What are Temperature Ratings For Sleeping Bags?

You should always see the temperature rating of the sleeping bag before you buy it. They are often given comfort and extreme ratings. These numbers tell you the temperature range the bags can work best in.

Comfort Rating

You may see a comfort rating in the description of the sleeping bag that you want to buy. It means that the number given is the temperature range that it works best in. If the temperature is above or below the number given, you will be either colder or warmer than you want in the sleeping bag.

Extreme Rating

Sometimes that temperature rating of the sleeping bag is given as an extreme rating. The number given with it is the survival temperature of the sleeping bag. If the temperature falls below or above it, the sleeping bag would not be helpful.

What’s the Difference Between Down and Synthetic Sleeping Bag?

Down Sleeping Bag

Down is a type of insulation material that is used in some sleeping bags. It is made of the fine under feather of either duck or geese. It has excellent heat retention ability. The loft of the down produces small air pockets, which help it trap heat inside the bag. This material is also light and compressible. But their one downside is that they take longer to dry, so they are recommended for cold and dry conditions.

Synthetic Sleeping Bag

Synthetic material is commonly used in sleeping bags for insulation. It is usually made of human-made poly fibres. It requires less care, and it is cheaper than down. They are easy to clean and dry out faster. But where it lacks is the heat-trapping ability. It doesn’t provide as much warmth as the original down.
