Sling Bag vs Backpack vs Luggage Bag

There are three types of commonly used bags as everyone needs one that are sling bag, backpack, or luggage bag. While hanging any sort of bag for such a long time, have you ever question yourself why your shoulder or back is painful or tender after carrying a bag? Or do you ever wonder if your kids or little ones are getting the most suitable or perfect bags for their posture and growing body, or are they going through with the same problem?

Do seriously consider these small questions so that you can quickly figure out the correct solution instead of changing the bags again and again.

Here we will let you know the differences between these three bags, and also, let’s look at how each type should be carried so that you can avoid sore shoulders.

Sling Bag:

A sling bag is a common term used for a kind of handbag. Sling bags have an extended strap that can hang from your shoulder or across the front side of your body.  The shoulders’ outline is that the part that is close to the neck’s base is usually higher or raised than the tip of the shoulder, so it generates a natural “downslope.” Therefore, when you drag a sling bag only on one shoulder, the tendency or probability is for the bag to slide off from your shoulder. In order to halt the bag from sliding, one usually has to lift up the shoulder on the exact same side to level the “downslope.

The correct and appropriate way to carry a sling bag is to maintain or wear it with its strap across the chest. By doing so, the entire weight of the sling pulls the belt towards the base of the neck (the “cross” effect) rather than slipping off the shoulder. Thus, there would not be a need for the shoulder to uplift excessively. Another great advantage of carrying a sling bag across your chest is that the weight can be supported entirely by the back or hip; the downward pull on the shoulder is also significantly less, which helps you to reduce the risk of over-using the neck and your shoulder muscles.


A backpack is simply a form of cloth sack carried on one’s back and protected with two straps that go above the shoulders, but it can have an exterior frame, internal frame, and there are bodypacks. There are many kinds of designs in backpack trending. However, they all share one thing mutual: there are two straps and one on every shoulder. Therefore, the bag will not slip off your shoulder easily as compared to the sling bags. Hence, there will be less or no risk of neck/shoulder overuse injury. If the backpack is carried only on one shoulder with only one strap being used, it will turn into an “upgraded sling bag.” This may lead to several issues, as stated above as well. While carrying a backpack, the extent or length of the strap is most important. If it is too long, then the pack will “lean backward.” This ultimately leads to either a much-hunched spine, or even in elevated shoulders, or both at a time.

The primary key is to adjust and accommodate the strap’s length according to your body so that the backpack stays close and intact in contact with the back. If possible, appearance for bags that have front straps that cross the abdomen/chest. These straps can hold the backpacks quite closely to the body. The firmer and closer the pack is to your body, the less movement of the bags. As such, the less the body requires to work to carry it with you for an entire day.

Luggage bags:

Lastly, a suitcase or a luggage bag is often a somewhat flat, rectangular-shaped bag with rounded square edges, either metal, rigid plastic, or even made of cloth, vinyl, or leather that more or less sustains its shape. Carrying or pulling a luggage bag is probably easier and comfortable for your back as the load is entirely on the ground. It has less or no impact on back posture. However, if the handle’s length or measurement is not adjusted correctly, you can be in a problem. For example, if it is too short or small, one needs to turn and bend to the side to drag the bag. This may lead to severe back strain. Similarly, on the other hand, if the handle of your luggage bag is too long, one would need to excessively put effort lift the shoulder to accommodate the position of the handle. This is also not ideal for your body posture.

The key or the correct way here is to ensure an appropriate length of the handle. This is so that when you drag your bag, your shoulder should remain down and stress-free with your elbow bent slightly. There should not be any turning or side-bending of the trunk as well. Last but not least, the weight of the luggage bags should not be too heavy to cause likely arm muscle strain. This is especially when your travel time required is long and hectic.
