Comfortable or not:
Each person's body temperature is different. In the same sleeping bag, who is comfortable and who can get in trouble. Here are some things to keep in mind. Lying on a sleeping pad or something will be much less cold, as the feeling of flattening under the pressure of the body will keep the bottom of the sleeping bag cold. As the heat will build up your body, you need to have a full stomach and drink plenty of water. If you sleep on an empty stomach, you are more likely to catch a cold. And remember that the sleeping bag (stuff shack or compression shack) that you have when you buy a sleeping bag is only for trekking or moving time. When not in use, it should be taken off and folded like a cloth. Pressing the inside of the pack will reduce the feeling of fullness.
Temperature rating:
Just as skinny clothes are different in different environments and seasons, sleeping bags are also different for different temperatures or environments. With the sleeping bag I would be camping in Wyoming, I would not be able to stay in minus temperatures in Alaska or Canada. In the same way, in a bag suitable for minus temperature, I can't sleep in the hot spring season of Wyoming, it will feel hot.
Sleeping bags are usually rated as Comfort Level and Lower Limit / Extreme Limit. The temperature depends on how thick the inner filling is, the shell material or the quality of the fabric on top and the shape of the bag. The more fluffy or fluffy the filling, the better. Keep in mind that sleeping bags do not generate any heat on their own, only trap your body's warmth from the cold weather outside.
So when we buy, we have to make sure that the sleeping bag can cover the temperature of the environment in which I will be camping. Example: If I sleep in a mountain house most of the time in the mountains, then the temperature there should drop to 8-10 at night. As such, my sleeping bag must be below 8 degrees Celsius. Comfort level for girls, comfort level for boys, and lower limit if not available
When the temperature is high, open the chain of the bag and arrange ventilation, it will take less heat.
Shape and size:
Sleeping bags are usually of three shapes.
Completely rectangular shape, it is called envelope or rectangular shape and semi rectangular and semi envelope shape. Summer sleeping bags usually come in this shape.
Mummy sleeping bags are shaped like human bodies as in Egyptian pyramid. The feet are pressed and the head can be covered. This type of bag can hold the temperature very well only because of this shape. There is less air trapped in the feet, which warms the body in less time, making it less cold. Due to being pressed towards the feet, it takes up less space than a rectangular bag after packing and is a bit lighter in weight. Although it is good in all respects, those who feel comfortable sleeping with their hands and feet together find it difficult to sleep in this type of bag. Sleeping bags are always mummy shaped for extreme cold (below 0 degree) weather.
Some sleeping bags are found in the middle of a square and mummy shape, with a hood on the head and slightly pressed on the legs without being fully pressed. Those who like mummy Shape but do not feel comfortable sleeping can try these.
Outer shell: The upper layer of the sleeping bag is called the shell. Usually made of polyester or nylon. The top shell of a good sleeping bag is water repellent so that the filling inside is not damp or damp. To understand whether the shell of the bag is water repellent, if you drop a drop of water, the water will drip and fall off, and if the cloth absorbs water, then you have to understand that it is not water repellent. Ripstop nylon is more durable, softer and lighter in weight than polyester.
Material used in sleeping bag:
Filling: Outdoor sleeping bags for backpacking and camping can use two types of filling, down or synthetic fiber.
Down: Made from soft fur under the feathers of a bird. Weight is very low. When packed, the size is much smaller. Usually 600 fill power down is used. Fill power is the measure of how many cubic inches of space one ounce of weight occupies. The more bags you get, the lighter and more fluffy the bag. All sleeping bags and jacks of extreme temperature are made with goose down or duck down. Very good insulation but the price is much higher. Downhill is another problem that usually comes down to the fact that there are special methods and soaps for washing down anything that is not readily available. In addition, if for some reason the down sleeping bag gets wet, it takes a long time to dry and there is a possibility of damage. This type of bag is only suitable for extreme temperature expeditions. Not suitable for areas where the temperature is above 5 degrees Celsius.
Synthetic Fiber: Like polyester foam, this filling is commonly used in jackets and moderate sleeping bags. Weight and size are more than down. Cheap and easy to wash. Measured in grams with square meters or g. For example, 100 g means 1 square meter, this fiber will weigh 100 grams. They are much cheaper than down
The inner fabric is called lining. Usually made of soft nylon or polyester. Nylon lining tends to be more comfortable and soft than polyester.
