How to Choose Your 3-Season Sleeping Bag?
Here are the essential criteria to take into account when choosing a three-season sleeping bag.
A good sleeping bag is above all a model that can be bulky. If you remember the square-shaped and colorfully colored sleeping bags that your parents or grandparents used, you still remember their weight and volume.
Today, sleeping bags are available in both light and highly insulating. The weight of the sleeping bag will change according to its insulation power. Thus, three-season sleeping bags are heavier than one- or two-season models. Heavy and bulky bedding quickly becomes a major inconvenience when you are hiking.
Of course, staying warm is important, so you’ll need to find a good balance between lightness and warmth. A good solution is to have several models that will adapt to all seasons and all weather. If your budget does not allow it, choose a bag that will allow you to stay warm according to your use.
If you don’t plan on hiking outside of the summer season, you can opt for a one- or two-season down jacket. You can choose one two seasons and one ultralight three seasons. In this way, you can make do with these 2 bags and not invest in a 4-season or extreme cold duvet.
In a sleeping bag, heat is created by your body and thus heats the interior space of your bag. It acts as an insulator. In other words, the more insulating the sleeping bag, the warmer you will be. Similarly, the smaller the space to be heated, the faster it will heat up. This is why sleeping bags have evolved over time into a mummy shape, more convenient than the square shape of yesteryear.
If you are looking for warmth, opt for a model adjusted to your size that will best adapt to the shape of your body. Double sleeping bags for romantic camping have this defect in that they are often too big, thus increasing heat loss. Pairing two sleeping bags or double sleeping bags can be very nice for lovers. However, they are not recommended for hiking in cold areas.
Humidity often exacerbates the feeling of cold. At night, the humidity drops. For lovers of nights under the stars, it is essential to bring a sleeping bag that is sufficiently waterproof to protect against outdoor humidity, even during the summer period.
Type of use
3-season sleeping bag (spring/summer/autumn) is certainly the most versatile type of sleeping bag and our favorite. It is also the most common. Usable in autumn and spring from -10°C but also in summer by opening the zipper, this sleeping bag covers all needs. It is ideal down for the mountains. However, it is necessary to pay attention to its weight, this great insulation has a cost and there are rather heavy models.
Your comfort depends on the insulation of the sleeping bag. Moreover, a small space heats up at a faster rate than a large space. If you choose a sleeping bag adapted to your size, your bedding will be warm quickly.
To help you find your way around, three temperatures are indicated on the sleeping bags:
- Comfort temperature: temperature from which you are in thermal equilibrium and you do not feel the cold.
- Comfort limit temperature: the minimum temperature for which, curled up on yourself, you hardly feel the cold.
- Extreme temperature: temperature from which the risk of hypothermia appears.
Shape: Rectangle, Mummy or Quilt?
Among the many forms of sleeping bags available, we will focus on the most common:
- Rectangle shape: as mentioned above, this shape is comfortable, giving you more space in the legs and feet. It is suitable for mild temperatures, during the hottest months of the year. In addition, this shape does not cover the head and it takes up more space in the backpack. This is a model now outdated.
- Mummy shape: this shape is ideal for the colder months of the year. The bag adapts to the shape of your body thus reducing the interior space. The mummy sleeping bags are generally equipped with a hood to maximize the insulation at the level of the head. This is the most popular fit in the sleeping bag market today and is the fit for both of my sleeping bags.
- Quilt shape: This is a sarcophagus shape that is open in the back. The idea is that the part of the bag is located under your back. In other words between you and your sleeping pad. It is ideal for hikers who wish to optimize the weight of their equipment. This fit will not be suitable for those of you who sleep on one side. This shape is not equipped with a hood, so remember to take a very warm head cover.
Insulation: Down or synthetic?
Two types of insulation are available to you: down and synthetic.
Down sleeping bags are made from the feathers of young birds (usually geese or ducks). They’re lighter and more compressible. They allow optimal insulation and are more durable than synthetic bags if they are well maintained. On the other hand, they are relatively expensive, absorb moisture more easily and therefore take longer to dry.
Synthetic material sleeping bags absorb less moisture, dry faster, and are easier to maintain. They also cost much less. They are heavier and bulkier offering a less interesting weight/insulation ratio than a duvet.
If you are looking for a sleeping bag for occasional, low-altitude hikes it is best to choose synthetic padding. It will ensure optimal comfort and absorb less moisture.
However, if you are preparing for a hike lasting several days, in medium or high mountains and you practice walking quite regularly, goose or down sleeping bags will be less bulky and more insulating.
For me, the sleeping bag remains one of the essential elements of the hiker’s gear.
A hasty choice can spoil the whole experience. We hope that our guide will have allowed you to find your happiness. If you have any suggestions or questions, do not hesitate to post them in the comments, we will answer them very quickly.
See you soon and sweet dreams in the heart of nature.

Can a winter sleeping bag be used in the summer?
Yes, it is quite possible to use a winter sleeping bag in summer, just open it to ventilate yourself if you are hot. You can also use some models in cover mode by opening them entirely as with a rectangular model.
On the other hand, if it is a model for extreme conditions, you risk being too hot which could affect your comfort. It’s a bit like sleeping with a very big sleeping bag in the middle of summer.
1-person or 2-person sleeping bag?
For couples, there are two-seater sleeping bags called doubles. This option can seem romantic and have a very cocooning aspect. However, this type of sleeping bag being more spacious, it takes longer to heat up because they have more empty space. In addition, these spaces also cause heat loss, and therefore it can be difficult to maintain a stable temperature during the night.
It is better to opt for a sleeping bag that perfectly matches the silhouette. Of course, if you are traveling as a couple, the 2-seater model is possible, especially in summer.
