How to Choose Wild Camping Sleeping Bags?
When you’re planning a camping trip, a good sleeping bag can make or break your experience. You’re sleeping far from home, possibly in unpredictable weather, and often without the luxuries of car camping. That means your sleeping bag isn’t just gear—it’s your bed, your heater, and your barrier against the elements. Choosing the right one is essential for comfort, warmth, and safety.
This guide breaks down everything you need to know when selecting a sleeping bag—from temperature ratings and insulation types to weight and packability.
1. Understand the Temperature Rating
What is a Temperature Rating?
Every sleeping bag is rated for a specific temperature range. These ratings tell you the lowest temperature the bag can handle while still keeping you warm. The key ratings are:
- Comfort: The lowest temperature at which an average sleeper will feel comfortable.
- Limit: The lowest temperature at which a male sleeper will stay warm.
- Extreme: The lowest survival temperature for a female sleeper—not recommended for regular use.
Choosing the Right Temperature Rating
If you’re wild camping in the UK, temperatures vary widely. For summer trips, a comfort rating of 5°C to 10°C may be fine. For spring and autumn, consider bags with comfort ratings of 0°C to 5°C. For winter camping, go for something below -5°C.
Always choose a bag with a slightly lower rating than you think you’ll need. It’s easier to unzip a bag if you’re hot than to warm up if you’re freezing.
2. Know Your Insulation Options
Down vs. Synthetic
Sleeping bags are typically insulated with either down or synthetic fibres, and both have their pros and cons.
Down Insulation:
- Made from duck or goose feathers.
- Excellent warmth-to-weight ratio.
- Compresses very small.
- Long-lasting if cared for properly.
- Con: Loses insulation when wet (unless treated with hydrophobic down).
- Con: More expensive.
Synthetic Insulation:
- Made from polyester fibres.
- Stays warm when damp.
- Dries quickly.
- Con: Heavier and bulkier.
- Con: Doesn’t last as long as down.
For wild camping where weight and weather resistance matter, synthetic bags are reliable and affordable. Down is great for serious backpackers needing top warmth-to-weight performance—just ensure it’s kept dry.
3. Choose the Right Shape
Sleeping bags come in a few shapes, and each one affects comfort, warmth, and pack size.
Mummy Bag:
- Tapered design fits snugly around your body.
- Warmer because there’s less air to heat up.
- Lighter and smaller when packed.
- Best for cold conditions.
Rectangular (Envelope) Bag:
- Offers more room to move.
- Often can unzip into a blanket.
- Best for warm weather or casual campers.
Semi-Rectangular:
- A compromise between room and warmth.
- Good for those who want comfort without too much bulk.
If you’re wild camping in cooler conditions, the mummy shape is usually the best choice. In summer, an envelope bag may be more comfortable, especially if you’re a restless sleeper.
4. Consider Weight and Packability
One of the golden rules of wild camping is to pack light. Your sleeping bag will likely be one of the bulkiest and heaviest items in your pack.
How to Keep Weight Down:
- Choose down insulation for a lighter pack.
- Go for a temperature rating suited to the season—no need for a -10°C bag in July.
- Look for bags with compression sacks to reduce volume.
For most wild campers, a sleeping bag weighing under 1.5kg is a good target. Ultralight options are available under 1kg, but these tend to be expensive and might sacrifice some comfort.
5. Look for Extra Features
These features can make a big difference in performance and ease of use:
- Hood with drawstring: Keeps your head warm and prevents heat loss.
- Draft collar and zipper baffles: Stop cold air sneaking in through zips or neck openings.
- Two-way zippers: Help with ventilation, especially at the feet.
- Left/right zip compatibility: Allows two bags to be zipped together.
- Water-resistant shell: Protects against morning dew or tent condensation.
Small touches like these are worth paying attention to when choosing a bag, especially for longer or more remote trips.
6. Durability and Maintenance
Wild camping often means rougher terrain and unpredictable conditions. Your sleeping bag needs to withstand more than just bedtime.
What to Look For:
- Strong outer fabric: Ripstop nylon or polyester is a good choice.
- Quality zippers: Avoid cheap ones that snag or break.
- Machine washability: Especially important for synthetic bags.
- Stuff sack quality: Reinforced stitching helps prevent tears.
Down bags need special cleaning and storage to stay in good shape. Synthetic bags are lower maintenance, making them a better option for beginners.
7. Budget Considerations
Prices for sleeping bags vary from £20 to over £400. Here’s what to expect:
- Budget (£20–£60): Usually synthetic, heavier, and bulkier. Fine for short trips in good weather.
- Mid-range (£60–£150): Better insulation, lighter materials, more reliable zippers. Suitable for regular wild campers.
- Premium (£150–£400+): Often down-filled, ultralight, and packed with features. Ideal for experienced hikers or colder conditions.
Don’t overspend if you’re just starting out. But don’t go too cheap either—a freezing night in a poor-quality bag can put you off wild camping for good.
8. Try Before You Rely
If possible, try the sleeping bag at home before heading out. Use it during a sleepover or backyard camp. Check how easy it is to pack, how warm it feels, and if it fits your body size.
A bag that’s too tight can feel claustrophobic. One that’s too big may not keep you warm enough. Get the fit right before you’re miles from home.
Conclusion
The best sleeping bag is the one that matches your needs, the conditions you’ll camp in, and your budget. Think carefully about when and where you’ll use it. Look for a temperature rating that suits the season, insulation that works for your packing style, and features that add value without bulk.
Remember: warmth, weight, size, and durability all matter. Do your homework, read user reviews, and don’t be swayed by price alone. With the right sleeping bag, your wild camping adventures will be safer, warmer, and much more enjoyable.
