A key element for those who leave camp is the sleeping bag. The choice of this should not be left to chance since each model has technical specifications that adapt to different types of climate and uses. In this article, you will find the tips on how to choose the best sleeping bag.
When choosing a sleeping bag it is essential to know what climatic conditions we will find in our destination. A good choice of this implementation will keep us temperate and comfortable, whatever the outside temperature. Sleeping bags are able to trap and keep a layer of dead air – not circulating – close to the body. With body temperature, the air heats up and the bag becomes a kind of barrier between the outside air and the frozen ground. Important is to consider that when using a sleeping bag we must isolate the floor with a layer of clothing and a pad or mattress under the bag and know that the metabolism varies from person to person and the temperature ranges also change from brand to brand.
choose the best sleeping bag
When buying a sleeping bag it is important to consider several points. These include ranges of temperature, weight, heat loss, bag categories, shape, size, filling, closure, and storage to the experience to live in open-air adventures.
1. Temperature ranges
The sleeping bags have an identifier called Comfort Level. This level of measurement is the optimal temperature where the user will be tempered and will sleep pleasantly. The sack may be able to be lower or higher in degrees, but this is the temperature where it works best. It is advisable to choose a sleeping bag with a lower temperature range than the lower temperature expected at the destination. For example, if it has temperatures close to 0 ° C, it is recommended to choose a bag of -6 ° C instead of one of + 1 ° C. If the temperature stays higher than expected, it is easier to ventilate the bag for more air circulation.
The weight of the bag is also important if you need to go camping or to go to the high mountains.
3. Heat loss
Sleeping bags have the Thermolock System technology that reduces the loss of heat inside the bag through the closure. That is, how it is able to prevent the loss of body heat. This will depend on the material of the filling, the thickness of the insulating layer, the type of construction, whether it has accessories such as hood or collar, etc.
The shape of the bag directly affects your sleeping comfort and whether you can pack it to a smaller size or not. There are two main forms in sleeping bags, described below.
Mummy type: They are so called because the user can be accommodated like a mummy inside the bag, thanks to the incorporated hood. They are designed to save weight and maximize heat retention. They are wider on the shoulders and narrow on the feet and have a hood that covers the entire head and neck. This type of bags keeps the heat of the body inside it since they have less space to heat. They are ideal for outings in cold temperatures or simply for chilly people.
Rectangular type: These are the most conventional and common models that offer greater freedom of movement than mummy type sleeping bags. They grant greater comfort in any weather or climatic condition. Most of these sacks can also be opened and used as a down. Some also have an extension on the part of the head to keep it covered or more comfortable. They have enough space in the feet and head, but this becomes negative in extremely cold conditions as there is more room for cold air to circulate.
5. Special sizes
For those people who need even more space to sleep, there are XL bags that are longer and wider and others designed especially for women who fit perfectly in their bodies. They are narrower in the shoulders, wider in the hips and have greater insulation in the upper body and feet. Children can also count on a sleeping bag appropriate to their size.
Sleeping bags can come with natural or synthetic padding. Those of natural filling provide greater insulation but are heavier. Most campers choose bags with synthetic insulation for their good performance and price-quality ratio. They are made mainly of polyester and offer advantages such as easy drying, cold insulation. Even if they get wet, they are cheaper than a goose down, antiallergic and child and dog proof.
If you venture into the colder ground, you will appreciate a bag with a good hood, the Marmot Trestles 30 would be an excellent choice for you. As you probably already know, we lose most of our heat by the head so if you are the type to feel cold when you sleep, this option will ensure your comfort. Most sleeping bag hoods will have an adjustment cord that will allow you to adjust the opening to your liking.
Do you still hesitate between synthetic and down? If this is the case, the option of a sleeping bag shell may be able to decide for you. Unlike down bags, synthetics such as Mountain Hardwear’s Lamina Z Flame often have a shell-like exterior treated with a water repellent solution. Just like a raincoat, this allows water to bead on your sleeping bag and therefore keeps it dry. We have provided tips on choosing the best sleeping bag hope you can buy a good one.
