Your Guide to a 0-Degree Backpacking Sleeping Bag
Why Choose a 0-Degree Bag?
When you’re planning a backpacking trip in colder weather, a 0-degree sleeping bag is your best friend. It means you can stay warm and comfortable even when the temperature drops to freezing or below. This guide will help you pick the perfect one.
Key Features to Look For
- Temperature Rating: This is the most important thing. A 0-degree bag is designed for comfort down to 0 degrees Fahrenheit (-18 Celsius). Some bags have a “comfort” rating, which is for women, and a “limit” rating, which is for men. Always check both.
- Shape: Most backpacking bags are mummy-shaped. This shape hugs your body to keep heat in. It also saves weight and space.
- Fill Type: You’ll see two main types: down and synthetic.
- Weight and Packability: Backpacking means carrying everything. A lighter and smaller bag is better.
- Hood and Draft Collar: A good hood keeps your head warm. A draft collar is a tube of insulation around your neck to stop cold air from getting in.
Important Materials
Fill Materials
- Down: This is the fluffy stuff from under a bird’s feathers. It’s very warm for its weight. It also squishes down small. High-quality down is measured in “fill power.” Higher fill power means warmer and lighter. Down can get wet and lose its warmth, though. Some down is treated to resist water.
- Synthetic Fill: This is made from man-made fibers, like polyester. It’s usually cheaper than down. Synthetic fill stays warm even when it’s wet. It’s also more durable. However, it’s often heavier and bulkier than down.
Shell and Liner Materials
The outside (shell) and inside (liner) of your sleeping bag are usually made of nylon or polyester. These materials are chosen for being lightweight, durable, and sometimes water-resistant.
Factors That Improve or Reduce Quality
What Makes a Bag Better?
- High Fill Power Down: For down bags, a fill power of 650 or higher is good. 800+ is excellent.
- Baffle Construction: Baffles are the sewn sections that hold the fill in place. Well-made baffles stop the fill from moving around. This keeps you warmer.
- Water-Resistant Coatings: Both the shell and down can have coatings to help them shed water.
- Good Zippers: A smooth-working zipper that doesn’t snag is important.
What Can Make a Bag Less Good?
- Low Fill Power Down: This means less warmth for the weight.
- Poor Stitching: Loose threads or uneven stitching can mean the fill won’t stay put.
- Heavy Materials: If the shell and liner are too thick, the bag will be heavy.
- No Hood or Draft Collar: These are important for staying warm in cold weather.
User Experience and Use Cases
A 0-degree sleeping bag is perfect for winter camping, late fall, and early spring trips in mountainous areas. You can use it for backpacking, car camping, or even just sleeping outdoors on a cold night. People who sleep cold will also appreciate a 0-degree bag even in milder temperatures.
When you use your bag, remember to store it loosely in a large mesh bag. This keeps the fill from getting crushed. Always let your bag air out after use. This helps it last longer and stay warm.
Frequently Asked Questions (FAQ)
Q: Do I really need a 0-degree bag if it only gets down to 20 degrees where I camp?
A: It’s a good idea to have a bag rated lower than the coldest temperature you expect. If you tend to get cold at night, a 0-degree bag will keep you much more comfortable in 20-degree weather than a 20-degree bag would.
Q: Is down or synthetic fill better for a 0-degree bag?
A: Down is lighter and packs smaller, making it great for backpacking. However, synthetic is better if you expect to get wet because it stays warm when damp. For serious cold and dry conditions, down is often preferred.
Q: What does “fill power” mean for down?
A: Fill power is how much space one ounce of down fills. Higher numbers, like 700 or 800, mean the down is more lofted and will be warmer for its weight.
Q: How do I keep my 0-degree bag clean?
A: Spot clean small messes with mild soap and water. For a full wash, use a front-loading washing machine on a gentle cycle with a special down wash. Always air dry your bag completely.
Q: Can I make my sleeping bag warmer?
A: Yes! You can use a sleeping bag liner to add a few extra degrees of warmth. Wearing warm, dry base layers and a hat to bed also helps.
Q: What is a “mummy bag”?
A: A mummy bag is shaped like a mummy. It’s snug around your body, with a hood to cover your head. This design traps body heat effectively.
Q: How important is the draft collar?
A: A draft collar is a tube of insulation that sits around your neck. It’s very important for a 0-degree bag because it stops warm air from escaping and cold air from getting in.
Q: Will a 0-degree bag be too hot for warmer nights?
A: Yes, it might be. You can zip down the bag to vent heat if you get too warm. For trips where temperatures can vary a lot, consider a bag with a slightly higher temperature rating or a more versatile design.
Q: How much should I expect to spend on a good 0-degree backpacking sleeping bag?
A: Prices can range from $150 to $600 or more. Bags with high-quality down and lighter materials will cost more. Synthetic bags are usually more affordable.
Q: What’s the difference between a “comfort” and “limit” temperature rating?
A: The “comfort” rating is the temperature at which an average woman can sleep comfortably. The “limit” rating is for an average man. It’s usually best to choose a bag rated for colder temperatures than you expect to encounter.
