Is A 30-degree Sleeping Bag Warm Enough?

Technology has not left the sleeping bag market untouched! That is how come you can now choose the temperature of your sleeping bag. However, what does that entail?

When you go out to shop for the sleeping bags, you will notice that most of the products will include the temperature description.

What is the meaning of the temperature ratings?

From a general perspective, that temperature shown on the product label, is the lowest the sleeping bag can excellently keep you warm. Initially, the rates were not necessarily standard. This is to say, it was not measured against what a hot sleeper or a cold sleeper requires.

A cold sleeper means that the person’s metabolism is low when they sleep. Such a person requires a little more insulation to keep warm. A hot sleeper has a high metabolism and so require lesser insulation to keep warm at night. 

How to read the sleeping bag temperature readings

You will notice that some American companies are already making steps towards standardized temperature ratings. Such companies are adapting the European Norm to acquire these sleeping bag ratings.

For example, you can see “EN-13537” on a sleeping bag. That is the rating of that bag from the uniform rating system. Other standardized labels would include REI, Mountain Hardware, North Face and Marmot.

In 2017, ISO took over the rating standardization. ISO testing and the EN one is similar, and one can comfortably address them as one.

There are other readings on the sleeping bags which you may need to understand.

Upper limit– This refers to the maximum temperature an average man can sleep comfortably. A sleeper at that temperature will not sweat excessively.

Comfort– This will refer to the lowest temperature a woman will sleep comfortably.

Lower limit– This is the lowest temperature at which a man can enjoy their sleep comfortably.

Extreme rating- This will refer to the lowest temperature an average woman can possibly survive through the night.

Will a 30-degree sleeping bag keep one warm enough?

When choosing your sleeping bag, how warm it can keep you is key. Weather changes will also determine how warm your sleeping bag should keep you.

When choosing your sleeping bag, you would rather have one that is “a little too warm” than one that is “a little too cold.”

Choosing your sleeping bag- Are there any other factors to check out?

When you get the sleeping bag temperatures right, you also need to get the other features you need in the bag right.
