Sleeping bags mostly come in three different shapes, but why do you need it? You just want something warm and comfortable to sleep, right? Perhaps weight is also a problem, but a form of a sleeping bag? Yes, the shape of the sleeping bag is important. In addition to the material used, the shape or design of a sleeping bag is the most important factor in determining how warm it is, how good it is and sometimes it is!
Mummy in shape
Mom's sleeping bags are narrower in the leg than in the head. They are similar to how the mummy is wrapped up, if you have ever seen it. Since your legs do not require as much space as your shoulders, this is a fairly logical way to build a sleeping bag. A tighter fit for mummy bags means that there will be less air inside the sleeping bag and less surface area between the warm interior and the cold look around you. The simple effect of this is that the sleeping bags for the mummy are usually warmer. Rather, they have better insulation and do not give as much heat, which brings you heat in a cold environment.
Mummy bags are also usually lighter because the design uses a little less material to wrap around you than a barrel. For these reasons, sleeping bags for mummies are usually preferable for light mountaineering, hiking and trekking.
Trunk shape
Now about sleeping bags in the shape of the trunk. With all the excellent qualities of a mummy bag, why do you want to look at a barrel or a rectangular shape?
Some people feel too clogged up in the mummy's tight fit. Claustrophobia If you are a type who likes to move his legs, throw and turn in his sleep, a sleeping bag with a barrel will allow you more freedom of movement at night.
If you are resting in the open cold, there is also the advantage that you can pack some of your gear in your sleeping bag with you. Definitely socks. And gloves. Some trackers and tourists even love to keep their shoes or boots warm in the morning, sleep with them in the bag! Larger barrel-shaped bags allow you to do just that. Just remember to keep dirty boots in a plastic bag so that they do not make your sleeping bag dirty. You can even use a small pouch that usually comes with a sleeping bag.
Rectangular image
A rectangular sleeping bag is the least warm of the three structures described here. Most sleeping bags have a rather large hole. It's nice to allow you — and your hands — to move in and out of the bag as you like. But at the same time, it also allows some of your body to warm up. For summer use this may not be a big problem. Rectangular sleeping bags are also usually one of the cheapest sleeping bags. A little more bulky. But for big use in the casual order rectangular sleeping bags is the best offer. In the end, you do not need a high-altitude mountaineering bag for a weekend summer camp on a local lake.
