1. Fluffy sleeping bag.
Build a camp. The first thing you should do is take the sleeping bag out of the bag. As far as possible, let it be spread out in the tent, if possible, it is best to shake vigorously, or gently pat the sleeping bag, increase air flow, accelerate the sleeping bag fluffy. Only by allowing enough air to enter the feather, the feather's warmth can be maximized.
Choose a cushion, preferably a foam pad.
Even if you choose the best sleeping bag, if the mat is bad, it will be hard to sleep all night. It is very popular now, but the general air cushion can only handle more than zero camping. If you really want to get the most out of your sleeping bag, you need to bring at least one foam pad, or spend some money on a combination of air cushion and foam pad.
Try to split the sleeping bag.
In the tent, even when the wind is high, the biggest cold source is the ground. So if it is more than two people, try to put the mat together to block the moisture/air movement.
Pack your own layer or sock into your sleeping bag.
When you wake up, the hardest thing to do is to put hot feet into cold shoes, or to wear a cool coat on a warm body. In order to avoid this situation, it is recommended that you pack your intimate clothes into your sleeping bag so that you can not only heat the clothes in advance, but also avoid the "empty" sleeping bag. If you are camping in a low temperature environment, everything that is cold is recommended to be packed into a sleeping bag -- a gas tank, a battery, and a lithium battery -- in addition to clothing. So, we often recommend that you don't buy a sleeping bag "just right".
Don't sleep in your sleeping bag.
The moisture in the breath is the main cause of moisture in the tent. If you've been sleeping in your sleeping bag, that's the equivalent of all the moisture in your sleeping bag. Our advice is to choose a sleeping bag with a comfortable neck, which can be comfortably fastened to prevent cold air from entering the neck, without affecting breathing. Then pull down the hood of your sleeping bag to cover your head and allow your nose and mouth to breathe.
6. Do the defrosting work.
Camping in a colder environment, the water vapor that is exhaled during sleep will quickly clot in the accounts, sleeping bags and backpacks. And when you wake up and start moving, these frozen "ice scums" will melt and dampen your favorite sleeping bag. There are two ways to do this: first, cover up the equipment you don't want to get wet, but the disadvantage is that the sleeping bag is hard to survive, after all, it is not possible to find a device that is larger than the size of a sleeping bag. Second: beat the ice before it melts, which means you'll wake up before the temperature rises sharply in the morning and do the defrosting.
Put a straw next to your sleeping bag.
Drink don't want to in the middle of the action is too large, or your water with opening is too big to sit up to drink, we recommend for a straw or just with water bag, then put the water bag inside the sleeping bag when going to bed. It's convenient and warm to drink.
Want to urinate
You drink water and you want to pee. But some people try not to lose their body temperature, try to hold the urine, not out of the toilet. Not to mention how much pressure it will put on the bladder, which affects health, and the purpose of insulation, is not to be achieved. Because the body needs a lot of heat to warm up your body fluids. The easiest way is to have a "chamber pot" next to your sleeping bag. Drink as little water as possible before you go to sleep, regardless of whether you have urination or not.
The principle of hot water is timeless.
This is a technique known to all campers (and not even camping experience). Pour a bottle of hot water into your sleeping bag and heat your sleeping bag. In fact, let the hot air circulate inside the sleeping bag in advance. If the conditions permit, this method is always tried. The only bad thing is that sometimes the thermos leak.
