It is usually impossible to be perfectly comfortable when outdoors. In particular, sleeping arrangements have to be made prior with a lot of factors put into consideration. Therefore, it is important to take time when selecting your sleeping bag of choice.

It may save you a night of tossing and turn. The first step towards this is understanding the temperature ratings on different sleeping bags.

The 30-degree-rated sleeping bag is ideal for the summer. It offers just enough warmth for optimum summer temperatures. However, it can get too hot if temperatures exceed optimum. 

Temperature ratings 

Outdoor activities such as camping have many enthusiasts and people who just want to try it out. And different people have different physiological makeup.

Whereas some pride themselves on being survivors and can make it through the night regardless of condition or situation, others want to extend their comfort at home to the outdoors. 

For the ‘comfort-seekers’, choosing an ideal sleeping bag is vital for both survival and comfort. Generally, when it comes to rating sleeping bags, there is a lower limit which means that it is possible to survive but not be comfortable at that temperature.

For instance, the 30-degree rated sleeping bag is capable of keeping you alive at night at 30 degrees temperature. However, you are still likely to feel uncomfortable and cold. 

To that end, sleeping bags contribute significantly to the type of experience you ultimately have when outdoors. If you do not want to shiver throughout the night, you might put more thought when it comes to sleeping bags. It should not only keep you alive but also warm. 

A general rule of thumb is that your sleeping bag should be 10 degrees warmer than the lowest night temperatures. In the same vein, you should anticipate some sudden dip in temperature. The 10 extra degrees come in handy as a buffer and reduce the risk of hypothermia. 

Understanding climate 

Finding the best sleeping bag will involve you understanding the climate. It would be best to familiarize yourself with the extremes of climate and temperature differences in the areas you are looking to camp in. Inasmuch as the differences may seem small on paper, they can make a huge difference at night when you are sleeping. 

Understanding temperatures is instrumental. Temperature tends to fluctuate unexpectedly and very unpredictably. It is advisable to keenly monitor temperature forecasts.

Moreover, when considering temperature, think of it as what it would feel like rather than what it actually is. In this sense, do not ignore factors such as cloudy weather, wind chill, and unexpected weather conditions. 

Understanding personal differences 

Temperature ratings are simply a guide. They may not be so accurate as they are generalized and may not work out for everyone. This is due to personal differences. These differences can be categorized as follows; 


Generally, women tend to feel colder when they sleep. Some sleeping bag manufacturers may consider this and rate their bags differently for men and women. This is commonly done by reducing the ratings by 10 degrees for women. It is important to note that when you are in the market for a sleeping bag. 


Body circulation directly relates to the regulation of temperature via blood flow. People with poor blood circulation tend to feel colder quickly, especially in their hands and legs. Tight clothes also hinder proper blood circulation to the legs. 

Muscle mass 

Muscle mass plays a key role in the body’s temperature regulation. People who have a lower ratio of muscle mass to body surface tend to be colder. Also, those with the least body fat would be the coldest.
