Choosing the Right Sleeping Bag for Camping

Sleeping bags aren’t one-size-fits-all. The best sleeping bag depends on where and when you’re camping, as well as how warm you naturally sleep. Some campers prefer a lightweight bag with more room to move, while others want a snug fit to keep heat in, especially in cooler weather.

If you’re camping mainly in the UK during late spring and summer, a 1–2 season sleeping bag is often a good choice for milder nights. For more flexible use across spring to autumn, a 3-season bag is usually the most popular choice. If you’re camping during colder months or simply want extra insulation, a 4-season sleeping bag is designed for lower temperatures and tougher conditions.

Sleeping Bag Shapes Explained

The shape of a sleeping bag affects both comfort and warmth.

Mummy shaped sleeping bags are designed to follow the natural shape of the body, which helps reduce cold air pockets and retain heat more effectively. They’re a great option if you want to stay warm with a more fitted feel, especially on cooler trips.

Square shaped sleeping bags offer more room and a more relaxed fit. They’re often a popular choice for campsitestays and family camping where comfort and space are the priority.

If you want extra space, XL sleeping bags are ideal for campers who prefer a roomier fit, or for those who don’t like a tight sleeping bag shape.

Adult, Kids and Double Sleeping Bags

Choosing the right type is just as important as choosing the right season rating.

Adult sleeping bags cover a wide range of styles and warmth ratings, from lightweight summer sleeping bags to insulated models for colder trips.

Kids sleeping bags are designed to suit smaller campers and are a better choice than using adult bags that can feel too big, bulky and harder to keep warm in.

Double sleeping bags are ideal for couples or family camping where you want more space.

Sleeping Bag FAQs

How do I choose the right sleeping bag?

The best sleeping bag depends on where and how you’ll be camping. Key things to consider include:

  • Season and conditions – Think about when you’ll use it (summer, 3-season, winter) and the overnight temperatures you’re likely to face.
  • Weight and pack size – If you’re backpacking, a lighter and more compact sleeping bag makes a big difference. For car camping, comfort and size usually matter more than weight.
  • Personal comfort – Some people sleep warmer or colder than others, so it’s worth factoring this in.
  • Sleeping bag shape – Mummy sleeping bags trap heat better and pack smaller, while rectangular sleeping bags give more space to move around but aren’t as efficient in colder conditions.
What do sleeping bag temperature ratings mean?

Comfort rating – The temperature where most people can sleep comfortably. This is usually the most important rating to focus on.

Limit rating – The lowest temperature where a person can sleep without waking from the cold (usually measured using a “standard man” test).

Extreme rating – A survival-only figure showing the lowest temperature someone could endure for a short time (around 6 hours). It’s not a guide for comfortable camping.

Down vs synthetic sleeping bags: which is better?

Both insulation types have their own benefits depending on your camping style:

  • Down sleeping bags are lighter for the warmth they provide and pack down very small, making them popular for backpacking. However, down performs poorly when wet and is usually more expensive.
  • Synthetic sleeping bags are generally cheaper and still insulate when damp, making them a reliable choice for wet or unpredictable weather. They are usually bulkier and heavier than down for the same temperature rating.
