Some common mistakes people make when choosing a backpack include choosing a backpack that is too big or too small, not considering the weight of the backpack, and not trying on the backpack before purchasing it. These mistakes can lead to discomfort and inconvenience on your hiking or backpacking trip.

Some additional features to consider when choosing a backpack include hydration bladder compatibility, a rain cover, and a sleeping bag compartment. These features can make your hiking or backpacking trip more comfortable and convenient.

To adjust a backpack to fit your body, you need to adjust the shoulder straps, the hip belt, and the sternum strap. This will help to distribute the weight of the backpack evenly and make it more comfortable to wear.

The best way to break in a new backpack is to wear it around the house, go for a short hike, and pack it with weight and let it sit overnight. This will help to soften the material and make the backpack more comfortable to wear.

It is generally recommended to replace your backpack every three years. However, the frequency with which you need to replace your backpack will depend on how often you use it and how well you care for it.
