- From how much money you got? . If the money does not reach you to a sleeping bag that it meets all your requirements, decide which is the most important factor: don’t go cold, be comfortable, use little space, carry little weight.
To decide that sleeping choice, look at the main features of sleeping bags bag, described below
The most common forms of sleeping bags are: Rectangular , Constricted and Mummy (or sarcophagus).
The rectangular are enough versatile, since you can open them easily when it of hot, and join it with another sleeping bag to create a “double” bag.
The waisted and the Mummy they tend to preserve best heat, since they leave little space for that escape the heat, and they also can be Compact in one smaller footprint.
Tip: If you need to conserve heat, choose a bag that is not very big to you, and where they remain not many spaces, otherwise there will be more heat air spaces, and the wind chill will be lower.
The weight depends on the material and the dimensions of the bag. If you want to lower the load you carry, choosing a lightweight bag can be good idea.
This depends on the thickness of the insulating layer, collar, latches and hood insulation.
Manufacturers often indicate the range of temperatures for which it was designed the bag. This gives a rough idea that temperatures can support. It is important that you understand the nomenclature used in sleeping bags:
Extreme temperature: temperature of limit inferior to that you can withstand before that the user may suffer serious damage in the body.
- Comfort temperature: Temperature with which the user feels comfortable in the sleeping bag.
- Maximum temperature: maximum temperature where the user feels comfortable inside the bag.
In this way, the lowest temperatures you will face, should be very close to the comfort temperature.
Tip: It is important to remember that the environment where the bag is will affect the final temperature you get. A well insulated floor and a closed tent will help keep the heat better.
It is a good point if the sleeping bag has a mechanism to prevent the fabric is taken by the closure, and this binding. It proves that you can open and close easily.
A good seal can also help to keep the heat in the SAC, but many closures in the bag can make more difficult keep it, as for example in the sacks that have closed toes. Search for protective bands covering the closure, if you need to keep warm.
A sleeping bag features the following components: filling, insulation layer, hood, collar and closure.
Thermal collar: is a collar that surrounds the neck and using cord allows you to conform to the upper part of the body to avoid losing heat.
- Locks: (see section on closings)
- Hood: It allows to protect the head from the cold. It works together with the collar to avoid losing heat through the top of the bag.
- Insulating layer: allows to isolate the cold from the outside. If you have a high thickness and is capable of storing air, it will deliver a better insulation. Materials
Below are some of the most typical materials used in the sleeping bags, and a brief description of the advantages and disadvantages of each.
Advantages: It is soft, absorbs the moisture generated by perspiration and in winter it retains heat. Cotton flannel feels very warm and is quite durable.

Nylon (Fsynthetic ibra): some plastic synthetics are nylon, polyester, and acrylic fibres. There are synthetic fibres of filling, such as: Quallofil, Izotherm, Hallowfill and Polarguard 3D.
Advantages: It is lightweight, durable, easy-care and protects from the cold. You can put in the washing machine without any problem. They are ideal for the summer, and does not lose its insulating properties if there is high humidity. If it gets wet, it dries quickly. Its price is lower.
Disadvantages: They get dirty easily, it doesn’t feel so warm like cotton and sweat it sticks to the skin. They are a bit heavier than the feather.
Pluma: the quality of pen is expressed in the mix for the amount of feather and his nerve. A sleeping bag with feather 90/10 is better than a 80/20. The amount of feather in a sleeping bag is expressed in cuin (cubic inches).
Advantages: It is the best insulator, can expand and compress better than fiber and takes up less space when the bag is inside its case, by what weighs less.
Disadvantages: They are more delicate than the synthetic fiber and avoid that they get wet or wet since it loses its insulation ability. You can also wash often such as fibers and it must be done with special products, because if not, feather cakes (apelotona) and created holes in the halls of the SAC. It is more expensive, if it gets wet dry it.
