Outdoor sleeping bags are the basic thermal barrier for mountaineering in autumn and winter.
In order to get a good night’s sleep in the mountains, some people even brought heavy sleeping bags but it was still cold. Some people’s sleeping bags look small and convenient, but they are also fluffy and warm.
Faced with all kinds of strange outdoor sleeping bags on the market, have you chosen the right one?
sleeping bag, the most “reliable” outdoor partner
Outdoor sleeping bags are a large piece of equipment for mountain friends, especially when camping in the mountains, the role of sleeping bags is even more important.
In winter, when camping in cold weather, mountain friends are not only prone to cold feet, but also cold hands and even cold abdomen. At this time, a cold-proof sleeping bag can allow you to retain precious heat and fall asleep warmly.
Even in summer, the mountain climate is often “different” between day and night. Walking during the day is still profuse sweating, and the temperature drops at night.
According to the monthly low temperature average of the main mountain peaks in China, a good sleeping bag can lock us in exclusive warmth at all times in a specific outdoor environment.
In the face of a wide range of brands and types of outdoor sleeping bags, when choosing a suitable sleeping bag, the key is to rely on these points to make the mountain friends truly “warm as ever”.
When choosing a sleeping bag, what is the key to choose?
When Shanyou buys outdoor sleeping bags, the brand determines the quality of the sleeping bags to a certain extent.
Offline stores like Decathlon can provide a one-stop solution for outdoor newbies to have a direct understanding of the texture of sleeping bags.
The brand of the sleeping bag is the label of the sleeping bag
if you want to choose a sleeping bag with good looks, like the sleeping bags of Mugao Di and Norke, you must not miss it. If you want better thermal insulation, sleeping bags from black ice, Tianshi, and Kaileshi are also good choices for the price.
For local tyrants with unlimited budgets, Xishan must be the god of sleeping bags, but the only disadvantage is that it is expensive.
The air holes inside the Xishan sleeping bag are tightly formed without dead ends, creating a 17-centimeter-thick thermal insulation layer even in ice and snow.
No matter which brand of sleeping bag you choose, you must choose a suitable sleeping bag according to the specific environment.
Each sleeping bag has a temperature reference table
when mountain friends choose a sleeping bag, they must first understand the temperature of the area they are going to, and then choose the comfort of the sleeping bag according to the camping site.
Usually, you can refer to the comfortable temperature and comfortable height of the sleeping bag as the standard for purchasing a sleeping bag.
For example, the night temperature in the camp is about -13 degrees, it is best to choose a sleeping bag with a comfortable temperature scale of about -15 degrees to prevent sudden cooling.
Comfort temperature: The minimum ambient temperature for a standard woman to sleep comfortably in a relaxed position in a sleeping bag without feeling cold
Minimum temperature/limit temperature: The minimum ambient temperature at which a standard male is curled up in a sleeping bag and does not feel cold
Temperature extremes: The lowest ambient temperature at which a standard woman can curl up in a sleeping bag for 6 hours without shivering but not hypothermic
Upper limit temperature: the highest ambient temperature at which a standard male head and hands are stretched out of the sleeping bag without sweating
Therefore, the temperature scale of the sleeping bag is the first thing to pay attention to. If the temperature scale is not suitable, no matter how good the style and design are, it will not work. Secondly, the warmth of a sleeping bag depends largely on its thermal insulation material.
Good sleeping bags and bad sleeping bags are marked with the same temperature scale, but the actual use is very different. In addition to down, bad sleeping bags will be filled with other fillers to reduce costs and greatly reduce warmth retention. , the breathability of the fabric is also very different, so don’t just look at the temperature scale and be greedy for petty cheap.
The key warm sleeping bag “lining”
the sleeping bags of mountain friends mainly include down, chemical fiber cotton and fleece, and down sleeping bags are divided into duck down and goose down.
From the comprehensive consideration of environmental humidity, temperature, sleeping bag volume and sleeping bag weight, you can choose a suitable sleeping bag according to your own situation:
For camping in warm, wet areas, consider a cotton or fleece sleeping bag
Use down sleeping bags in areas with cooler nights
Down sleeping bags can also be considered when a sleeping bag is required to be small or light in weight
The key factors that mainly affect the warmth of the sleeping bag, also need to pay attention to the filling amount, cashmere content and bulkiness of the sleeping bag at the same time.
Down filling capacity
refers to the filling weight of down in the sleeping bag, such as 1300 grams of duck down sleeping bags, 400 grams of goose down sleeping bags. The same filling, the higher the amount of down filling, the higher the warmth retention. (Note: The amount of down filling should not be too high, otherwise the down will squeeze each other and the captured air will be squeezed away, which is not conducive to keeping warm)
For example, at low altitudes in summer (1000-2000), you can choose between 400g-700g of down filling
High altitude (1500-3500 meters) in spring and autumn can choose between 700g-1000g of cashmere filling
High altitude (3500m-5500m) mountaineering activities can choose between 1000g-1500g of down filling
down is composed of feathers and down, the feathers play a supporting role, and the warmth mainly comes from fine down. The ratio of down and down is called down content. The higher the down content, the warmer you are.
Under the same fleece filling, the higher the bulkiness, the better the thermal insulation effect. Under the premise of the same warmth, the higher the bulkiness, the lighter the sleeping bag and the easier it is to compress.
Which outdoor sleeping bag is best for you?
As an outdoor equipment for keeping warm overnight, mountain friends need to choose outdoor sleeping bags of different designs according to the geographical environment and altitude.
Mummy style sleeping bag (also known as mummy style)
a close-fitting design with wide shoulders and narrow feet, (shoulders 75-85 cm, feet 45-55 cm) has a good thermal function, can cover the head, and is very suitable for mountaineering Use on foot.
In the outdoor environment below 0°, it is almost always found.
When mountain friends are hiking and camping at low altitudes, considering that they generally need to carry their own equipment, they often choose mummy-style sleeping bags that are relatively small in size and light in weight.
For high-altitude mountaineering, considering that there are caravans specially designed to carry equipment, the thermal performance of sleeping bags is mainly considered. If it is summer climbing, if the camp is at an altitude of 3000-4000 meters, it is recommended to use a sleeping bag of 1000 grams; if the camp is at 4000 meters, it is recommended to use a sleeping bag of more than 1300 grams.
Envelope-type sleeping bag
shaped like an envelope, the shoulders are as wide as the feet, the interior space is large and easy to move, often when mountain friends are doing ordinary camping activities, the envelope-type sleeping bag can also be connected by a zipper, and the same style of sleeping bag. Pieces together to form a double sleeping bag.
