So how should we choose and use a hiking backpack? According to experts, backpacks are mainly made of two materials: nylon and CORDURA. The latter is actually a type of synthetic nylon fabric that retains all the advantages of nylon while being more wear-resistant, though slightly heavier. Once you’ve chosen the material, determine the capacity. Generally, hiking backpacks with a capacity of over 50 liters will adopt an “elastic volume” design, meaning the backpack can still be packed tightly after long-term use, making it suitable for various activities. Smaller backpacks under 50 liters don’t require this design.
The most important factor determining the comfort of a backpack is its carrying system. The main function of the carrying system is to distribute the weight reasonably across different parts of the body, avoiding concentration on the shoulders. It also allows for adjustment of the load’s center of gravity to enhance balance and safety during movement. Medium and large backpacks usually feature a frame-based carrying system, which can be either external or internal.
External frame backpacks secure the bag to a rigid frame (aluminum alloy is the most common), equipped with tensioned nylon shoulder straps and hip belts. Their characteristic is a higher center of gravity, around the shoulder or above. This high center of gravity design is suitable for flat terrain but not ideal for situations requiring high balance. The advantage is easy packing and retrieval of items, and the ability to distribute the weight between the shoulders and hips, while providing good ventilation for the back.
Internal frame backpacks have no obvious external frame and often feature detachable or hidden side pockets. They tend to have a slimmer, more upright appearance, hence they’re also called “upright backpacks.” These backpacks contain an internal aluminum frame for structure and include a hip belt to transfer part of the weight to the hips. Their center of gravity is slightly lower and can be adjusted between the shoulders and hips. They are suitable for climbing scenarios where balance is key, preventing the backpack from swaying at shoulder height.
After selecting the right backpack, knowing how to pack it is also an art. Poor packing can affect usability and comfort, or cause the center of gravity to shift and damage the backpack. Therefore, aside from sorting items by purpose, you should also follow these principles when packing:
1. Place heavier items in the middle to upper part and as close to your back as possible. This keeps the center of gravity near your back, avoiding a feeling of being pulled backward. Bulky but light items can go at the bottom, as they won’t affect the center of gravity. Additionally, with heavier items on top, the backpack will become more compact over time.
2. Don’t place hard items against your back, as they can cause discomfort or even injury if you fall. They might also wear through the backpack fabric if they’re only separated by a thin layer.
3. Try to balance the weight on both sides of the backpack to avoid shifting the center of gravity. Items like raincoats, water, and things needed that day should be placed at the top or in easily accessible spots.
4. Use the concept of item categories or pouches. Store similar or frequently used items together in one pouch for easy access—this is especially true for small, loose items.
5. Develop the habit of keeping items in designated spots. This not only speeds up packing but also helps you find what you need even in the dark.
6. Experiment with different packing methods to minimize unnecessary external hanging gear, which can compromise safety and isn’t aesthetically pleasing.
