Your Guide to Choosing a -20 Sleeping Bag
A -20 sleeping bag is a serious piece of gear. It’s built for cold nights, keeping you warm when the temperature drops way below freezing. If you’re planning winter camping, mountaineering, or just need a reliable bag for chilly weather, this guide will help you pick the right one.
1. Key Features to Look For
Temperature Rating
The most important feature is the temperature rating. A -20 rating means it’s designed to keep you comfortable at that temperature. Always check the “comfort rating” too, which is often higher than the extreme rating. This tells you the temperature at which an average person can sleep comfortably.
Shape
Sleeping bags come in different shapes.
- **Mummy bags:** These are shaped to fit your body closely. They save weight and are warmer because there’s less empty space to heat up. They can feel a bit snug for some.
- **Rectangular bags:** These are roomier and more like a blanket. They offer more freedom to move but are usually heavier and not as warm as mummy bags.
- **Semi-rectangular bags:** These offer a balance between mummy and rectangular shapes, giving you a bit more room than a mummy bag but still being quite warm.
Hood and Draft Collar
A good hood stops heat from escaping your head. A draft collar is a tube of insulation around your neck and shoulders. It seals out cold air, making a big difference in warmth.
Zipper
Look for a zipper that runs smoothly. A two-way zipper lets you open the bag from the top or bottom, which is great for ventilation. Make sure the zipper has a flap to stop cold air from getting in through the teeth.
2. Important Materials
Insulation
The warmth of your sleeping bag comes from its insulation.
- **Down:** This is nature’s best insulator. It’s lightweight, compressible, and very warm. However, down loses its warmth when wet. Look for fill power (like 600, 800, or 900) – higher numbers mean better warmth for less weight.
- **Synthetic:** Made from polyester fibers, synthetic insulation is cheaper and still keeps you warm even when damp. It’s usually a bit heavier and bulkier than down.
Shell and Liner
The outer shell should be durable and water-resistant to protect the insulation. The liner should feel comfortable against your skin. Look for materials like nylon or polyester.
3. Factors That Improve or Reduce Quality
Construction Quality
Look at how the bag is made. Stitched-through construction is lighter but can create cold spots. Baffle box construction is more complex and expensive, but it keeps the insulation evenly distributed for better warmth.
Weight and Packability
For backpacking, you want a bag that’s light and packs down small. Down bags are generally lighter and pack smaller than synthetic ones.
Durability
Strong zippers, reinforced seams, and tough shell fabrics mean your bag will last longer. A good bag is an investment.
4. User Experience and Use Cases
Who Needs a -20 Bag?
A -20 sleeping bag is for serious cold weather adventures. This includes:
- Winter camping in snowy or freezing conditions.
- High-altitude trekking where temperatures plummet.
- Emergency preparedness for extreme cold.
- Anyone who gets cold easily and wants extra warmth.
How to Use It
Always use a sleeping pad under your bag. The ground can suck heat away from you. Wear dry, clean base layers to bed. Don’t breathe into your bag; your breath adds moisture. Keep your sleeping bag dry when not in use. Store it loosely in a large mesh bag, not compressed in its stuff sack, to keep the insulation fluffy.
Frequently Asked Questions
Q: What does a -20 sleeping bag rating actually mean?
A: It means the bag is designed to keep an average person warm and comfortable at 20 degrees Fahrenheit (about -7 degrees Celsius) below zero. Some bags have a “limit” rating, which is for survival, not comfort.
Q: Is down or synthetic insulation better for a -20 bag?
A: Down is lighter and warmer for its weight, but it’s expensive and loses warmth when wet. Synthetic is better if you expect damp conditions, as it stays warm even when wet, but it’s heavier and bulkier.
Q: Can I use a -20 sleeping bag in warmer weather?
A: Yes, you can. You can unzip it to ventilate, but it might be too warm for mild nights. It’s best used for its intended cold-weather purpose.
Q: How do I clean my -20 sleeping bag?
A: Always check the care label. Generally, you should wash it by hand or on a gentle cycle in a front-loading washing machine with a special down or synthetic cleaner. Do not use fabric softener.
Q: What’s the difference between a mummy bag and a rectangular bag for cold weather?
A: Mummy bags are more efficient at trapping heat because they fit your body closely. Rectangular bags offer more room but let more cold air in.
Q: Do I need a sleeping pad with a -20 bag?
A: Absolutely! A good sleeping pad is crucial for insulation from the cold ground. Look for one with a high R-value (insulation rating).
Q: How important is the hood on a -20 sleeping bag?
A: Very important. Your head can lose a lot of heat. A well-designed hood, especially with a cinch cord, helps keep you much warmer.
Q: What is “fill power” for down sleeping bags?
A: Fill power measures how much space down takes up for its weight. Higher fill power (like 800 or 900) means the down is loftier and provides more warmth with less weight.
Q: Can I layer inside my sleeping bag?
A: Yes, you can. Wearing thin, moisture-wicking base layers and a hat can add extra warmth. Avoid cotton, as it holds moisture.
Q: How should I store my -20 sleeping bag when I’m not using it?
A: Store it loosely in a large mesh or cotton storage sack. This allows the insulation to stay lofty and maintain its warmth over time. Don’t keep it compressed in its stuff sack.
