The first question that we should ask ourselves when choosing a backpack is what type of activity we are going to do. Backpacks of similar capacity, although designed for a specific activity, are usually versatile, but it is understood that travelling will not be the same on trains and buses through cities, going for a 2-hour run in the mountains, doing an average hiking route or a trek of several days in mid and high-range mountains. From this we can deduce that a backpack "for everything" does not exist.
Beyond the activity to be carried, we can distinguish the following functional characteristics that every backpack should have or be:
- Comfortable to wear and allows us to adjust the weight on our back and not the other way around.
- Easy to pack and access its content.
- Light enough so that the backpack becomes an ally and not an enemy.
- Resistant in terms of fabric and zippers, with reinforcements in the seams of the junction points between fabric and straps.
