Why it is difficult to choose a sleeping bag
Choosing a sleeping bag is a very important choice in camping. Because it is directly linked to life support. If you sleep in a low -performance sleeping bag in the middle of winter, you will fall into hypothermia and you will be in danger of life.
On the other hand, if you use overspec sleeping bags in spring and autumn, you will not be able to sleep because it is hot.
And another, high -performance sleeping bags are expensive.
It is a difficult choice for beginners who have no particular experience because they have to choose a sleeping bag in consideration of the balance and priority of this “performance”, “season to use”, and “price”.
This time, it can be used in spring and autumn, and the price range is not too expensive to use the MONT-BELL sleeping bag “Down Hugger 800 #3” to verify that you can sleep comfortably even in a certain cold situation.

inspection result
10:00 PM.
I went to bed. At this point, the outside was already cold and unbearable without a bonfire.
I didn’t feel much of the sleeping bag “warm”. However, there was no feeling that it was cold.
Because it was extremely flat, you can see that it keeps warmth.
As a result, I slept normally until morning.
However, I woke up about a few times when my feet got cold and my sleep became shallow.
People who are cold or cold require measures such as warming their feet separately in this environment.
I woke up at 6 o’clock in the morning, but the temperature was 6 ° C, so it can be used without any problem with this temperature. When I woke up, I didn’t feel cold.
Another thing, it has nothing to do with warmth, but this sleeping bag was light anyway.
I didn’t feel much weight, and it was easy to turn over, so it was easy to move after entering a sleeping bag.
On the next page, we will conduct additional verification in an even lower temperature environment.
