Best backpack 50L

There are a great number of 50 liter backpack options, making it a very popular choice for travelling, hiking, and trekking. For air travel in particular, it is important to check the maximum legal carry-on luggage allowed for air travel as most official guidelines do not allow 50 liters as carry-on luggage. The 50L options because of its spaciousness offers you the convenience to pack heavily if you’re visiting a warm climate area. However, you would have to pack lightly and carefully if visiting a cooler climate. Moreover, for hiking, trekking, or backpacking trips of around three days, 50L are rather adequate for clothing, camping gear, and food for the trail.

Factors to consider:

To help you decide the best 50 liter backpack for your specific needs, the following set of factors could be a useful guide:

Frame Type

Backpacks can be classified on the basis of frames as well. Mainly, there are three such types: internal-frame backpacks, external-frame backpacks, and frameless backpacks. Internal-frame packs are body-hugging backpacks designed to keep the structure hidden inside the back panel. As such, the backpack is suitably adjusted to your body such that you remain stable on uneven, off-kilter terrain.

External-frame backpacks on the other hand, have an outside structure that supports the load – for instance, aluminum hardware. An external frame backpack can be helpful if one is carrying irregularly shaped luggage like a tent. These frames also offer great ventilation.

Frameless backpacks are ultralight backpacks for hikers who prefer to hike fast. However, frameless backpacks can be really uncomfortable for heavier luggage.


While internal-frame backpacks are great from the point of view of comfort, mobility, and versatility, they can lead to sweaty backs. Regardless, various such backpacks feature a suspended mesh back panel which provides sufficient ventilation to ward off the sweatiness. This panel is also referred to as a tension-mesh suspension because of its trampoline-like design because some distance is maintained between the person and the backpack, whose back instead rests against the highly ventilated mesh panel. Similarly, other backpacks have ventilation channels to help with this issue.

Backpack Fit

From the point of view of health and safety, this particular feature is perhaps the most important to watch out for. A well-fitted backpack will not place any uneven weight on your body which could be potentially harmful for your back. There are various features that include the right fit but the two most important are torso length and hip circumference. For instance, some backpacks are available in a range of sizes of torso lengths. However, this can largely depend on manufacturer and gender. Most product descriptions include these as essential features or provide an adjustable suspension, such that the backpack can be modified to your torso.

Moreover, waist size can also be a useful factor to consider. More specifically, women-specific and youth-specific designs for backpacks are also available. Similarly, for improved adjustment, sternum and load-lifter straps are sometimes present as additional features to improve your backpack fit.

Keeping these three factors in mind, browse through the following backpack products to decide which one is the best 50L backpack for your next travel plan.

Rain Cover

Most travel backpacks come with a rain cover as hikes and treks can involve unprecedented or precedented rains. Unless one is extremely sure of the climate, it is always better to say prepared with and opt for a travel backpack that comes with a rain cover to protect the material.
