What could be more comfy than lazily setting down into your sleeping bag at the end of a day in the great outdoors? It is however important that a sleeping bag meets the needs of the user. Here are some tips to help you find the right one for you.

Comfort rating

In general, there are three types of sleeping bags:

  • summer season, for temperatures above the freezing point;
  • three-season, for use in temperatures down to -10°C;
  • winter, which allows you to sleep without shivering in temperatures as low as -40°C.

There is also a fourth category, the four-season sleeping bag, whose comfort rating is between -15°C and -20°C. But these bags are too hot for use in summer, and we often group them together with winter sleeping bags.

To choose the right bag, you must think about how you will be using it over a given year, and identify the best comfort rating for a given user. A persons metabolism, diet and tolerance to cold are just some of the factors that should influence the final choice of sleeping bag. Thus, a person who is sensitive to the cold would be better off choosing a warmer sleeping bag, even if he does not plan to use it in low-temperature conditions.

Insulation

The quality of an insulation material is determined by its ability to retain air, which is not a good heat conductor. The more insulation can easily trap air, the more the sleeping bag will remain comfortable in lower temperatures.

Although many synthetic insulations have become increasingly effective, down remains the best insulation around: in fact, there is nothing warmer or more comfortable for a sleeping bag. As well, down sleeping bags have better compressibility, which makes it easier to carry and leaves more space in your backpack for other things.

However, down does have a downside:

  • when wet or soaked, it loses its ability to trap heat;
  • it takes a long time to dry;
  • it is not recommended for people with allergies;
  • it is more expensive.

Synthetic insulation is heavier, not as compressible and does not last as long as down, but is not as expensive. However, synthetic insulation do not absorb water as much, thus maintaining its heat index easier and drying quicker. As a result, it is are less prone to mildew.
