Your Guide to Choosing the Best Sleeping Bag (Wirecutter Style)
Buying a new sleeping bag can feel overwhelming. There are so many options! We want to help you find the perfect one, just like Wirecutter does. A good sleeping bag keeps you warm and comfortable. It makes your camping trip much better. Here is what you need to know before you buy.
Key Features to Look For
Think about where you will use the bag. This helps you pick the right features.
Temperature Rating
This is the most important feature. The rating tells you the lowest temperature the bag should keep you warm in. Always choose a bag rated for slightly colder weather than you expect. If it says 30°F, it works best around 30 degrees. Never trust the rating completely; always add a layer if it gets really cold.
Shape and Size
- Mummy Bags: These are shaped like a mummy. They are narrow at the feet and snug around the shoulders. They save weight and heat well. They are best for serious backpackers.
- Rectangular Bags: These offer more room to wiggle around. They are heavier and bulkier. They work well for car camping or when space is not an issue.
Weight and Compressibility
If you hike far, every ounce matters. Lighter bags are usually more expensive. A good bag compresses small so it fits easily in your backpack. Look at the “packed size” measurement.
Important Materials Matter
What a sleeping bag is made of changes how warm and light it is.
Insulation Types
- Down (Feathers): Down is very light and compresses small. It is the best insulator for its weight. Down loses its warmth when it gets very wet. Look for a high “fill power” (like 800 fill) for the best performance.
- Synthetic: Synthetic insulation is usually made from polyester. It costs less than down. The big advantage is that it stays warm even when damp. It is bulkier than down, though.
Shell Fabric
The outer fabric needs to be tough. It should resist tearing. Many bags use nylon or polyester. Some feature a DWR (Durable Water Repellent) finish. This helps shed light rain or tent condensation.
Factors That Improve or Reduce Quality
Not all sleeping bags are made equal. Small details make a big difference in quality.
Draft Collars and Hoods
High-quality bags have features that stop cold air from sneaking in. A draft collar is a tube of insulation around your neck. A well-shaped hood cinches tightly around your face. These features greatly improve warmth.
Zipper Quality
A good zipper works smoothly. Look for a “draft tube” running alongside the zipper. This tube is filled with insulation. It stops cold from seeping through the zipper teeth. Cheap zippers snag easily.
Construction
How the insulation is held in place matters. Good bags use “baffles” (internal walls) to keep the insulation evenly spread out. If the insulation shifts, you get cold spots. Poorly constructed bags let the insulation clump up over time.
User Experience and Use Cases
Your experience depends on matching the bag to your activity.
Backpacking vs. Car Camping
If you carry your gear miles into the wilderness (backpacking), you must prioritize low weight and small packed size. You might pay more for high-quality down. If you drive right up to your tent (car camping), warmth and space are more important than weight. A heavier rectangular synthetic bag is fine.
Side Sleepers
If you do not sleep flat on your back, mummy bags might feel too tight. Look for bags labeled as “wide” or “semi-rectangular.” These offer better comfort for side sleepers without sacrificing too much heat.
10 Frequently Asked Questions (FAQ) About Sleeping Bags
Q: What is the difference between the temperature rating and the comfort rating?
A: The temperature rating is the lowest temperature a standard male can survive in. The comfort rating is what most people (especially women) need to stay warm. Always pay attention to the comfort rating if you tend to sleep cold.
Q: How often should I wash my sleeping bag?
A: You should wash your bag infrequently, maybe once a year or less. Over-washing damages the insulation. Spot clean small spills immediately. Use a specialized, mild soap made for outdoor gear.
Q: Can I use a sleeping bag liner?
A: Yes! A liner adds warmth, often 5 to 15 degrees. Liners also keep the inside of your expensive sleeping bag cleaner for longer.
Q: What does “fill power” mean for down bags?
A: Fill power measures the quality and loft (fluffiness) of the down. Higher numbers (like 850) mean the down traps more air for less weight. Higher fill power means a better, warmer bag.
Q: Is synthetic insulation better for wet climates?
A: Generally, yes. Synthetic insulation performs much better than down when it gets damp. If you camp near rivers or in rainy areas, synthetic is a safer bet.
Q: How should I store my sleeping bag when I am not using it?
A: Never store your bag compressed in its stuff sack! Store it loosely in a large mesh bag or a big cloth storage sack. This keeps the insulation lofted and ready to work.
Q: What is a “two-way zipper”?
A: A two-way zipper opens from the bottom as well as the top. This is great for ventilation. You can stick your feet out if you get too warm without fully unzipping the whole bag.
Q: Do I need a vapor barrier liner?
A: Vapor barrier liners stop moisture from your body from reaching the insulation. They can keep down dry in extreme cold but make the inside feel clammy. They are usually only necessary for very specialized, extreme winter trips.
Q: What is the ideal temperature difference between my bag rating and the expected low?
A: Aim for a 10 to 15-degree buffer. If the forecast says 25°F, use a 15°F or 20°F bag. This gives you a safety margin for wind or humidity.
Q: How does loft relate to warmth?
A: Loft is how much the insulation puffs up. The more loft, the more dead air space it traps. Trapped air is what keeps you warm. A higher loft equals a warmer bag, assuming the insulation material is the same quality.
