camping accessed by car, it's not so important. Hikers need to think about a balance of low weight and small size against volume of insulation and warmth.
Material: Nylon is commonly used to make hiking sleeping bags because it's lightweight and strong. Polyester is more common for camping sleeping bags because it's cheaper and a bit softer to touch. Look at the fabric's denier, and this will give you an indication of material strength. High denier means a denser, tougher fabric; lower denier means lighter but more delicate.
Shape: Mummy-shaped sleeping bags offer the best efficiency because of the tapered fit. But they can feel restrictive, and you may prefer a more rectangular shape. Semi-rectangular options exist as a middle ground. And don't forget about women's specific sleeping bags that have more insulation around the feet and hips.
Extra features: Zip length is one to consider. Full-length zips make the sleeping bag easy to get in and out of but compromise weight and warmth somewhat. Shorter zips are the converse of this. Draft tubes and collars boost a sleeping bag's insulating efficiency like they do in your house. If you're opting for a down sleeping bag, also consider whether a hydrophobic down treatment is something you want.
How we tested
Our testing of sleeping bags involves a lot of nights out in the hills and mountains. It's time-consuming but we aren't complaining.
We test sleeping bags in the conditions for which they are intended. So, for lightweight summer sleeping bags, we see if they perform in milder conditions. Three-season sleeping bags are tested across multiple seasons. Winter sleeping bags are tested in harsh winter conditions. If a sleeping bag claims to perform in damp conditions, we put that to the test. Our heavily experienced gear testers consider not only outright performance but other important aspects such as build quality and sustainability.
Annually, we create the ultimate shortlist of the very best gear in our Gear of the Year Awards.
