Are you planning to go on a multi-day trek with a backpack on your back?
In total autonomy, you will need to carry your bivouac tent, sleeping bag, ultralight mattress, water, food, stove, technical merino wool clothing to limit odors, among other small things to prepare, as well as all the essential camping and trekking gear. Therefore, you need a hiking backpack with a "large capacity" starting from 50 L. These large-capacity trekking backpacks are designed to adapt to your body shape and help you carry your hiking gear optimally with suitable and padded straps and belts to improve comfort.
Adult weight (male or female) | Recommended total weight of the backpack | Maximum total weight of the backpack |
50 kg | 7.5 kg | 10 kg |
65 kg | 9.75 kg | 13 kg |
70 kg | 10.5 kg | 14 kg |
90 kg | 13.5 kg | 18 kg |
Choosing the Right Backpack Based on Its Frame
Depending on the brands and models, there are different frames, each with its own advantages and disadvantages. To help you decide in your choice of high-capacity hiking backpack, here are the different types of trekking backpack frames.
Backpacks with tensioned mesh frames
These are the most ventilated backpacks as this tensioned mesh frame allows air to pass between the backpack and the wearer's back. They are ideal backpacks for summer and generally warm countries. Moreover, this frame gives the impression of not having a backpack on your back. However, the space between the mesh and the backpack means that the load is somewhat shifted backward. Therefore, it is advisable to avoid carrying too heavy a load with this type of backpack (maximum 8 kg of load). Also, avoid this frame on steep terrains and for active walking as it is not ergonomic.
Backpacks with padded foam frames
This type of padded foam frame allows for a more ergonomic carry on the wearer's back. This type of backpack is preferred for stability and ergonomics during your treks. Very comfortable, you can carry heavy loads with these backpacks. As for the disadvantages, the fact that they are padded at the back, straps, and belt increases the weight of the empty backpack, but when you plan to carry a heavy load, you are no longer concerned about that, and it is better to have a comfortable, stable, and ergonomic backpack to feel less of the weight. This type of frame is also less breathable.
Backpacks with suspended tensioned mesh
With this type of frame, you have a compromise between the other two. With backpacks with suspended tensioned mesh, you can carry heavy loads while having ergonomics and carrying comfort, avoiding a load shift backward, thanks to the soft 3D suspended tensioned mesh that also allows good ventilation of the back. This frame is notably found in the Osprey backpack range.

Other Important Elements of the Backpack
Straps and hip belt
On this type of large-capacity backpack, the straps and hip belt are generally made from the same materials as the back of the backpack, either foam or mesh. What you must absolutely check if you know you will be carrying a heavy load is that the backpack must have padded straps and belt, as this will directly influence your comfort. Large hiking and trekking backpacks are designed for this and are therefore equipped with dense and comfortable foams throughout the frame of the backpack, perfectly suited for heavy loads. If you plan to carry moisture-exposed gear, invest in waterproof bags for outdoor activities to protect your belongings.
Access, pockets, and accessories
Depending on the models, small accessories can make a difference: included rain cover, trekking pole holder, secret pockets, hydration pack pocket, and hose exit... We tell you more about the essentials to take with you on your treks. The essential accessories for your trail shoes can also enhance your hiking experience.
