How to choose a sleeping bag
With so many great choices, deciding on a sleeping bag can take time and effort. Make it easier by following this expert advice to determine the best sleeping bag for you.
Temperature rating
A sleeping bag’s temperature rating refers to the lowest temperature at which the average person will stay warm and comfortable while using the bag. Therefore, you want to choose a sleeping bag rated to the lowest temperature you expect to encounter on your trip.
Of course, you don’t want to be cold on your camping trip, but there is such a thing as a sleeping bag that is too warm. If you’re camping in warm weather, selecting a sleeping bag with less insulation will help prevent overheating.
Insulation type
The two main types of insulation used in sleeping bags are down and synthetic. The type of insulation can affect the water resistance, weight, warmth, and price of a sleeping bag.
Down-fill sleeping bags are rated by fill power. Fill power measures how many cubic inches one ounce of down takes up, with a higher fill power correlating with a higher quality and lighter weight sleeping bag.
Generally, down sleeping bags are:
- Longer lasting and more durable
- Offer a higher warmth-to-weight ratio
- More compressible
- Less insulating when wet and take a while to dry
- More expensive
Synthetic sleeping bags are usually made with polyester, and when compared to down, are:
- More water-resistant
- Insulate better when wet and dry quicker
- Less expensive
- Bulkier, offering less warmth-to-weight
- Not as long-lasting or durable
Shape
There are two main sleeping bag shapes: mummy and rectangular. Mummy sleeping bags are tapered towards the bottom to retain warmth and reduce weight. Rectangular sleeping bags offer more room to move around but are bulkier and don’t retain heat as well.
Age and gender
While most sleeping bags are unisex and designed for adults, there are more and more options for women and younger campers to find high-quality sleeping bags that better suit their needs. For example, women’s sleeping bags typically have more female-friendly shapes and designs, and children’s sleeping bags are smaller and often come in fun colors.
