What is The Criteria to Choose A Quality Travelling   Backpack?

A quality travel backpack will be judged on its material. Whether for short or long trips, it must also carry a compact and lightweight design to avoid putting pressure on the user's body during the trip. The backpack material should use Canvas, nylon fabric to increase durability and can be waterproof to avoid getting the items inside wet. In addition, the use of durable materials will help the backpack reduce tearing during transportation.

Next, the zippers will need to be strong to increase security and avoid loosening which will cause the contents to fall out. The strap and body of the backpack will need to be equipped with a ventilation system and shoulder pads along with a sternum belt to fix the backpack firmly, avoiding the unpleasant smell from sweating. 

Moreover, the backpack should have recognizable signs, or at least should be equipped with a tracking tag in case of loss. Thus, users can access the system with the registered code to be able to search and locate the backpack when it is lost.

You should also go shopping so that you can try on the backpack before deciding to buy it. Because the backpack in addition to choosing the right size for your needs, must also fit your body shape, otherwise it will be difficult to carry.

Considerations about Additional Functions

If you often go far and the trip is long, you will need to pay attention to the selection of several extra functions. These functions will add convenience, as well as help you solve some confusing problems while on the road.

The first is a rain cover that folds up on the side of the bag. The rain cover will be very useful when you go into places that are in the rainy season. In addition, you also reduce the worry when on the move that a wet backpack prevents your footsteps on the road of exploration.

The hip belt and sternum stabilizer will take the weight off your shoulder muscles and vertebrae. If there is a hip belt, about 70% of the bag's weight will rest on the user's hip. Besides, if there is a fixed belt on the hip, users will feel secure because they know that the backpack will be stable and secured at all times.

The backpack should have a flexible strap. Adjusting the width or grip of the strap is very important when you want your backpack to grip or support and increase the weight on your shoulders and back.

There are additional clips on the side of the bag that can help users comfortably attach additional items such as keys, GPS devices when camping, climbing. If the original design does not have a hook, you can buy one outside and retrofit your backpack.

The divider frame, if there is more, will be very handy for users who need to separate items according to each function more. In addition, you can turn your backpack into specialized bags for cameras and laptops. Likely, the split frame also helps to straighten the bag and help stabilize the shape of the user's spine while carrying heavy loads.

Can I Bring My Backpack on an Airplane?

It depends on how big your backpack is. In case your backpack is within the capacity that below 25L to 35L, it would be calculated as carriage luggage, you can bring it up to the airplane and store it in the luggage compartment as instructed by the flight attendants. If the backpack has the capacity of 50L and above, it is counted as signed luggage, so you would have to buy the transport slot for your luggage. The charging fee would be counted based on your chosen airline and the signed luggage’s weight. 

In case your backpack contains fragile items such as lens mount cameras or any items that need to be carefully transported, you should put on a sticker that illustrates that there is a fragile item in the backpack. That would help the transport staff handle your backpack with care while taking on the transportation.
