When traveling outdoors, what kind of backpack is the most suitable to choose?

We can generally divide backpacks into three categories, and backpacks below 30L are called small bags. A backpack of 30-45L can be called a medium bag, and a backpack above 45L is a large bag.

What is the importance of the size of these three types of backpacks when outdoors? In fact, small bags and medium bags are based on the length of travel time. Backpacks under 30L are usually used
for shorter journeys of one or two days.

Generally, most people choose a backpack of about 45L. Such a backpack is already very large and has enough space, but when we pack it, we will find that if the order of things is not right, then the
bigger bag is also packet.

Generally, a 45-liter backpack can last for a long time, and a camping trip of seven to fifteen days is possible. Of course, the longer you spend in the wild, the more food you need.

For backpacks above 55L, you can safely put all the supplies in. For beginners, the more equipment, the better. But for the more seasoned to go camping, a simple little bag is enough to pack all the
essentials.
