Things to Consider in Before Buying a travel backpack :

There are many factors that must be considered while choosing the right kind of backpacks. Let us have a look at some of the essential factors:

Water Resistance

  • One thing you should consider when choosing your hiking or camping backpack is water-resistance. Even if is not 100% waterproof, a backpack with water-resistant material will make your camping and hiking trips a bit easier. It will keep your items from getting wet in the rain.

  • It is not enough to choose a backpack with water-resistant material. You should also check if it can dry in a quick amount of time to avoid it getting musty. We advise you to look for a backpack with a thick but lightweight material. Treated nylon is especially good so look for a backpack made of this material.

Lockable Compartments and Zippers

  • Safety is a main issue especially when you are travelling. That is why is it very important to choose a backpack with lockable compartments and/or zippers.

  • One advantage of having lockable compartments, aside from preventing people from stealing your stuff, is that people won’t be able to put anything in your bag.

  • Another thing is for added peace of mind when travelling.

  • We recommend you buy TSA-friendly locks for your backpack. These locks have a special release valve that allows the TSA to open your bag without breaking it.

  • You could also look at getting Pacsafe. It wraps a mesh around your whole bag which you can lock and tie to an immovable object. It is especially useful when leaving your bag unattended for a long time. Do note that the mesh is a bit heavy and might be hard to carry around.

Multiple Compartments

  • Multiple compartments are not a must in a backpack but there are very welcome. These allow you to organize your items better and allow easy access to frequently used ones like your phone or water bottle.

  • You should also consider backpacks with laptop and/or gadget sleeves if you use these items. They will provide added protection for your gadgets as well as grant easy access to them.

Frame Type

  • Most of the modern backpacks have internal frames on them. Internal-frame packs have frames and support rods embedded into the bag and are hidden from view. These provide great durability and support. Internal-frame backpacks look better that their external-frame counterparts. 

  • You can also move in them fairly easily since the rods won’t get caught in anything with them being inside of the bag. These also tend to be lighter and made from carbon fiber or tough plastic.

  • External-frame backpacks have their frame on the outside instead of being hidden. These are typically found in older backpacks. We recommend you stay away from external-frame as they can be quite clunky and hard to move around in.


  • Padding is really important in choosing your backpack. These help you carry back for long periods of time which is really important when you are hiking.
  • A padded hip belt will provide greater support for your back where you will carry the most weight. It will also make carrying your load a bit more comfortable. We recommend your look for an adjustable one so you can tighten or loosen it for more support.
  • Padded shoulder straps will also help you carry your pack easier. They will help take pressure off your shoulder and lower back. You should make sure that that padding is thick and durable.
  • Lastly, look for a pack with lumbar support. This will help in distributing the weight evenly as well as providing more comfort for your lower back. It also allows for a natural arch for your back.

Front-Loading or Top-Loading

  • A front-loading backpack means that the backpack will allow you to zip open the side to let you access your items. A top-loading backpack however only allows you to access your items from the top of the pack.
  • We recommend you look for a front-loading backpack because it will allow you to access your items easily than a top-loading backpack.
