  • Sling bag
  • Sling backpack
  • cross bag
  • Cross body shoulder bag
  • slingers
  • body bag
  • Triangle City Bag
  • One strap backpack

What are the advantages of a sling bag?

Imagine you have a backpack on your back and get on a crowded subway, tram, train or bus. That’s pretty exhausting, because you simply take up too much space with the backpack. Whenever you turn around, your backpack will bump into fellow travelers and cause trouble.

If you want to sit down, you have to take off your backpack beforehand, which is quite difficult in the dense crowd.

This is where the advantages of a sling bag come into play. Because such a slinger sits much closer to the body and takes up significantly less space than a backpack. If you want to sit down, you don’t have to take off the slinger, you can simply turn it on your body onto your chest.

Worn in front of your chest, you always have your valuables in view. This is also very valuable as theft protection in dense crowds. 

Another advantage is that you can easily get to your things without removing the sling bag. If you want to get something out, you just have to twist it onto your chest and you have access to the contents.

What are the disadvantages of a sling bag?

A disadvantage of the slinger is that you cannot use it to transport heavy things over long distances. On the one hand, it simply doesn’t offer enough space for this, and on the other hand, the weight in it is not evenly distributed on the back.

The sling bag is therefore only recommended for light luggage.

Advantages and disadvantages

In summary, the advantages and disadvantages are as follows:


  • Can be worn flexibly on the back and in front of the chest
  • Quick access to content
  • Doesn’t need to be removed to sit down
  • More convenient on public transport


  • Limited space
  • Not suitable for heavy objects
  • Worse weight distribution than a backpack

What are sling bags used for?

A sling bag is often used for walks, excursions, short trips and city trips. It also has tangible advantages in local public transport. Whenever you only have to carry a few items with you in everyday life, a slinger is quite practical.

Photographers also like to use slingers for their equipment, as they have much easier access to their equipment than with a backpack.

Sling bag or backpack? What is better?

It depends. If you only want to pack light for a stroll through the city, then a sling bag is definitely a good choice.

However, if you need to transport heavier things, such as a notebook, books or other bulky or heavy items, then a backpack is much better suited.

It is best to have both a good backpack and a slinger at home. Because these two pieces of luggage do not compete with each other, but complement each other splendidly. So you are well prepared for all situations and always have the right bag at hand.
